There are plenty of really good reviews of the K1 with the W1 or W2 LEDs, but I can’t seem to find any reviews with the 90.2. Can anyone point me in the direction of a good review? I’m really interested in seeing what kind of current it pulls, and what its thermal performance and runtime curves are. It seems to do really well with the smaller LEDs, but the 90.2 is a such a beast that the numbers would be pretty different.
I assume it will pull a high current (10A + at least)
