Luxeon driven w/3 Lithium AA\'s?
Has anyone tried this direct drive? I have been running Luxeons on NiMh 3AA's with excellent light and no heating issues. Alkaline batteries provide a very noticable increase in light output as well as some additional heat (1.35 to 1.55 ah). Obviously there's a point of diminishing return, so can I expect this to live if only used for MOMENTARY use? I've found that 2 AA lithiums are nearly as bright as 3 NiMh AA's.. Maybe I need a four pound block of copper for a heatsink..or maybe for a brain?
