     DETAILED DESCRIPTION 
     The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which illustrative embodiments of the invention are shown. Like numbers refer to like elements and different embodiments of like elements can be designated using a different number of superscript indicator apostrophes (e.g.,  10 ,  10 ′,  10 ″,  10 ′″). Abbreviated versions of the word “Figure” such as “FIG.” and “Fig.” are used interchangeably in the application. Broken line boxes in the figures indicate optional features or steps. 
     In the drawings, the relative sizes of regions or features may be exaggerated for clarity. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. 
     It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present invention. 
     Spatially relative terms, such as “beneath”, “below”, “lower”, “above”, “upper” and the like, may be used herein for ease of description to describe one element or feature&#39;s relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90° or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. 
     The term “about” when used with respect to a number refers to numbers in a range of +/−20% of the noted value. 
     As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless expressly stated otherwise. It will be further understood that the terms “includes,” “comprises,” “including” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     Turning now to the figures,  FIG. 1A  illustrates an exemplary electrical device  10 . The device  10  comprises a microcontroller  15 , a light  20  and an onboard secondary power supply or source  25 . The light  20  can provide an externally visible illumination when operative. The light  20  can comprise any suitable light source such as, for example, one or more LED (light emitting diode), a laser, or even a neon lamp, for example. The secondary power source  25  can cooperate with the light  20  to provide low-light illumination for a defined On time of a range of 10-60 minutes or 10-30 minutes, in some embodiments. In some embodiments, the secondary power source  25  can power the light  20  such as an LED light source  25 , providing an LED power draw can be in a range of about 100 μA -1000 μA for a relatively long battery discharge powering time of 30-60 minutes or more. In some embodiments, an LED power draw can be in a range of about 5 mA-10 mA at about 3.3 V for about 30 minutes. For a neon lamp, the voltage to power such a light  20  can be in a range of about 10-60V. 
     The microcontroller  15  can have electrical inputs  15   i  for electrical Vcc and electrical ground inputs of an external or primary power circuit  40  with a hot side branch H and a neutral branch N. Vcc is the voltage provided from the primary power circuit  40  and, in some embodiments, can be in a range of about 1.8V to about 5.5V, which can be rectified and regulated by line-in voltage. The microcontroller  15  can be configured to control/direct when the light  20  is turned On and Off. The microcontroller  15  can have a light control output  15   l  that is connected to the light  20 . As employed herein, the term microcontroller  15  refers to a programmable analog and/or digital device that can store, retrieve, and process data including a digital signal processor (DSP); a programmable logic device (PLD); a combination of a plurality of logic gates; or any suitable processing device or apparatus. 
     The electrical device  10  may also comprise a charge control circuit  30  that is coupled to the secondary power supply  25  and may also optionally be coupled to the microcontroller  15 . Thus, for example, in some embodiments, the microcontroller  15  can also be configured to communicate with the charge control circuit  30  to maintain a charge of the onboard secondary power supply  25 . The microcontroller  15  can communicate with the charge control circuit  30  via a bidirectional connection path  15   c . The charge control circuit  30  is not required to constantly charge the secondary power supply  25 . Rather, the microcontroller  15  can direct the charge control circuit  30  to charge the secondary power supply  25  when the microcontroller  15  detects a drop in a voltage level of the secondary power supply  25  warranting such action. The microcontroller  15  can direct a 120V charge to the secondary power supply  25  when needed. However, the charge control circuit  30  is not required and is not required to communicate with the microcontroller  15  (e.g., no communication or no two-way or bidirectional communication is required). The charge control circuit  30  may be configured to trickle charge the secondary battery or otherwise maintain a charge or provide a supplemental supply of power to the secondary power supply  25  or to the light  20 , when needed. 
     As shown in  FIG. 1A , the charge control circuit  30  can be electrically connected to the secondary power supply  25  via a first connection path  25   c  and to the light  20  via a second connection path  25   i  to provide the power to the light  20  indirectly from the secondary power supply  25 . Alternatively, or additionally, as shown in broken line, the secondary power supply  25  can be directly electrically connected to the light  20  via a third connection path  25   b . The microcontroller  15  can be coupled to a switch  18  in the third connection path  25   b  to control engagement with the light  20 . The switch  18  can be normally open or a normally closed switch. 
