The XHP70.2 8,000 Lumen BLF-GT With Beam Shots!!!!!!!

In this video I show the awesome superpower of the XHP70.2 in a giga-thrower. See how to swap the emitter and boost the driver current.

5/20/18 Update

To answer the question about sustainability I did a test with the final version of the light from turn on to 90 seconds. The output is quite stable because of the large copper mcpcb, however the light does heat up very fast. I took the temp readings on the lowest part of the “neck” piece. I would say realistically at 60 seconds you should power it down, by 90 seconds touching it gets a little sketchy.

Speaking to the “dark cross” issue. I know others have said their reflector created a dark cross using this LED. I tried the reflector from my first batch of the group buy, as well as the two that arrived recently and did NOT get this from any of them. However, the second two reflectors were not tested until after the dome of the LED had been removed. I also tried using 2 other thicknesses of isolator with the reflector I used in my video. 2.5mm is thickness from the factory, so I tried a 2mm and a 3mm. None of these produced a dark cross, but they did seem to effect the corona and hot spot a little. At a quick glance I would say that the 2mm one reduced the corona, and the 3mm one increased it.

A final note. While I do take care to produce the most accurate number sets that I can be aware that I am working with a brand new light meter which I have only spent about one hour calibrating my system to. Six lights from preferred sources were used, but fine tuning is still needed.

I need these parts!

Superb video. Very entertaining and easy to watch, and at the same time very informative. Kudos and thank you!

Nice build and great video, thank you. I have basically the same build (XHP70.2, TA 3-channel FET) in a Convoy L6 that I like a lot, but the focus this larger GT brings to that build is really something else. I may be tearing into mine…

very nice tutorial.

thanks man

I have the same build in my L6 as well. It is amazingly bright but the GT makes an awesome host for this combo. I think that’s the main reason I got the GT

Same… I want to do this too…

Awesome video and good discussion at the end. I hope we are able to get this mod soon. It will be really interesting how this compares to the much more expensive Luminous.
Do you have any guess what the Lumen output would be prior to the dedome but with the mosfet?

What’s the lumen output over time with the mosfet driver? Can the GT host handle the heat?

great video!

Will the LED run on full power with the short tube? BTW I love your videos! :smiley:

This will definitely require VTC6’s or 30Q’s either way!

Thank you for another awesome video :beer: This is exactly the mod I plan to do over the weekend, What width shim did you end up using for proper focus of the XHP-70.2, did you have to change it after dedome? I like the DIY tool you made for dedoming the LED without removing it :+1: What width is that metal guide you used for cutting the dome?

Can’t wait for my XHP-70.2 order from MTN to arrive today…!

Thanks

Very impressive results. I rounded all my prior numbers down as I was worried they might be unreasonably high. Good to see that someone else got even better numbers.

Also, some of the difference in the readings can be attributed to the tint. I as well as others have noted rather significant differences in readings when testing LED’s of the same bin but with different tints. Sometimes as much as 10-15%.

I just posted the drivers for sale here: Texas Avenger Driver for the XHP70.2 GT

The mcpcb’s are still unknown. I think lumintop will make them but no idea when.

Till then this sinkpad should be able to work with some sanding of the edges:

Although I would not use it with an 80cri LED, they pull too much current and I would worry about them overheating on the aluminum.

In for 4* xhp70.2 mcpcbs :smiley:

I would be fine with that. I got an MF04 on preorder, that’s why I’m asking. :smiley:

I’d definitely be in for an led and board (if sold together) would be even better if we could somehow order a ‘kit’ with the resistor, led and board…… wishful thinking maybe :stuck_out_tongue:
Either way 1 board please.

A kit is what I have had in mind from the start. :wink:

Nice one TA :+1: You da man! :sunglasses:
Oh and forgot to thank VOB for another great video! Cheers man!

If there’s ever a kit available I’m totally in for a set
