Cool, what colour trits are available and for how much?
Interesting, why not Cyan body with Cyan trit?
I didn’t really have a list of colors in front of me…
Yet another pm
Hank, is there a version with 3x xhp50.2 coming 
+1
Why would you want that much heat?
Because of lumens. Only question is who will the first one to make an EDC triple xhp50.2
Lumintop’s upcoming FW21 PRO perhaps?
+1 or 3x xhp70.2 
I’d rather get a single emitter + reflector version of the D4 or KR4 before any completely impractical versions.
Something like the D18 with a few XHP50s or 70s could be interesting though… Same with the K1 for a much higher quality competitor to the FT03 w/XHP50.2
I heard that a KR1 may be coming in several months.
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.
Please don’t tease me like that.
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?
I’d be massively down for a KR1. I haven’t ended up getting a FW1A, so this’d make a great replacement and keep things a bit diverse.
I’m so temped to order the SST20 in 4K I can’t wait for the E21A version. I have no self control when I’m bored at home.
You got the will power! Hold back! Lol.
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.
I think the XHP50.2 yellow + green double tint is not pleasant to look.
