Re: Actual Lumen readings from my integration sphere
One thing I have found very interesting - is the extreme difference in perceived brightness vs what the numbers say. I have always known this was the case in theory - but its another thing to see it first hand with concrete numbers.
Lets look at 2 examples:
Convoy S3 3x XPG2 R4 5A1 - highest mode 1414 lumen @ turn on, 1321@ 30 sec (at 5.8 amps) - next highest mode -462 lumen (at 1.91 amps)
The convoy uses a "narrow" optic which blends all the light emitted into one large hotspot (which actually ends up being floody, as far as lights are concerned.... go figure... narrow is not really uh... narrow at all... but I digress)
I had my wife as a second observer and I switched back and forth a few times between the highest and next highest modes (~1300 and ~460). We both agreed
sssh:it doesnt happen often) that the highest mode looked to be around maybe 700 lumens when comparing it the 460 lumen mode (in terms of relative output); when in reality its close to 3x the actual lumen!
Also... the power difference is 5.8a vs 1.9a.... it takes 3 times the power for only a slight increase in perceived brightness!
Securitying King (skyray king clone) 3x XML2-T6 4C with UCL & fet driver
4476@ turn on, 3810@ 30 sec, 1905 high
Again - same thing as the convoy - switching between around 2000 lumens and 4000 lumens looks to be only a 15-20% difference when in reality the highest mode is 100% brighter!
7000-10000 lumens is attainable now. How many more lumen is it going to take to really blow these cutting edge mods we have now out of the water? 40,000? 50,000? and how much power/efficiency is needed?
