The yellow StealthLite 2410 LED Flashlight from Pelican has been constructed of durable polycarbonate Lexan EXL resin to make it corrosion proof and resistant to extreme heat and cold temperatures. The lens ring is made of photoluminescent plastic that absorbs light from the LED emitter, the Sun or any other light source. In the dark, the lens ring emits a bright glow, making it easy to find in low light or total darkness. The light is also submersible to 3.3'. Its LED module emits a bright collimated beam that produces 126 Lumen with a distance of 528'. Running on 4 AA Alkaline batteries, it will last for up to 7.5 hours. The convenient thumb switch allows the user to turn it on and off quickly and easily.
