It didn’t seem to be quite as bright with the 18650’s but I didn’t put the greatests ones in. Probably some sag involved. I would imagine with a really good set of 18650’s that it would be just as bright.
Well that explains why when I put 20 gauge wire on and used ICR KK 26650’s it was so much brighter. I also de-domed the center emitters so that it had a better throw and the ring really wasn’t bad outside, at least not to my eye. When I sold it I thought it was a great light. But I have a bunch of multi-emitters so I let it go. I wonder what it would have done with 4 Moli cells or the Sony 50a batteries I have now?
after mod the spring for reduce the resistance and test with 5 batteries imr I got 8 amp and the original driver finally get burned
now I must decide what to do, I want run it with 14 leds and 2 batteries in 2s7p configuration but rewire all the leds will be bored and the switch maybe don’t will survive
now I have it with 4 batteries one driver “east-92” and around 4 amp with the leds in the original 5s 3p configuration
for use the east-92 with 5 batteries I think will be necessary add some resistor or the current will be too high
