Don't worry bout any of that - you are free to publish it, improving it, of course, would be nice .
Regarding the ANSI/NEMA FL1 standards, currently it's the 2009 standards and the likes of SureFire, Fenix, EagleTac, Olight, Klarus, NiteCore claim they adhere to those standards. I couldn't find Sunwayman or JetBeam referencing the standards. I haven't seen this debated much at all. Occasionally, for sanity sake, I'll test a name brand light and I find I'm pretty close. Last night I tested an old unused Sunwayman C20C and my tests in my PVC tube with the old calibration scale of 0.34 produced lumens lower than claimed, my reading on turbo was 585, rated at 620. Out of the 6 brands I listed, only one I would definitely not trust is NiteCore, since their market hype is through the roof. Zebra mentions ANSI OTF, but that's not specific enough. I know I've seen manufacturer's showing off pics and reports of their very expensive integrating sphere, but somewhere there seems to be a dis-connect. There is only one ANSI/NEMA FL1 standard, not two, and if there is an industry higher lumen standard, we shouldn't sit idly by and simply accept it.
I've confronted manufacturers before, like ArmyTek, but just checked their website and I guess I didn't influence them. I thought they went out and bought an integrating sphere and were going to do it right, but I see they claim "LED light output, lm", whatever that is, and no mention of ANSI/NEMA FL1. ArmyTek is an easy one to go after: claim is high tech, top scientists and engineers, world's first technologies, and they can't afford and figure out how to use an integrating sphere, and comply with the only world-wide industry standard governing flashlights?
Every manufacturer website should have a page on measurement/testing methodology and give us an idea of what they are doing - calculated from specs, milk carton, or $10K calibrated integrating sphere, and their methodology in using the equipment.
