That’s the best $12.18 I’ve EVER spent! (of course I know they were cheaper at WB just a few days later ) I remember posting a thread about looking for a budget thrower when I first got on here and several people suggested it, but I didn’t have a clue. Anyway, after playing with it….I mean, TESTing it last night, it’s a real winner as is.
Is there ONE easy mod to make it better/brighter without spending much money or being too difficult for a fledgling modder?
XR-E's are around for many years but are still notoriously difficult to improve in throw without going bigger and more amps (with all the extra problems that arise with that). If you like pencil beams you could consider dedoming the XR-E, you loose some output but the even thinner beam is more intense.
I dedomed several xp-e2's. Works. Thing is that dedoming xp-e's, xp-g's and xm-l's result in up to twice the throw, I just tried to find data about dedomed xr-e's but could not find any (lots of talk about dedomed XR-E's but no lumen/throw output data could be found), but I think I have understood that the gain from dedoming the XR-E is much less: you loose total output but do not gain a lot of throw. Can anyone correct me?
Thanks for pointing out the paper disk problem, it doesn’t seem to sag but I haven’t run it for very long yet. No dedoming for me, makes them too fragile imo. Where do you get an XPE2 on 16mm copper and how much juice can it take?
Most 20mm can be cut/filed down to 16mm. Just have to be careful not to get a short with the contact pads so close to the edge of the base afterwords. Most of time you have to cut through the contact pads. That's not a problem. If you have to, you can scrape some of the paint over the underlying trace to make a new contact pad.
No xp-e2's on copper (or aluminium for that matter) I'm afraid. I see them only as bare leds at Illumination Supply (I myself never consider Mouser or Digikey because of their shipping rates, but I doubt they have mounted xp-e2's).
Match's data give a maximum output of the xp-e2 on copper at 2.4-2.6A (480 led-lumens). Above that the output decreases.
That should do what you need - now need meter to confirm and for next steps IMO.
Post a pic of the current driver to see if that has an easy tweak while you’re waiting for it. Beyond a tweak or direct drive you’ll probably double the cost of the light with better parts (and it will be worth it IMO).
If you have an XRE in it, then I’d definitely do an LED on copper and driver swap using recommended parts, preferably where someone has posted results. The XPE2 will stay very narrow beam, and be much brighter if matched with good driver.
If you want more spill, the XRE probbly has a fairly big reflector opening, you might want to get both and XPG2 and XML2 to see which you like (if you can’t find online results).