     As will be understood by one of skill in the art, switches may be used to connect/disconnect the electrical coupling of one or more of: the microcontroller  15 , the secondary power supply  25 , and/or the light  20 . 
     The external (primary) power circuit  40  can be provided by a line side circuit of a power grid whether private or public. The external power circuit  40  can provide a primary power source to a house, apartment, office building or other interior or exterior space, for example. The primary power circuit  40  can provide the Vcc and ground inputs. The secondary power supply  25  can comprise a battery or capacitor or both. Where a capacitator is used, it can be a super capacitor. Electric double-layer capacitors are known as supercapacitors, electrochemical double layer capacitors (EDLCs) or ultracapacitors and have an unusually high energy density when comparted to conventional capacitors, typically several orders of magnitude greater than a high-capacity electrolytic capacitor. For example, an ultracapacitor from Tecate Group (San Diego, Calif., USA), optionally a PowerBurst® product or a supercapacitor from Cooper Bussmann/Eaton Corporation (Cleveland, Ohio, USA). The super capacitor or ultracapacitor can be configured with a rated voltage of capacitor in a range of about 2.7V-3.3V, and capacitance range from 0.5 to 10 farad or more. Other types of secondary power supplies  25  may be used, such as, for example rechargeable batteries, such as Ni-CD, Lithium-Ion material or non-chargeable batteries, such as Lithium and Zinc/Monovalent silver oxide material. 
     The light  20  can be normally powered by the primary power source  40  and only by the secondary power supply  25  for emergency or back-up powered operation. 
     Referring to  FIG. 1B , no charge control circuit  30  is required and/or the microcontroller  15  is not required to have a direct connection  15   l  to the light  20 . The microcontroller  15  can be coupled via electrical connection path  15   b   2  to a switch  18  in the electrical connection path  25   b  between the secondary power supply  25  and the light  20 . The microcontroller  15  may also or alternatively be connected to the secondary power supply  25  via electrical connection path  15   b   1 . 
       FIG. 1C  illustrates that the electrical device  10 ′ can also include a motion detector/motion detection sensor  35  coupled to the microcontroller  15  via connection  15   m  that can direct the light to illuminate if motion is detected proximate the electrical device  10 ′. The motion detector  35  can comprise, for example, a camera, Hall-effect sensors, optical light emitter and detector pair, infra-red sensors, ultrasonic sensors, gesture sensors or radar wave sensors or combinations of the above or other suitable motion detector configurations 
       FIG. 1C  also illustrates that the electrical device  10 ′ can have a user input  45  that allows a user to turn the light  20  either On or Off. As will be discussed further below, the user input  45  can be provided as a manual input and/or via an electronic input that may be accessible by an APP  145  ( FIG. 6 ). A timer  15   t , which may be provided by the microcontroller  15 , may be used to have the light  20  return to the Off state if a user does not turn the light Off when in a defined time. The On time may be adjustable and set by a user and may have a default setting of suitable time frame, such as, 5-10 minutes, for example. 
     The electrical device  10 ,  10 ′ can also be configured to only direct the light  20  to illuminate if a proximity space is dark or has reduced lighting relative to a defined light threshold. Thus, the electrical device  10 ,  10 ′ may also include a light sensor  55  as shown in  FIG. 1C . The light sensor  55  can be connected to the microcontroller  15  via connection path  15   s . The light sensor  55  can be provided as one or more types of light sensors including, for example, a CDS photocell (also known as a light dependent resistor where resistance changes based on the amount of light), an ambient light sensor (ALS) and/or a digital light sensor. 
     The electrical device  10 ,  10 ′,  10 ″( FIG. 6 ),  10 ′ ( FIG. 10A-10C ) can be configured, for example, as a switch, GFCI, AFCI, USB product, smart dimmer product or night light device and the like and any combinations of these example devices. 
