Designed for the firefighter, the Big Ed is the choice of flashlight for the turnout gear. The unbreakable ABS body resists chemicals, water, and corrosion. Rubber side grips prevent slipping and the push button switch on the side is easy to operate, even with thick gloves. For hands-free use, a heavy duty stainless steel clip is built in. The 3700 uses a hi-intensity Xenon lamp that produces a beam strong enough to cut through thick smoke and dust. A back-up emergency lamp is housed behind the reflector. Battery replacement is easy with its quick change battery ejection system. The Big Ed is powered by 4 C alkaline cells.
