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.
I have several Crelant lights (5 or 6) and have always considered them of good quality.
If you can get your hands on 7T40 with white flat you can get a really good small form factor thrower light.
Not seen that one, but it looks pretty similar to the V6CS that i just grabbed with the SCH86 head basically a small version of the one above the stock driver also puts down nearer to 3.5A which is nice
I have this one in C8+.
If you shine it on the wall you notice that led is rectangle and not square but I also have the one you mentioned just didn’t put it in the host.
In a flashlight build almost certainly yes. Led4power found a maximum at 6A but it was a bare led with maximum active cooling. My bare led test did not even find 6A max but 5A.
So my best advice would be 4.5A, in a very well cooled build maybe 5.
I’ve found no detectable gains after 4.5amp for either CSLNM1.TG or CULNM1.TG in a flashlight, neither turn angry blue nor do they get any visibly brighter to the eye either IMO you’re just wasting amps after that point
There maybe a VERY TINY increase between 4.5 & 5 in a chunky host like the L2 with a CULNM1 but im not sure if it is just wishful thinking on my part
A lux meter may say different but you certainly won’t see it with your eyes
Edit: Having now taken some lux readings it appears i was incorrect while CSLNM1.TG does not really gain beyond 4.5-5A CULNM1.TG definitely gains up to 6A
