Same as the Little Ed 3600 but outfitted with our Recoil LED Technology. The Little Ed 3610 Recoil LED Zone 0 uses a 1-Watt LED that's aimed backwards into the reflector. 100% of the light is captured and aimed forward as a tight collimated beam that's as bright as an incandescent. The body is made of tough ABS resin that's corrosion proof and resistant to extreme temperatures. It is powered by 4 AA alkaline cells (included). Certified to ATEX Zone 0 (Category 1).
