Thinking of putting a 1mm Osram White Flat in my Eagletac M30LC2-C flashlight.
Do you have any idea if this will work well, and how much extra throw I would get from the light?
XP-G2 output is rated at 1280 lumens, so I suspect each LED is getting about 1amp of current.
it was the xm-l2 version from jax store on ally, the beams are focused but my camera cannot capture it properly ill try again with them on a lower brightness
Unfortunately not, i have transplanted the white flat in a convoy L21A, which now does over 500 kCd @5A
At 1m the hotspot on a white wall is 8,5 ~ 9 cm
I have an L2 & C8+ with the higher power CULNM1.TG and 6a led4power drivers… Sure they are Bright but both of my aspheric setups eat them for breakfast using the same emitter/driver combo
Im pretty sure neither are 500kcd , as i recall Djozz & others only got beyond 500kcd using wavien collar’s
Isn’t 5m a bit short for measuring lux in throwers? I don’t have throwers, but I always see people on BLF saying throwers in particular need a lot more distance to collimate the beam.
The problem are used light meters which may vary a lot in performance and react differently on different tints. Djozz wrote a lot about that.
Larger diameter zoomies and reflectors should be measured on greater distances as you told but for regular lights (50 - 70 mm head) readings should be quite accurate if meter is accurate even at 5 meters.
If you have one of maukka’s calibrated lights (he sells them), he also includes the lux measurement. I asked him and he says he places it on a mount 1m away from his lux meter. So you could compare your lux meter to a calibrated light at 1m too!
My lux meter reads 3% lower than maukka’s readings.
