New Model - 16 LED Motion Sensor Solar Light. Dusk to Dawn Security Lighting for Outdoors. Ideal for Walkway, Garden, Yard, Deck, Patio, Fence and Outdoor. External On/off Switch. 16 LED SUPER BRIGHT - The majority of LED wall lights have only 4 LED's providing about 80 Lumen of light. The SolarTronX 16 LED version provides 320 lumen. That's 4 times more light, a huge difference in light output. SCREW IT! or STICK IT! - Super fast installation. Includes 6 pieces of strong 3M double sided tape. Stick it on any flat surface. Also included are 2 screws if you prefer a more permanent fixture. AUTOMATIC BRIGHTNESS - Turns on automatically at dusk and stays in dim mode. When the sensor detects motion, the light will switch to full brightness for approximately 10 seconds. At dawn the light will switch itself off and begin recharging. REPLACEABLE INTERNAL LI-ION BATTERY INCLUDED - UP TO 10 HOURS ILLUMINATION TIME - Many solar lights use a cheaper and inferior Nickel-cadmium (NiCd) battery. NiCd are the lowest quality rechargable battery and will have the shortest lifespan. Lithium-ion are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, no memory effect, and only a slow loss of charge when not in use. Up to 10 hours lighting time when fully charged. NO PIN REQUIRED - External switch to power the unit on and off at any time. The majority of these lights require a pin to be inserted into a hole to turn the unit on and off. Our unit has been redesigned with an external switch.