     Referring to  FIGS. 2A and 2B , in some embodiments, the electrical device  10 ,  10 ′ can be configured so that when the line load is active, e.g., the primary power circuit  40  is active/powered and powering the electrical device  10 ,  10 ′, the light  20  is powered by the primary power circuit  40  and the secondary power supply  25  is inactive, disconnected from the light  20 . The electrical device  10 ,  10 ′ is configured to detect when load to the device  10 ,  10 ′ is disrupted and then provides power to the light  20  from the secondary power supply  25 . 
     As shown in  FIG. 3 , the electrical device  10 ,  10 ′ can be a power receptacle  10   p . The term power receptacle  10   p , can also be interchangeably referred to as a “receptacle” or “outlet”. As is well known, a power receptacle is a point of connection between electrically powered devices, such as computers, and a power distribution system, such as a power distribution circuit  40  of a structure such as a building. The power receptacle  10   p  can have a housing  10   h  and can be configured, for example, as an in-floor, in-wall device, surface-mount device, or a device integrated into another device or even as an appliance. 
     The power receptacle  10   p  can be configured as a single plug-in receptacle  60 . In some embodiments, the receptacle  10   p  can be configured as a single gang, dual gang or duplex receptacle, or other multiple gang receptacle.  FIG. 3  illustrates that the power receptacle  10   p  can comprise two plug-in receptacles  60   1 ,  60   2  providing a duplex receptacle configuration. The light  20  can be configured to illuminate via a translucent window  20   w  between the two receptacles  60   1 ,  60   2 . However, the light  20  can be configured to illuminate via other windows included about the perimeter of the device, for example. The receptacle  10   p  can be a three-phase receptacle of suitable amperage and voltage rating for residential or commercial use. In some particular embodiments, the receptacle  10   p  can be a 15A or 20A rated device. 
     The light  20  can be configured to emit with a first color when powered by the primary power circuit  40  and a second different color when powered by the secondary power supply  25 . 
     The electrical device  10 ,  10 ′,  10 ″,  10 ′ can be a plug-in device that can have external terminals that plug into an electrical power receptacle. 
     Referring to  FIG. 4 , the electrical devices  10 ,  10 ′ can be provided as a system of electrical devices  100  configured for wireless network communication with a plurality of electrical devices related by a defined zone  100   z , shown as three defined zones,  101 ,  102 ,  103 . Each defined zone  100   z  can have one or more electrical devices  10 ,  10 ′. Different numbers of electrical devices  10 ,  10 ′ with respective onboard lights  20  can be used in different zones  100   z . The electrical devices  10 ,  10 ′ can be configured to allow multiple such devices  10 ,  10 ′, which may be described as nightlight products, to connect to each other within a defined zone  100   z . A motion detector  35  ( FIG. 1C ) in a first electrical device  10 ,  10 ′ in one zone  100   z  can direct a corresponding light  20  to turn On when it senses motion, such as a person walking by. The electrical devices  10 ,  10 ′ can be configured to communicate via a wireless network. The first electrical device  10 ,  10 ′ in the one zone  100   z  can be configured to signal to the other devices  10 ,  10 ′ in the same zone  100   z  (e.g., same range/room) that they should all turn their respective lights  20  On. The first electrical device  10 ,  10 ′ can be configured to send a signal to all other electrical devices  10 ,  10 ′ in the same zone  100   z  to turn their respective lights On, using a low power (or ultra-low power) RF signal of 5 mW or less, for example. The communication network and/or protocol providing the RF signal can be off the shelf or custom RF or Bluetooth or other low energy RF network/protocol such as, Z-Wave, ZigBee or any similar network or protocol. These communication/control protocols have very low current draw (e.g., a few milli-amperes) during steady state, RX/TX modes. The term “low energy” when referring to RF networks and protocols refers to those RF/communication/control networks and protocols that operate with about 5 mW or less during the TX and RX operations. 
