to the first post and pictures, camera settings was the following: 1sec shutter speed, and iso200
And I think my 3xmc-e light is almost the same as the new triple xm-l flashlights, trustfire sky-ray etc..., maybe a little brighter, becasue my light sucks over 3A from 3 pc 18650. I use relative old cells with this light (~150mOhm internal resistance), because of the direct drive. It could be to drive easily over 4A/emitter with newer cells, but I dont want to overstress them.
This google translate helps me alot, but I know it's not perfect. :)
Nice beamshots, nice 3 x MC-E too. Quite noticeable donut though. Surprised that the 5 x Q5 did not throw as well....you got the more recent versions? (only the first batch was driven aggressively)
For those who wants to buy the 100mm diameter 3 x MC-E, can try PAlight BG-03 and XTAR D31 howitzer. Expensive though.
Yeah, it would be better with xm-l -or a better reflector- but when I made this light, there was not yet only mc-e. It's a DX triple reflector SKU11922.
My tr-1200 with 2 cells goes 2.5 ampere, it's ~ 15W or more.
Earlier I made ceiling bounce test, and tr-1200 performed "35" relative value, and the C8 clone xm-l's score was "40" at 3.5A. The throw capability is almost the same for the tr-1200 and C8 clone.
Yes, I have a cheap one from ebay, lx1010bs. I don't know how accurate this. I think it measures higher value than the real (20-30%). I have only relative peak lux values from 3 meters.
Any info is better than no info. BTW do you mind measuring from say at least 10m, preferably 15-20m? What i am trying to do is to let the beam focus and smooth out, when you are farther out the hotspot peak intensity will be easier to get hold of and not only stay at a small place (it smooths out so to speak). Also the meter sensor will not get overloaded, as you can see 24k is too much. Forget about the specs - most guys in the hobby know about the characteristics.
C8 XM-L @ 3.5 is pretty well known. XR-E @ 1.5A with a 44mm aspheric is also guessable. Yours is high but we still can make corrections and give educated somewhat accurate guesses and be around in ballpark.
Your XR-E @ 1.5A with 44mm is probably 55k region in true life (i am expecting decent heatsinking but not excellent, so you get around 1.1A-1.2A true relative performance unless you directly mount to pill). Triple XR-E aspheric is 2.6X, so you get 143k. Could be slightly higher than Olight SR90.
