deshunsales at hotmail dot net What I'd like to stress to you is that our main focus is LED replacement bulbs for flashlights. These LED flashlight replacement bulbs are common for flashlights (also 18V tooling flashlights), lanterns or headlamps, such as Miglite and Blackhawk, petzl, Oldham and Decker, Dewalt, Ryobi , Makita and other Flashlights. Flashlight bulbs have many uses, such as general flashlight, emergency lighting of marine products, and tooling flashlight lighting and so on. With service time of 50,000 hours, the LED flashlight bulbs are much brighter and energy-saving than incandescent bulbs. Have I introduced you that our bulbs can work on very very wide-ranging voltages? The voltage options are 1-9V (1-6cells), 2.6-9V, 3.2-9V, 5-30V, which also make the bulbs have broad uses