     The lights  20  of the electrical devices  10 ,  10 ′ in in all other zones  100   z  can remain Off until a motion is detected by one of the electrical devices  10 ,  10 ′ in that zone  100   z . Upon activation of a respective light  20 , the electrical devices  10 ,  10 ′ can all operate on a timer  15   t  ( FIG. 1C ) after they turn On. This timer  15   t  can be synchronized so that each time motion is detected by a motion detector  35  in a respective zone  100   z , a reset (light) On time signal can be sent to all other electrical devices  10 ,  10 ′ in that zone  100   z  to operate on a common light duration On time and this time can be reset within a respective zone  100   z  every time motion is detected by a motion detector  35  of an electrical device  10 ,  10 ′ in a respective zone  100   z . When the set time of the timer  15   t  runs out or expires, a respective electrical device  10 ,  10 ′ can turn its corresponding light  20  Off. 
     A user, such as a home-owner or resident, can electronically direct (e.g., over a wireless network) or manually (e.g., using an external input member  45   m  ( FIG. 8 ) such as a touch screen lens, push button or external paddle switch) any individual or zone of electrical devices  10 ,  10 ′,  10 ″,  10 ′″ to remain with a respective light  20  On for an extended period and thereby by-pass or disengage the timer  15   t.    
       FIG. 5  illustrates that the system  100  can be provided as a kit  100   k  with a plurality of electrical devices  10 ,  10 ′ and a sync module  110  which can be used to define the zone relationship by correlating a physical location and electronic address for each device  10 ,  10 ′ at set-up. The sync module  110  can communicate with each device  10 ,  10 ′ and a wireless network  125   w  ( FIG. 4 ) in a building. 
       FIG. 6  illustrates that the electrical device  10 ″ can include a (radio) transceiver  50  and a sync module interface  55 , both or either one of which may be provided by the microcontroller  15  or directly or indirectly coupled to the microcontroller  15 . For example, the microcontroller  15  can be configured as or be coupled to a wireless microchip module with general purpose input output (GIPO) connections, a receiver and a transmitter and various sensor, antenna and power inputs/outputs as is well known to those of skill the art. For example, a separate sync module  55  can be provided and connect to the local wireless communication system and to the electrical devices  10 ,  10 ′,  10 ″,  10 ″′. For example, the sync module  55  can be provided as part of a smart home control system. By way of example only, an RN171 microchip from Microchip Technology, or any suitable wireless module microchips may be used for the microcontroller  15  and/or the sync module  55 , for some embodiments. 
     Still referring to  FIG. 6 , the electrical device  10 ″ can be configured to wirelessly (and remotely and/or locally) communicate with a user via a light control APP  145  providing a user input  45 . The light control APP  145  can be accessible via an icon on a mobile device  200  of a user. The term “APP” refers to a computer program configured to provide defined functionality on a computer including pervasive computing devices and/or mobile devices such as an electronic notebook or notepad, smart phone, laptop, and the like. In some embodiments, the functionality of the APP may be accessible via an icon  145   i  on a display of the computer and/or may be accessed by other user input, such as input provided by a typed or spoken user interface of the computer. The computer program may comprise computer program code configured to reside in a memory of the computer to be accessed and executed by a processor or other computing circuit of the computer, but the embodiments of the invention are not limited thereto. In some embodiments, the computer program code, processor, and/or memory may be located remotely from the computer providing the functionality, such as in a networked environment, or “cloud.” 
     The light control APP  145  can be configured to have suitable network security for access by any user. The access may be controlled using an “electronic key” or “digital key” such as a defined electronic alphanumeric code that is associated with a respective user. The digital key can be provided to a mobile device  200  having a unique identity code associated with a mobile device of a respective user, such as, for example, an International Mobile Equipment Identity (IMEI) and/or an IP address. The digital key can be provided by an APP  145  or other electronic key generation and/or identity verification system. The digital key can be provided by an authorized user database and/or user access system in communication with an authorized user database. The digital key can be provided via a communications interface including, for example, a Bluetooth communication connection with a respective mobile device. The digital key can be entered via a Human Machine Interface (HMI) such as via a display user interface or a keypad or reader input and may use a two-step verification protocol by sending real time alphanumeric digital keys to a user to allow a secure light On and/or light Off command be wirelessly sent to various electrical devices providing a light or lights  20  in one or more zones  100   z.    
