I'm more than a little confused. I was shopping for a budget 1x18650 XM-L flashlight and discovered dozens of models that had various lumen ratings. Some were listed as low as 300 while others boasted as much as 800.
What I want to know is: Doesn't the manufacturer have an official standard of what voltage and current range a given emitter will tolerate -which I would assume produce an optimal possible lumen level?
Can anyone explain what they know about emitter ratings? For instance is the "max" for an XM-L emitter something like 3.0A at 4.0V?
Other than the heat sinking - what else goes into limiting the power of some of these flashlights? Why aren't all XM-L's about 800 lumen?
I humbly await a deluge of data.
Sincerely,
