The DropLED Pro, from Lumen LED, delivers 1,100 lumens at a safe 145 degrees F, so it won't burn the user, ignite fuel or cause an explosion. Virtually indestructible, the DropLED Pro has been tested after 300 hits to cement and crushing under a forklift, still performing at the same brightness and functionality. This light comes with a full five-year warranty. At 12W, the energy savings can pay off the purchase of the tool in two years, although the savings in bulbs and lost shop time turn it around in a month. The DropLED Pro is UL-listed, Mercury-free and operates at a color temperature of 4000K, for perfect detail and accurate color.