       FIG. 7  illustrates example control/input pages  245   1 ,  245   2 ,  245   3  that can be accessed via the icon  145   i  of the light control APP  145 . As shown, one page  245   1  can identify the devices  10 ,  10 ′,  10 ″ by zone location  100   z  (zone  1 , zone  2 , zone  3 , for example). Each device  10 ,  10 ′,  10 ″ can identify its status as primary power active (On) or disrupted (Off) and current light status as On or Off. Each may have a graphic symbol for On and Off (light bulb illuminating or off or marked with X). For primary power, a lightning bolt graphic can be used when active and an X through the lightning bolt graphic when the primary power is off. However, other status indicators may be used. 
     Each electrical device  10 ,  10 ′,  10 ″,  10 ′″ can be controlled via the light control APP  145  to have an On or Off state by the electronic input  246  on the page  245   1 . A user can customize the name of a particular zone  100   z  using the APP  145  according to their use, e.g., kitchen, bedroom  1 , family room, for example. 
     A second page  245   2  can be used to provide an alert to a user when primary power is Off and/or when a light is On, for example. This may help a user know when a fuse is blown or when power to the entire house is disrupted and the alert can be sent remotely to one or more mobile devices  200  connected to the lighting system  100 . The alert can include an audible alert, that can have a sound and decibel level that can be set by a user. 
     A third page  245   3  can provide a status that indicates whether any secondary power supply  25  is activated on any device  10 ,  10 ′,  10 ″ and/or if primary power  40  is disrupted to any device  10 ,  10 ′,  10 ″ and/or zone  100   z.    
       FIG. 8  illustrates another example of a power receptacle  10   p  providing the electrical device  10 ,  10 ′,  10 ″, As shown, the power receptacle  10   p  includes a test and reset input members  120 ,  121 , respectively. The input members  120 ,  121  can reside adjacent the light output window  20   w , The power receptacle  10   p  can include the manual input  45   m  for the user input  45  that can allow a user for turning the light  20  On and Off. 
     As shown, the plug-in receptacle  60  can be configured as a 3-prong socket but a two-prong socket may also be provided. 
     As shown in  FIG. 8 , the receptacle  10   p  can include outer bracket ears  124  that can include mounting (typically threaded) members  125  that can be used to attach to a desired structure for mounting the power receptacle  10   p.    
     The receptacle  10   p  can be configured as an Arc Fault Circuit Interrupter (AFCI) and/or Ground Fault Circuit Interrupter (GFCI) receptacle. As is well known, AFCI and GFCI receptacles are among a variety of overcurrent protection devices used for circuit protection and isolation. A GFCI is a device that shuts off an electric circuit when it detects that current is flowing along an unintended path to reduce the risk of electric shock. The GFCI can be manually reset by pushing the reset button. An AFCI can be designed to help prevent fires by detecting an unintended electrical arc and disconnecting the power before the arc starts a fire. 
     Thus, the power receptacle  10   p  may be configured for other AFCI and/or GFCI applications. For example, as shown in  FIG. 8 , the receptacle  10   p  can be a GFCI and/or AFCI receptacle unit with an external user-actuatable button or member on the face of this power receptacle unit  10   p . There power receptacle  10   p  can include a manual input  45   m  that can be manually used to illuminate the light  20  whether by the primary power circuit  40  of the secondary power supply  25 . The manual input  45   m  can be used as a simple switch or it can be wired for GFCI (or AFCI) protection. The power receptacle  10   p  can have a test/reset input(s)  122  also on the face of the unit. 
