^ I don't know what is was designed for but when I was playing with mine it focused best above the star.  Check out the portion of reflector not being hit by the emitter's output in the below pic (very awesome pic, by the way) from Post 12. The emitters we use don't emitt 180 degrees and most reflectors are designed for that.

EDIT: My reflector is in storage at the moment, but my recollection was that the curve of the wall appeared to be parabolic all the way to the drop off to the bottom flat area.

Okay, that’s good to know! Thanks! I was just reading the specs from the maker’s website. I’ve played around with mine in open air, but haven’t got to really test it yet with things locked down in place. Wink Could it be the difference in emitters? This reflector was designed for Luminus SST-90, not the Cree emitters we play with around here. I do have a SST-90 I might test it with, when I get a chance. Then, when I get my MT-G2’s I will see where the best focus is achieved with that as well. I don’t have any XHP-70’s to test with, so thankfully Dale has already posted pics for us here! :bigsmile:

^ Sounds like a good plan and I have to point out that I didn't try to open up my reflector's hole to even try the setting in the above pic.  I just got as low as resting on the mcpcb. In the above pic, not much of the reflector is "wasted", but then again I think I had my reflect maybe above the top of the mcpcb by about the thickness of a noctigon. 

I am curious now and will need try that out.  Your point that the reflector maybe designed that way makes sense.  It could be the beam may have fallen into place if I would have continued going deeper into the reflector.  Interested in hearing what you find out.

You can’t go by that pic, as it’s a macro from close range and doesn’t show the focal point. If I pull back from the light the reflector fills with the phosphor color at the appropriate distance.

Remember how a donut hole appears if the light is too close to a wall, but the hot spot is focused at a certain distance? That’s what you’re seeing in that pic. The light has to be collimated towards a distance in space to get the beam out there where we want it. Gathering light from a small point in a large reflector means it takes some space to get the beam to come together in focus. Smile

With a thrower, this can be seen as a dark “^” in the beam, with the point out there where it all meets.

I was going to put one of these in my Courui with an MT-G2, but the Courui’s reflector focuses that emitter into a tighter beam so I left it alone. (held the Lum 5-90 on an MT-G2 for testing)

The diamond profile mixes the light from the emitter, perfect for the XHP70. It blends away the small artifacts in the MT-G2 as well, but with a larger softer hot spot than what the smooth reflector does in the Courui.

^ Good point about the position that picture was taken at.  I should have thought about that  because I have noticed that phenomenon myself when trying to take pictures of my lights.  Thank you.

It’s just that when taking a picture up close, the eye of the camera is inside the “^” and so is not seeing the clear picture.

(man, I just read some quotes from a Chinese vendor and now I’m sound like them!)

For anyone that is interested, this reflector fits in a tk61.

I had to trim the top lip off the reflector, move the o-ring in front of the glass (instead of behind), and flip the pill to bring the led closer to the reflector. This is just to show it fits. The pill in reverse does not have good contact with the body like that.

I will try this mod at a later date. I’m waiting on a lux meter and the tk61 is one of 2 lights I have that are stock and have manufacturer rated lux numbers. So I want to reference that against the new lux meter before modding the tk61 (plus I’m busy at work lately).

You have a couple of very mutli purpose TK61's. Nice info. When is the XHP70 getting a run?

Not for a week or two I guess. I might get something done over easter but no guarantee.

TK61 for a host is awesome, but spendy. Is there a more budget friendly clone or host that can easily take this reflector?

Dale, have you tried the XHP70 in the Courui Big Head?

The multi-die issue in that big reflector would be problematic, I think the Lum 5-90 could be fitted into the D01 but then the battery layout would also have to be addressed.

I put an SBT-70 in one though. Smile So I have a de-domed XM-L2 in one and the round die in the other. Hand polished reflector in the SBT-70 variant, as the silvery coating peeled off the aluminum when I was washing it after cutting the bottom out for the big die. Literally big chunks of both the brass sub coating and the mirror finish coating peeled off.
Water got under it, which means it wasn’t adhered well to the metal.

Thinking about the Lum 5-90 for that one. Sitting on it, trying to get a powerhouse light built for a buddy and it’s giving me fits. lol

4 the record, 3 XHP-70’s in parallel 12V configuration don’t play nicely with 3 26650 Efest Purple cells. Not enough overhead.
