LED test / short review - ChangDa SFP55 6500 K 70 CRI - hardly any extra power compared to the SFH55

Coincidentally I did a quick measurement at the tailcap (end) of my FT03S yesterday, with an almost full EVE 40PL, 14AWG wire and clamp meter and measured a peak of 23(,06)A and then it hovered around 21,5A for about 5 to 10 seconds, at which point I stopped the measurement.

I still want to do a few mods to it, to eliminate as much resistance as possible. For example: the driver wires to the LED look on the thin side. (I haven’t opened it on the driver side though, to see if I can spot which wire gauge is used.)

I missed these posts.

A while back I modded my FT03S and bypassed the springs in the tail cap. That is worth doing.

Measuring mine I was getting 25 Amps using a thick wire and current clamp. Then I cooked the driver somehow- so I swapped in a Convoy 25A driver. It required some filing to do it and I lost the on board USB charging. IIRC the current was the same with the Convoy driver. FT03S driver burnt smell - button lit red. Replacement (improved) driver options 30mm.

If you pull the stock driver out it looks really poorly made.
