Is this better for throw with XP-G, is there really difference between a XML and XPG reflector ?
its one of two xp-g c8 reflectors I have for testing, I’m just waiting on my c8 arriving
I can report back but I expect a smooth beam rather than a throwy one
The CNQ XP-G version needs to be opened a little.
Using a dremel, I opened the hole of the led so now it sits on the led pcb.
I can’t really see the point of that, optically at least. None of the light is going to hit the outermost part of the reflector other than light reflected back off the lens. Perhaps it’s intended for lights with narrow throats and wide lenses?
It won't improve throw, but will reduce spill. I'd bet the actual reflector surface is pretty similar to the dimensions of a P60 reflector, which just leaves one question: why not just use a P60 instead of a C8?
Definately be cautious with this reflector I tore the dome off of two emitters messing with it.
Exactly.
The reflector “hugs” the led dome tooooo tight.
That is the reason I opened it a little.
I just found this thread.
I ordered one of these a bit ago and just installed it in a Convoy C8. When I ordered I was pretty sure it said XP-G, but when I went back to check, they were no longer in stock.
I don't know what yours look like, but the emitter hole in mine is minute. Even half an XP-G wouldn't fit in it. I decided to go with an XP-E. Even that is pretty snug With an CREE XP-E2 R4 1C on a Noctigon and copper pill running at 2.1A the beam profile is nice and clean.
I'm not sure I care for the R4 1C though, kind of yellow green. I can live with it though. Maybe I'll try a different lens. Some lenses can affect tint. The spill circle is perfectly round and even in brightness. The hot spot perfectly defined close up, but softens with distance because of the OP finish.
Not bad. I think I'll keep it in this light.
Yikes!!! It's not really that green. Wall shot with an ipad from a couple of feet. In real life, the hotspot is half the size...or smaller.
From farther back. Really, it's not that green. Cameras do lie!
Ill have to take it out in the wild tonight along with an XM-L C8 to see how it does.
While I was taking taking these last two pics, I could see a definite green tint. I'm going to try a new lens. That dark green o-ring can't be helping either.
Nope. I tried a new AR lens and removed the green o-ring, and it’s still green. I haven’t heard anyone else complaining about the XP-E2 R4 1C, and it seems to be the only bin available.
I put some XP-E2 in a Carlco triple and they have no green. I don’t know what bin they were. Could it be the reflector itself?
Don’t know why you’re getting the green shift but I like the beam profile.
If you opened the hole up to XM-L and use one of those XM-L to XP-E/G adapter rings would that work…and I would LOVE to see that in an XM-L
…so, it’s actually a small reflector, with an outer rim that doesn’t do anything except making it physically wider…?
I’m really liking this reflector. I had it out last night, and the tint is more at home out in nature. You can see that the hot spot is smaller than XML and the beam narrower coming out of the light. The spill is immaculate. A completely even circle with absolutely no variation from center to edge.
The outer rim is not flat. It cants downward. I once read somewhere about how the physics of this dual-stage system works, but I forget. Side by side with a standard XML reflector, the beam profile are exactly the same diameter, but the spill in the Dual-stage is more perfect. Mind you, one is OP and the other is SMO. Smaller hotspot, but one is XPE vs XML.
If I could only correct the tint. Is it possible I got a faulty emitter?
I believe this reflector was mislabeled as XP-G, and is made foe XP-E and smaller.
Can you at all see the emitter reflected in that rim and from what angle ?
The angle looks so off, from here it looks like the light form the LED can’t even hit that rim…
EDIT:
I made an illustration:
You see, that outer piece can’t be doing anything in my perception…
I have absolutely no idea. I just saw it and bought it. I’ll leave the mystery to the scientists.
I finally got back to this emitter and reflector.
The description at CNQG was dual stage XP-G reflector. All I know is an XP-G would never fit. Upon removing the reflector, I found my XP-E2 was crushed, explaining the green tint. The emitter opening was even too tight for an XPE.
I reflowed a new XP-E2 R4 1C and opened up the emitter hole with my dremel. Not too big, just big enough to fit the emitter.
That did the trick. No more green. Nice small tight hotspot. How the beam profile would compare to a regular type C8 reflector with an XP-E, I have no idea.
I like the narrow beam. I already have a bunch of C8s, and I hated the OP reflector that came with this convoy, so I'll keep it this way.
