Why does the first graph show a stable output around 600 lumen and the second around 300 lumen. I see you talking about a lower configured temp but does this make that much difference? I know the emmiters are not yet decided on so it is theoretical (hoping for xpl hi). I am just curious what would be realistic stable max. output for this light. I know there are to much variables to give a good answer. But I think 300 lumen is not very impressive for a 18650 light (but I still would buy it).
I don’t recall the exact test conditions, but I think I set the limit pretty low on one and didn’t point a fan at it, while the other used defaults and had a little bit of air moving past.
The sustainable level really does change quite a bit depending on your configuration and environmental conditions.
