I am a little disappointed about this light. The light has an orange-peel reflector (it doesn't work well with a smooth reflector, I tested it and got a significantly dimmed center). The throw is much less than my XHP50.2, SST40 and SBT90.2 FT03s. The lumen output seems to be much lower than the claimed 9300lm - I think the required current for 9300lm is limited by the batteries (I tested with Shokli 20/30A 5500mAh and Keeppower 20/25A 6000mAh) and the internal and FET resistances. I already bypassed the springs and changed the LED wiring with AWG18 wires with minimal success. Don't get it wrong: It is a nice light. But in this size there should be a little more throw. Much lumens can also be produced by smaller lights with some emitters. It is more expensive than the XHP50.2 version, and I prefer the XHP50.2 one.

  • pavincicm which battery do you use?

  • pavincicm You should use Samsung 40T and output should be much better, I had Shockli in my ft03 xhp50.2 and switched to Samsung 40T, and difference was abnormal, at least 1000 lumens more than with Shockli, I was amased how much brighter it was with 40T.

  • BG132321910 You`reusing the wrong batteries. Try samsung 40T or molicell 42a.
    The difference is huge.

  • CaptnKnuspa Thanksfor the recommendations for batteries. Now I use samsung 40T (and also replaced the driver FET with a lower RDSon type) but still I'm not 100% happy with it. I can't measure the lumens, but I think I don't get even close to the 9300 lumens.

  • Sharmman @CaptnKnuspa Thisled has low efficiency and requires 50A at 3,5V and 14AWG wiring in order to reach 9000Lm , there is no single Li-Ion battery that can provide 50A and maintain output voltage >3V.
    The best solution is only Samsung 30T for a few minutes.

  • BG253391345 40Twhile brighter, it heats up way faster. This has a good flood/throw with ShockLi already.
