Thanks for the reply.
The idea of asking for 5000K is that this provides a little more choice on the cooler side. Just wondering: Is this flashlight capable of its most lumen setting when the color temperature is in the middle, and least maximum lumen when at the extremes (2700K and 4500K)? Perhaps only 2 emitters are on when at the coolest and warmest? I think lumen vary slightly due the 2 pair unique LED efficiency but to my eyes the output seems quite stable. Its mostly the temp that vary leading me to believed the sum of current across the LEDs is constant and only the 2 pairs current level exchanges to vary the temp. This postulate can be confirm if we measure current accord the 2 pair of LEDs and see the changes in real time.
You can post your PayPal here, put an LG cell or another 18650 you think would be better, and the total. I will send the $ to your account (with notation of what flashlight I'm buying).
Put in the 219b 4500K. That's fine.
It would be nice to see a quick demonstration video showing the different temperature options. This needs to be done for sure. I just need to find time to do the video. I have so many videos I wish I have time to do haha
Maybe you could have your boy as an example of skin tone with the variations, on the flashlight before you send it to me.
May be I will do a video showing stock setup and one with SST20 2700K + Nichia 219b 4500K to see what we get.

When I first saw that title, I was thinking thermal adjustments, not color temperature! I'm kinda stupid though.. haha! For some reason, it never really occurred to me that this could be done. In any case, yeah that's quite interesting! I can see a whole new off shoot of photography lights based on this concept.
