A quick comparison Z1 7g5cs L2 & 1 Zillion candela Lumen Ebay HID (the Chinese seller says)
It’s a little misleading the 7G5 appears larger because the Z1 has far superior AR coating,
the glare makes it look larger and camera is struggling to pic that out
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.
