I bought a Nite-Iize LED conversion for my mini-mag and liked it so much that I bought a second one for my other mini. I notice though that one of the LED conversions is more of a greenish color and the other one is more blue. I've read on this forum that LEDs often turn green before going out completely, but is that necessarily true? Could it be that it's just a "greenish" LED array that they put in there and not a "bad" one?
