I have EDC a CMG Infinity Ultra for several years. I got the military style from CountyComm.com when they still sold them. It has worked great! The single AA lasts for weeks of regular use. It does require cleaning the contacts, once in a while. The Gerber is a China knock-off of the original, but it may still be OK.

Does anyone have experience with the Inova X1? It looks like an interesting light. The package says it is 2 watts.

Thanks!
