Plus a few other sources here and there. I’m trying to figure out what the xhp35-HI is really capable of.
The part about losses is not so clear. I hear a bunch of confusing stuff. Like most reflectors only being 85% reflective and lenses being 97–98 clear. Texas_Ace says that xhp35-HI seem to suffer higher losses than other leds. It’s all a bit fuzzy in my mind.
By light box, do you mean a lumen measuring device like an integrating sphere? I just recently got a JoshK sphere, but I haven’t messed with it much. I’ve also got one of Texas_Ace’s lumen tubes coming my way, as well.
I’ve measured a few of my lights, but haven’t measured any raw leds.
Based on your experience, what are some realistic losses?
BTW, isn’t the TN42 only pushing 2A? The fact it has that much output just makes me scratch my head. Lol
