Volume measurement in professional integrating sphere

We had the opportunity to measure many flashlights in a professionel integrating sphere at the labories of Led Lenser in Solingen, Germany.
Some lights were new, some lights were used, and we did't have the time to measure the lights 30 seconds by ANSI-Standards. Every light was measured five seconds after turning on. So PLEASE DON'T SEE THIS AS A REFERENCE MEASURING FOR EACH LIGHT!

However, here are the results:

Great work, thanks!

Thank you for performing this comparison!

While you state not to use this info for reference measuring each flashlight, I think it is very useful to compare a given light to others with similar-stated lumens.

This is some awesome testing I can't believe I missed it. Very cool.

Varapower 2000, almost 100 lumens more than a Fenix Tk70 and only 1 LED vs 3. Yeah, that's why I have so many of them. I think they are the best LED lights. High lumens is easy in serial, but you get low lux. I'm getting 298K lux from my unmodified Lamdalights Varapower 3 SBT.

Hey, very cool, thanks!

What's the number in (parentheses)? The advertised brightness?
