From the pics of the beamshots, green looks like the best thrower, which makes sense from the NM1 specs and other tests/rating comparisons of the white and green.
I wonder if the sensitivity of the Lux meter being used is also going to influence the measurements. I have no idea how different colors will be interpreted by it.
This also explains why car fog lights are yellow. They are not allowed to be red, green or blue, because of the traffic lights. And they don’t want all kinds of different fog light colours in the traffic like pink, cyan, violet, turquoise etc. Therefor the improvised standard for fog lights is yellow (3000K). So for a flashlight to be used as a fog light outside the traffic, red, blue and green may still be the best, as these correspond to the red, green and blue receptors in the eye.
djozz - is the OP still accurate? Another words, the green LED could be driven at it's max of ~7 amps and without issues?
I was thinking this, and the 4.5 amp NM1 drivers everyone wants for white is not desirable for the green version, if you want max amps and output of course. So this further confuses the lumens and throw of green - clearly at the same amps, it's better, but compared at their peak amps the green is way better. Then again, looking at lumens, the difference from 4.5 amps to 6.5 amps isn't that great really. maybe ~10%
I assume it is accurate. But I always test one led. This was a sample that came directly from Osram (via TheOnlyDocc) but I see no reason why it would be any different from the ones that are in these flashlights.
What kind of battery are people using here? On Banggood there is the option to buy with a Samsung 30Q (button top) included, so I guess a 30Q would work well. However, if I look at NKON, the Sony / Murata US18650VTC6 3000mAh - 30A has more and better reviews, and has a 30A rating instead of 15A. Would this Sony indeed be a good option for the FT03 mini? And if so, would it make a difference whether I choose a button top or flat top model?
Oh, and what 18350 batteries are people using? On Banggood it only reads that it needs to be an unprotected one:
