I never heard of anyone here cook one when combined with 3 emitters. I put it in a TR-3T6 a long time ago.. Zero issues with that light. Many have used these before, and I never heard of it failing. Not sure how reliable it is with 4 emitters though. Mode changing is slow and it got some PWM whine.
The one review on KD is not that great though.
HKJ have a review on it too.
It seems so.. 11,75A in this thread.. Sometimes its higher than 7A stock too. I believe Relic38 also resistor modded his for higher output. I don't think 10A is any issue. 12 might be pushing it. Never heard of anyone kill one.
