buy these a while back and get the two-pack for about 8 buck . I have both a DeWalt 18v and a Ryobi 18v flashlight . both take the same bulb , and these DeWalt xenon bulb be bright and hold up pretty well to shock and vibration -lrb- I have drop both light more than once and the bulb -- as well as both of the flashlight -- can take a reasonably good beating -rrb- . but recently I have find the same bulb -lrb- look like same manufacturer , too -rrb- brand under the Craftsman name at both Sears and OSH -lrb- for those of you in California -rrb- sell for $ 1.49 each . lot easier to find one there when you need it in a hurry .
