After applying quite some force without any other success than adding some small scratches to the bezel, I peeled out the o-ring with some very fine tweezers and heated the head with a lighter, the glue softened and with little force the bezel came off.
I added an 8th AMC7135 and reprogrammed the driver with my custom firmware. I’m just too pampered by my firmwares to go with a normal one
After 10 min on high, tailstanding in 25°C ambient temperature, the case temp was 68°C (bad for the batteries!) and the LED temp was 117°C (according to an IR camera).
I used it at work today…Over all I’m still impressed… It may replace my Quark…
Longest duration I used it was on medium for 10 min and it does get warm. Its what I expect for the size… On high you can feel its warmth at the head after 5 seconds. I noticed it often today……my Xeno warms up similarly.
I would not use this as a bike light, but for my specific day to day work use it was really nice. I honestly enjoyed it and experienced a bit of that ‘wow’ factor.
It fits. 20mm TIR lens that is with room to spare. I don't have anything to measure right now but I'd say its the same size as the stock reflector. The inside lip of the bezel helps center the TIR lens with the stock glass lens removed.
Memory on these drivers should settle about 2 sec after you chose the desired mode. No memory.. yeah, if you build it yourself (empty host from CNQG, any emitter and a KD V2 driver).
I just switched the driver to a KD v2, 3.05A driver. Low - Med - High with memory. I'm using the 2.5A driver that came with it to power another light. It was very easy and quick 10min job. I'm not sure if my eyes are playing tricks on me but it looks considerably brighter. Might be that it was dark outside...
