Show us your beam shots - XHP70, XHP50, MT-G2 - for comparison

look at the bright side. You didn’t refer to her as his dad :stuck_out_tongue:

Just a bump as there must be a few others out there who have shots of this led along with their thoughts on the reflectors used..

I tried an XHP50 in an OP P60 module. The dark spot in the middle wasn’t terrible, but the whole thing was too floody for my taste and it got too hot too fast (even with all the P60 heatsinking tricks). I disassembled it and am working on moving the ’50 to a light with a larger reflector and better heatsinking. Sorry, no beamshots of the P60, but hopefully I’ll get some of the new build.

WOW. Just plain WOW. Love those pics.

For what it is worth in this thread: I made a S8 (my favorite Convoy host now :-) ) with a XHP50 (with a 17DD with zener mod), and the beam is acceptable but not that great. I put an extra spacer between reflector and led to make the led sit deeper below the reflector. Next tweak will be the other way around: bring the led further into the reflector than normal. I think in the end it will be a pretty ok beam, but very floody of course.

White wall @ 5m with flashlight on low, and underexposed to show the brightness drop in the center.

The tree is at 25 meter.

The output was close to 2000 lumen at first but it dropped to about 1000 now, I think I crushed one of the (18350 IMR) batteries, it is bend inwards at the underside :-(

Subbed - still waiting on parts for my XHP70 lights…

Thanks djozz. The shadow looks a bit like the DST. I'd consider that not to bad and I dont notice the shadow at all outside using the light. The best I could get it with the XPH70 was to have the reflector slightly of the star.

Thanks djozz. The black hole in the center, or the black X of death, will be a challenge, just as the spots in the MT-G2 are. I didn't post photos of the monster light, because it's so bright, you just can't tell anything. It does have artifacts in the beams. I am hoping to be able to do a Maglite, with the LED Mag reflector next month. I think the adjustment of the Mag reflector, by just turning the head in and out, will tell a lot about what can and can't be done with these leds. I know with the MT-G2, the beam can get very clean with the reflector all the way down on the star, but I see that it probably won't be the same with the XHP series. Just like the old P7 leds were. Artifacts were still there, however minor, no matter where the reflector sat.

Thanks to a totally willing and helpful do I look like I have nothing better to do Mrs Moose pushing the camera button I have taken some more bad wall pictures with this KD reflector belonging to pinkpanda3310.

The star was filed down and screwed to a stick so the bum of the reflector could sit flush with the bottom of the star and moved out for different focusing. I apologize again for the crappy pictures.

The KD reflector sitting on the stick.

Bum of the reflector sitting flush with the bottom of the star. The hot spot is at its smallest and the the odd shadows is more than likely me holding the reflector slightly of square. It really is a crappy beam regardless. The hot spot is bottom left.

With the reflector held about half way up the star the hot spot gets larger and the spill gets smaller.

The bum of the reflector about flush with the top of the star. This is about as good as it gets keeping in mind there is a shadow developing in the middle of the hot spot. Would I use this reflector with the XHP70? Not with the limited and totally unscientific results here. This should be revisted though when more time is available and an even more willing Mrs Moose is available.

While I was at it I tried the standard TK 61 reflector. This picture is with the bum of the reflector held approx 1.6mm from the face of the star as the screws holding the star down and wiring stopped the reflector from sitting lower. It gives you a good idea of how the beam improves though the further away the reflector is moved from the led.

This picture shows the stick with an led on the end with the TK61 reflector.

Sorry pp l have been screwing around instead of doing your light.

No problem. Makes me wonder if I should use an xhp70 like I indicated. I have a few leds to experiment with when light is returned.

Be in no doubt the XHP70 has more lumens than MTG2!

i got my XHP-70 in the mail today. now i just need all the other parts to get here lol

Thank you MRsDNF.

I think it's best to say that the large die leds, MT-G2, XHP70, MK-R style, are not for throwers. They are designed to produce massive light in a large area and not a small hot spot. I think that with large faceted, OP reflectors, or TIR optics and the right positioning, we can get fair "white wall" beams, but as usual, once you are outdoors, it really does not matter. You can hardly see the artifacts when you are out in real life. Well, that is unless your real life is just white walls, how sad for that.

Thanks for the beam shots, especially those fiddling with the distance from the emitter.
I wonder how this TIR would fare with the XHP70? It does well with the MTG2 in a Convoy M1. I plan on putting those together but I’m holding out for 4000 and 4500 Kelvin versions to come out.

Which TIR is that?

Sorry, home with a cold and boogers on the brain dull my mental acuity. I was supposed to have a link at the “this TIR”. :~

Here is the link.

Or it was this one. When my temperature comes down I’ll check to make sure. I apologize for the confusion.

Cool experiments with that monster reflector Steve.

The golden rule with the XHP… what ever you do keep it out of focus.
Maybe try smearing a bit of vaseline on the lens like the old school, pre photoshop beauty shot tricks :stuck_out_tongue:

I have high hopes for that reflector in other applications and your sample looks very clean in that photo, did it come to you in perfect condition?
Any plating flaws or hazing?

Cheers

The reflector is pinkpanda3310's. it has a small scratchy type mark in one place but not to bad. The dust I blew out with compressed air. One thing I did notice which may just be my imagination is that the plating does not look like it is super shiny, just shiny.

just out of curiosity and having 2 Z1 hosts here. 1 mt-g2, and this one which is a xhp-70 now. just wanted to see what would happen while waiting on my parts to come to throw together a C8 with a xhp-70.

modes are moonlight 2% 5% - 20% - 50% - 100%. 22mm FET driver with zener mod.

XHP-70 Z1 video

i stole the driver out of my MT-G2 Jax for this one, so if anyone wants a video for comparsion to the mt-g2 i will have to swap drivers.
