The 10 light emitting diodes in this rugged light combine durability with brightness, making this a flashlight worthy of the most demanding handyman or outdoorsman. Because the LEDs are so efficient, this light illuminates for 600 hours on three D batteries traditional flashlights would burn through as many as 500 batteries in that time. And since LEDs are encased in a solid-state resin and do not have fragile filaments, they wont break if dropped or bumped, ensuring the light will be there when you need it. Incredibly bright LED light minimizes reflection and glare without distorting color. Water-resistant and shock-proof ABS polymer with rubber over-molding. 11" L x 2" Diam. (14 oz.)
