I recently bought a 55mW flashlight- its really bright but, the beam diameter/divergence is that of.... a flashlight.... Is there any mirror set I can rig up, or do anything to at least get a focused point on it at some distance? I don't mean giving it a beam, just a reversed divergence (invergence?) so that somewhere, a point of concentrated light would exist (that would hopefully burn something. )

is it just me, am i confused. Because the title says 55mW flashlight. 55 mW as in milliwatt. For a flashlight thats tiny! Isnt the torch like 100 Watts as in 100,000mW? Or have i got the wrong end of the stick? I cant wait for the torch reviews, i check every day as soon as the start to confirm that they are that powerfull im having one Back to this thread, I guess we are trying to merge the gap between lasers and flashlights. Like mega powerfull torches with 1/2 a foot beam diameter. As vic said it wont be collimated. But there will be ways of making it a burning tool. There always is _________________ Thanks, Phil WATCH MY YOUTUBE CHALLENGE ENTRY HERE READ MY CROSSFIRE 300mW REVIEW HERE

A camera lens could focus the beam well enough. Lookout for such at flea markets and practically junked cams