     The electrical device  10 ,  10 ′,  10 ″,  10 ′″ may be configured to operate the light  20  without the primary power circuit  40  due to several conditions. For example, a AFCI or GFCI device can itself terminate power connection to the primary power circuit  40  when a fault condition (current in an unintended path or an unintended electrical arc) is detected. 
     Power from the power circuit  40  may also be disrupted at a fuse box or outside and upstream of a respective building in the power grid. 
     The electrical device  10 ,  10 ′,  10 ″,  10 ′″ can be configured to direct a light output from a light  20  to be in different colors or tones of color based on different defined conditions and/or parameters. The colors may be based on what type of power outage occurs at a particular device  10 ,  10 ′,  10 ″. For example, a first color when the electrical device  10 ,  10 ′,  10 ″ is no longer connected to the power circuit  40 , a second color when power from the power circuit  40  is lost, and a third color when more than one device is no longer powered by the power circuit  40  indicating a grid power disruption. These different actions can provide different colors that reflect, for example, whether power issue is due to a power outage of the power grid, a fuse in a branch circuit or onboard an AFCI/GFCI disconnection. The light may be configured to have a pulsed output when time from powering the light  20  is beyond a defined time threshold of 30 minutes, for example, and the frequency can increase or decrease as the time from start of secondary power powering increases. Thus, the actions can output a light color and/or a visual output presentation that changes based on a cumulative time from a disruption of a powered state by the primary power circuit  40  of the electrical device  10 ,  10 ′,  10 ″. 
       FIG. 9  illustrates exemplary actions for lighting systems with synchronized lighting of zones in spaces of a building, such as an apartment, residence or office or even airport terminals. The actions may include providing a plurality of electrical devices with onboard lights and onboard secondary power supplies (block  500 ); defining a zone relationship of different devices in different defined zones (block  510 ); powering the electrical devices with an external power circuit during normal operation (block  520 ); detecting a termination of a powered state from or between the primary power circuit (block  530 ); and automatically powering the light using the secondary power supply (block  540 ). Each of the devices may include a motion detector and upon detecting motion by one of the electrical devices in a first zone of the defined zones, directing other electrical devices only in that same zone to illuminate their lights (block  550 ). The actions can include automatically turning all lights off in the defined zone a defined time from when motion is last detected from a last to detect of the motion detectors in that defined zone (block  560 ). 
     The system can be configured to allow a user to turn one or more of the lights On or Off (block  502 ). 
     The system can be configured to operate with a light control APP that wirelessly communicates with the electrical devices using a wireless computer network (block  512 ). 
     A power outage alert can be sent to a user associated with the devices that defines a type of outage that occurs for a zone and/or electrical device within each zone (block  515 ). 
     Turning now to  FIGS. 10A-10C , the electrical device  10 ′″, shown as a power receptacle  10   p , can be configured to illuminate with one of a plurality of different, user-selectable, colors. 
     In some embodiments the selectable colors are selectable color temperatures of a respective color, shown as cool white, warm white, and neutral white, by way of example. To be clear, “white” is included in the term “color” although it may be considered a “shade” rather than a true color by some. The term “color temperature” is used broadly to refer to a visual change in appearance of a color from a first tone or hue to a second tone or hue. 
     The electrical device  10 ′″ can be configured to output a plurality of predefined colors and/or color temperatures at the light output window  20   w  overlying the light source  20 , whereby a user can toggle through the plurality to select one for current visual output. 
     The plurality of predefined colors and/or temperatures can be selected via a user touch input  45   t  via the light window (lens)  20   w  so that the electrical device  10 ′″ provides a desired color (temperature) output. 
     The color output  220  can be provided so that one color temperature presents with a warmer (white) temperature  2202 , one temperature presents with a cooler (white) temperature  220   1  relative to a neutral (white) temperature  220   3 . The cool temperature light output  220   1  may present a light output with increased luminosity relative the warm temperature output  2202  and/or the neutral temperature output  220   3 . 
       FIGS. 10A-10C  also illustrate that the light output window  20   w  can be provided as a rectangle between plug-in electrical sockets  60   1 ,  60   2 , according to some embodiments of the present invention. 
