     TECHNICAL FIELD OF THE INVENTION 
     The present invention relates in general to light fixtures and more specifically to light fixtures that are configured to output luminosity and/or light color-temperature from within predetermined ranges of luminosity and/or light color-temperature. 
     COPYRIGHT AND TRADEMARK NOTICE

The owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyrights whatsoever.

     BACKGROUND OF THE INVENTION 
     It is often desirable for different rooms or even different regions of a same room to have ceiling (or wall) mounted light fixtures that output light at a given luminosity and/or that output light at a given light color-temperature. For example, it may be desirable to output light differently in a kitchen, pantry, living room, dining room, lounge, entertainment room, media room, great room, hallway, flex room, gym, studio, bathroom, bedroom, study, foyer, office, lab, work area, waiting room, mud room, garage, shop, deck, porch, patio, portions thereof, combinations thereof, and/or the like. It would be desirable if a single type of light fixture was capable of outputting light at different lumens and/or was capable of outputting light at different light color-temperatures. It would be further desirable if the different outputs of lumens and/or the different outputs of light color-temperature were selectable via one or more switches of that single type of light fixture. Thus, such a single type of light fixture could be used in multiple locations in different rooms and/or within the same room to achieve different lighting effects. Having such a single type of light fixture could avoid needing to use a variety of different types of light fixtures, wherein each different type of light fixture only has a light output of a single specific luminosity and/or that has a light output of a single specific light color-temperature. 
     It is to these ends that the present invention has been developed. 
     BRIEF SUMMARY OF THE INVENTION 
     To minimize the limitations in the prior art, and to minimize other limitations that will be apparent upon reading and understanding the present specification, the present invention may describe various light fixtures. In some embodiments, a given light fixture may be configured for (removably) mounting within a given housing-can. In some embodiments, the light fixture may comprise a driver assembly, a heat-sink and a trim-casing assembly. In some embodiments, the driver assembly may comprise a driver-printed-circuit-board, a lumen-switch, a color-temperature-switch, and a driver-box. In some embodiments, the driver-printed-circuit-board, the lumen-switch, and the color-temperature-switch may be at least partially housed within the driver-box. In some embodiments, with the lumen-switch, a lumen output of the light fixture may be selected. In some embodiments, with the color-temperature-switch, a light color-temperature output of the light fixture may be selected. In some embodiments, the trim-casing assembly may comprise a light-emitting-diode-circuit, a reflector, a lens, a can-attachment-means, and a trim-casing-member. In some embodiments, the light-emitting-diode-circuit, the reflector, and the lens may be housed within the trim-casing-member. In some embodiments, the can-attachment-means may be attached to an exterior of the trim-casing-member and may be configured for attaching the light fixture to the housing-can. In some embodiments, the heat-sink may be disposed entirely below the driver assembly and entirely or at least partially above the trim-casing-assembly. 
     It is an objective of the present invention to provide a light fixture for (removable) mounting within a housing-can. 
     It is another objective of the present invention to provide a light fixture with a lumen output selection switch. 
     It is another objective of the present invention to provide a light fixture that is configured to output light at different lumens from a range of predetermined lumens. 
     It is another objective of the present invention to provide a light fixture with a light color-temperature output selection switch. 
     It is another objective of the present invention to provide a light fixture that is configured to output light at different light color-temperatures from a range of predetermined light color-temperatures. 
     It is another objective of the present invention to provide a light fixture that is configured to receive and operate at a predetermined voltage. 
     It is another objective of the present invention to provide a light fixture that is configured to receive and operate at a predetermined wattage. 
     It is another objective of the present invention to provide a light fixture where a LED-chip/board, a reflector, and a lens are all entirely housed within a trim/casing member of the light fixture. 
     It is another objective of the present invention to provide a light fixture where a heat-sink is located entirely below a driver assembly and entirely above a trim-casing assembly. 
     It is yet another objective of the present invention to provide a light fixture where a heat-sink is located entirely below a driver assembly and partially above a trim-casing assembly (with the an upper-portion of the trim-casing assembly extending into a bottom inside of the heat-sink). 
     These and other advantages and features of the present invention are described herein with specificity so as to make the present invention understandable to one of ordinary skill in the art, both with respect to how to practice the present invention and how to make the present invention.
