Maybe it isn’t, just bad measuring, or a typo. tatasal may notice it if the tint is badly purple on highest mode? (slightly purple compared to lower modes I found is pretty normal at 5-ish amps).
Edit: wait, scratch that, you do realise that this is the 2 mm2 die area White Flat that can handle more current?
Hmm… I dedomed warm xp-g3 recently and when I’ve ran it @5A it got purplish too. So you think it’s the same reason? Overdriven? Or the result of dedoming warm (7A I guess) led?
Ugh, I just bought this one in 21700. I've got to stop this madness. I've bought the BLM FW21, he Convoy M21 SST40 5000k and now this. This is because I lost my 900lm feix 35.