       FIG. 11  illustrates a block diagram of an example electrical device  10 ′ providing a color (temperature) circuit  1200   c  configured to provide the multiple color temperatures  220  shown in  FIGS. 10A-10C . The electrical device  10 ′ can optionally be provided as a plug-in electrical power receptacle  10   p . The color (temperature) circuit  1200   c  can include an AC to DC power supply  40  coupled to a light source module  1200   m  comprising at least one LED  20 L as the light source  20 , an LED driver  1200  and a color (temperature) select circuit  1205 . The light source module  1200   m  can be coupled to a microcontroller  15  (which can also be coupled to the secondary power supply  25  (e.g., battery/or super capacitor). The power supply  40  can be coupled to the microcontroller  15  as well as the color temperature circuit  1200   c . A user can change the color and/or color temperature by pressing the user input  45   t , which can be configured as a push button interface, on an outer surface of the electrical device  10 ′″ and/or provided as a remote software interface, such as via an APP  145 , as discussed above with respect to  FIG. 6 . 
       FIG. 12A  illustrates a circuit diagram of an electrical device  10 ′″ providing the color (temperature) circuit  1200   c  with the color temperature module  1200   m  according to some embodiments. The color (temperature) circuit  1200   c , similar to that discussed above with respect to  FIG. 11 , includes a power supply  40 , the light source module  1200   m  with the at least one LED  20 L, the LED driver  1200  and the color temperature select circuit  1205 . The light source module  1200   m  is coupled to the microcontroller  15 . The microcontroller can be coupled to a light sensor  55  and the user input  45  or multiple different user inputs such as other light control outputs  15   l , APP interface  145   i , and touch input  45   t.    
       FIG. 12B  illustrates an example of a portion of the color temperature circuit  1200   c  shown in  FIG. 12A  with the color temperature module  1200   m  comprising one or more LED  20 L, e.g., comprising a plurality of LED die or a plurality of LEDs  20 L. As shown, the color temperature circuit  1200   c  can comprise first and second sets  20   p  of LEDs  20 L, with each set (optionally a pair)  20   p  of LEDs  20 L coupled to a driver  1205   1 ,  1205   2 . One set  20   p  of LEDs  20 L is active when a first color temperature is selected and the other set  20   p  is active when a second color temperature is selected. All sets can be concurrently active to provide yet another color temperature(s). 
       FIG. 13  is an example flow chart of actions that can be used for color (temperature) selection according to some particular embodiments of the present invention. To enter the light selection mode, when the light is off, a user can press and hold the user input button (which can optionally be the light lens touch button) for a defined time, such as 5-15 seconds to initiate the process (block  600 ). A user can apply a first user input to activate a color selection mode which turns off any of the at least one LED which is in a powered on/illuminating state prior to allowing the device to enter the color selection mode. As an indicator that the light color selection mode is active, the LED can blink ( 602 ). If the user input is released before the defined time of block  600 , such as within 2-10 seconds, such as about 3 seconds, about 4 seconds or about 5 seconds, the light is turned off and the light selection mode ends (block  610 ). If the light selection mode is activated, the light can be changed by cycling/toggling through predefined light output settings (block  620 ). The click toggle button can change the setting and make a cycling change with several clicking actions to/of the button. The predefined settings can be color temperatures of cool, neutral, warm. Once the light selection mode is activated, the light can be turned on with a current or default light setting/brightness level (block  622 ). A user can press the user input button during the light selection cycle within a defined time, such as about 10 seconds (block  630 ). If the user input button is pressed during the light selection cycle within the defined time, a user can then press and hold for another defined, shorter time, such as 1 second, and then release when the LED blinks to save and exit the light selection mode (block  640 ) and the mode is exited and the light turned off (block  642 ). If the user input button is not pressed within the defined time of block  630 , the mode is exited without saving any light change selection (block  635 ). The light selection mode can end (block  650 ). 
     The light selection/change mode (e.g., LED color change mode) can be active both in a continue and step mode.
