I said the XHP35 blows the other LED’s out of the water, that does not factor the driver into the equation.
The reason the XHP35 single cell lights underpreform up to now is that they all under-drive the XHP35 by a fair amount. The highest output boost driver I have seen was something like 1.25-1.5A output vs the 2.5-3A we want.
There are drivers in the works that will be able to do this but they are not ready yet.
I can get some readings but I swapped the LED in mine to a NW LED so it would not necessarily match what would be seen in the production version since the Vf varies among the LED’s.
If people really want to see I can check though.
I did test the lumen output before I swapped the LED and with the new TA sphere it read a bit over 1200 lumens.
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…
