badtziscool, thank you! It's just 'universal' topology: it may connected as 4 led in parallel for buck, 2 parallel x 2 serial with boost and may use pair of led for dropping exceed voltage with simple linear regulators like AMC7135

Now I'm waiting for optic for build first flashlight with it

That's what I was thinking, but was there any reason to design the top middle connection point in that fashion? It almost looks like it was masked out for an led to be put there. Looks really good though. Nice to have options. :)

Oh, I understand

Here's the point: flashlights produce a lot of fan for me so I always try to add some kicks back

It's Chinese trigram 'fire'

I'm going to get about 2000 lum from it, so 'fire' look like good joke. For me)

BW, my parallel triples looks kinda masonic )
