A triple XHP50 will generate too much heat for this light, it can sustain output for a few seconds.
For a triple XHP50 you need a decent host with good thermal mass and heatsinking.
Exactly Yokiamy. why waste good leds in such a way. People seem to want gadgets that can peform for seconds. Like a party trick or top trumphs. To each their own ofcoarse but function for me is way more important.
As much as I like lots of lumens, 3x XHP50.2 in a single 18650/21700 EDC light just makes no sense. That's way over 100W it will throttle in what .. <5 seconds?
For what it’s worth, I’ve continued working on the thermal regulation. It has a tighter window now, a smaller range of temperatures it’ll accept… so it stays closer to the configured temperature. I also got it to adjust faster while still not overshooting or bouncing.
The runtime graph isn’t completely flat any more, but that’s probably a good thing. On a linear driver like this, it gets more efficient as the battery gets low, so it makes less heat, and then it naturally increases the brightness to maintain a steady temperature. This effect is fairly small though, and happens very slowly, so it’s not visible by eye.
It is not necessary to use the flashlight only in turbo modes. In weaker modes, the XHP50 will be more efficient and less hot than small XPL/SST… .
I hope Hank pay attention to the emitters XHP
As always, we offer various different CCTs if we decide to offer one type of LEDs, 2000, 3500K, 4500K, 5000K will be offered when they are available.
But there is no ETA yet since the Japan Nichia factory is locked down.
