I don't see any difference in output using aw imr vs normal aw 16340 rcr's with the mini-x. Even my camera cant pick up any difference on stopped down photos. I guess all the components inside the driver might have some resistance, and might act like some kind of bottleneck. (It's not thick wires going criss cross inside that tiny driver, so i think the extra current from the imr has a hard time pushing trough that driver).
I just added artic silver and taped one of the temprature sensors from my pc on to the mini-x so I could monitor the heat build up. It was tailstanding on top of my pc ( It's a fan on the top of it, so it was a good place to tailsatnd it, kind of safely) There was no big temprature difference after a 2 min run between normal aw and aw imr.
Too keep it short: The normal aw rcr messured 40.7 celsius after 2 min, imr 40.5 celsius @ 2min :huh:. A 4sevens cr123 showed 32,6 celsius @ 2 min and 40.7 after 5 min 30 sek. The temprature at the led itself is unknown, temprature on every startup was 23.5 C.
The light is hotter than the sensor claimes because it's thin as a hair, and only 2 layers of tape was insulating the thin sensor from the "cooling enviorment". A laser might give accurate readings, but i just wantet to see if I could messure any difference between imr and a normal 16340
