I second what everyone else here said.
I bought one of the first CMG Reactors, and it was a puke green color (to quote Craig!) and not really bright.
The mod's from dat2zip, Mr. Bulk and Lambda are great! Really bright, nice color!
The InReTECH 2aa drop in module is a really easy install to an existing mini-mag, and is a nice ballance between brightness and run time.
HOWEVER, for a commercially available product, the CMG reactor is something to be watched. CMG is the first VALUE PRICED Luxeon Star flashlight. CMG is a serious flashlight company, and they did, almost immeditaely, improve their product, and now have a Reactor III. It should be interesting to see how the CPF members rate the Reactor III.
ALSO, it should be noted, that there were SOME CPF members that got really nice reactors, and were very happy with them.
While we might bad mouth the original Reactor (the jury is still out on the reactor III), the Reactor III might be the Luxeon Star flashlight that most consumers will eventually purchase. CMG is an established company with a good market presense.
