Adjust the pattern of these lights quickly by switching from steady on to twinkling mode with the press of a button. LED LIGHTS - LED bulbs are the newest trend in lighting and can outlast the life of a compact fluorescent bulb by up to 10 times (even longer for incandescent). Traditional incandescent and CFL bulbs produce heat build-up that tends to overheat the area where they operate. LEDs prevent this excess heat output resulting in a cooler more efficient lighting system. SOLAR POWERED - These stake lights utilize the natural power of the sun to operate. An amorphous solar panel absorbs light during the day and recharges the 900mAh battery for use in the dark. This eliminates your need to swap out batteries or install a costly outdoor power system. INSTALLATION & USE - Have you ever begun to install something just to realize that you need to go buy additional parts? Reusable Revolution has solved that problem by including plastic stakes and Ni-MH batteries for each stake light. No tools or external wiring is required resulting in a quick & simple installation process. Once installed just switch the unit on and youll never have to worry again thanks to an automated feature that turns these lights on or off based on the surrounding light. DIMENSIONS - Measures 55 feet long
