CatEye Econom Bicycle Headlight HL-EL340
Ecology meets Economy in the CatEye Econom head light. ROL™ (Reverse Offset Lens) technology  produces a whopping 1,000 candlepower in this powerful package.  Featuring three distinct lighting options, the included 2 AA batteries will power the Econom for  up to 100hrs in the flashing mode and a recharging port allows you to upgrade to rechargeable  batteries in the future. The high and low constant modes have a 7hr and 20hr runtime, respectively.  A low battery indicator keeps you from getting caught in the dark.
