Thanks for the comment and thanks for helping Tom E and Fireflies with the memory bug. Let’s hope it works and they have the fix applied soon.
The batteries are in parallel. Haven’t seen the switch backlight turn off, other than half of them are off when the light is on or it is in lockout mode.
Half are probably wired to Lexels L pad and the other half to the LS pad. L is the normal mcu controlled pad and LS is the permanent on. This is a new thing on Lexels drivers.
But that’s just it, they aren’t too rosy. Just makes everything else look green, but objectively at –0.0020 to –0.0030 duv on the mid output levels, the end result seems pretty much ideal to me.
A relatively small change, but I’d probably like it better without the AR lens. A bit closer to my ideal CCT, with a bit of extra pink, is a double win.
The difference with vs. without lens is practically imperceivable with a CIE 2000 deltaE of 2.2. Everything under delta E 3 is difficult to notice with the naked eye.
Excellent review once again! Think I do have a potential fix, can't be sure but potentially. I'll be talking to them today.
Still wondering about the lumens. In theory this light should be equal to 3 triples, 1 batt per 3 LED's. I don't know how the path from the LED's through the battery is, ex: thickness of LED wires, etc., quality of springs, but if an equally tested 219B triple could be tested for comparison, it would be nice to know.
3860 lumens means 429 lumens per LED, or 1287 lumens for a FET based triple.
I only happen to have an Astrolux S41S with 219B sw40k R9080 and MTN17ddm FET driver with bypass on the driver and double springs in the tailcap. It only does 900 lumens max (at 0 sec) with a fully charged 30Q.
edit: another point of comparison is a triple 219C R9050 BLF X6 with a FET (h17f driver), it does 1620 lumens at 0 sec, 1560 lm at 30s.
