His prototype had the thermal regulation set to off by default. It could of been changed in the menu as well but re-flashing ensured it was like the production lights will be.
Steel shows a Uni-T clamp meter on it, out of light, making only 3A on a GA and less than 3.5A on a VTC6, pretty lousy. Should be doing closer to 6A on that C6 and around 1500 lumens or more.
If that’s all that driver can do I’ll have to wipe it and build an FET+1 with the more standard components. Should be able to see over 1700 lumens in the assembled bypassed light.
That’s if, of course, I stay with the XP-L emitter…
The wires are about 50x too long in those pictures as well and causing massive voltage drop.
In the light the readings will be much higher. I can take some on my light if people want but it is using a NW LED I swapped in instead of the stock LED.
The driver is the same as any other FET driver, the only real change you could make outside of spring bypasses to get more power would be swapping the FET for a lower resistance model. Although the one they are using is not bad.
I’m thinking the driver spring is the real (POS) problem, probably using a XP-L HI V2 instead of a V3. I have only found and used the V3’s in 1A and 1C, I don’t know of any Neutral Warm V3’s only V2’s.
The MOSFET is an Infineon, BSC009NE2LS-DS. I use the same FET, no problems getting over 23+amps with it.
Technically it is a 22.5mm driver but it is press fit and needs to be lined up with some bumps in the edge to work, so I would not plan on swapping drivers, piggybacking is a more practical option if that is needed, although I don’t see that working out real well since I doubt a buck driver would fit.
That is unless someone makes a driver just for this light.
