What bin XR-E and XP-E are you using? I’m wondering how much of the difference is from the emitters themselves. Or, possibly, the difference in emitters could be working the other way, depending on bin, so the difference from the reflector set-up might even be more than shows in the pics!
I have no idea what bin those LEDs are.
The XP-E is from a SingFire 348, so probably nothing special, The XR-E is how i bought the Jacob.
I was assuming it would be similar enough.
Dang, camera battery empty…
I’m trying approx. 20 meters now, but either way, this thing does a nice job throwing in the good direction, but a better reflector would have been considerably better, i think…
The spot @ 10 meters is approximately 50 cm in diameter.
This is a compromise between collimation and focussing, it’s “the best it can do” so to speak.
Hmm, when you put it like that, i guess it’s not too bad.
No i don’t have a lux meter (yet)
I thought i’d compare it with a known light: the Jacob A60.
The recoil setup seems to outthrow the Jacob hands down, which is not bad either.
Hmm that's alright I guess. Maybe look into buying one in the future if you're into flashlights a lot, I got one for $50 a while ago and it has been extremely useful.
For myself, I also contacted a company that makes real reflectors, and it's like $700-1000 for a nice 16 or 20" reflector xD a bit pricey!
Yeah, you’re right.
I thought it was like 120° but it’s actually 140°
This may explain why it does considerably better (lumen / wise) than the A60.
When my camera battery is full i’ll do some shots from the screen towards the LED, hopefully it will show how much of it is actually doing the good work.
It seems the outer perimeter of the reflector is a little ambiguous though.
The contest everyone is talking about is the Annual Scratch-built Flashlight Contest which has recently closed for this year, and winners haven’t even been announced yet.
