I was just thinking...
Many users test at least batteries, tailcap currents and such, some measure lux and total output.
LED tint is always a topic, that gets many opinions.
So, has anyone tested or observed LED spectrums? How did you do it?
The Ledmuseum has equipment to do it, but I do not believe that he has tested any of the never leds, mostly he tests cheap junk these days.
