Each light fixture is metal with a durable black finish. 2 inches deep by 3.5 inches wide, these fixtures direct light down where you need it, avoiding â€œlight sprawl.â€? Each fixture has a 1 watt, 12 Volt DC LED, which is very bright and provides the same light as a 4 watt standard bulb. The fixture mounts easily to flat surfaces with 2 included screws, and easily attaches to the included low-voltage wiring. The kit is solar powered, and automatically comes on at dusk and turns off at dawn to conserve the battery. The 10 watt solar module can be mounted anywhere with just 2 screws (included). Just make sure to caulk the screws if the module is attached to the roof. Kit includes 2 deck lights, 10 watt solar module, 17 Amphour battery, fused terminal block, small battery box, 50 feet of 16/2 landscape wiring, Night Watchman dusk to dawn switch, 12 amp charge controller, and instructions. Light Color: Cool (5000K) LEDs are rated for 30,000 hours, so less bulb changing! Kit has a 1 year warranty through Solar Conduit. Shipping weight of kit is approximately 25 lbs. Shipping size is approximately 30â€?x12â€?x12â€?. Larger kits with more lights are available via custom order. Contact us with your requirements.
