The popular 2600 has been outfitted with the Recoil LED module. What you get is a hands-free light that's extremely powerful, durable, and efficient. The 2680 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, submersible, and virtually indestructible. It is powered by 4 AA alkaline cells (included) and comes with a rubber strap for hard hat use and an adjustable cloth strap for bare heads.
