Led is a Cree XP-E2 in green. Driver is from Mountain Electronics, just their cheap 1 amp single mode driver, with the 2 amp upgrade of course! It’s perfect actually as the E2 maxes out right around 2 amps.
That said, the E2 (very small die) puts out say 350 lumens at 2 amps, the CSLNM1.F1 is WAY more than that!
Full disclosure, that was in dense blowing snow, it was FAR brighter in that condition.
Assuming peak bin performance that SST is a beast. Best case performance is 1200 lumens in a non converted color! I’m running an XP-E2 that maxes at 400 some lumens and even losing a bunch in a zoomie it is quite powerful.
I made the mistake of thinking it was lumens at first as well, it wasn’t until your comment that I realized it.
Since the light put out is visible I am surprised it is not measured in lumens. I guess it is possible to convert, but its not as simple as a one to one value comparison.
If you could provide the page number for the lumen measurement I would appreciate it. You state it it is there but you yourself stated 190, which min spec is 190 mW. that is not 190 Lumens.
A Cometa (or whatever it’s supposed to be called…)
43.5mm lens diameter vs the UT-20’s 38mm and also longer FL so a tighter beam I think.
It’s a 26650 light.
Oh my bad I guess the units are not in lumens.
There is the section called “luminous flux” on page 3 but instead of listing it in lumens like on all their other datasheets it seems to be mW.
This has messed me up multiple times on this emitter. I’m not sure why they list this in mW instead of lumens. I sure wish those were lumens as that would be fantastic for a narrow bandwidth emitter.
