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.

In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

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…

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

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?

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 Thumbs Up 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
AlexGT

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: http://budgetlightforum.com/node/60564

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.

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

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 Silly
Either way 1 board please.

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

With a bit careful centering and if you are willing to drill new holes it is possible to get also a 25mm LED board fitting in the GT like I did with a CFT-90

I also have made a new driver with lastest development in way more efficient P-Channel mosfets utilized

note for GT the center viases on spring pad taped with Kapton

Today I sliced sanded and polished 3 MCPCBs for GT and this emptied my stock on boards and LEDs for now

The kit should include the MCPCB with the XHP70.2, driver and the centering plate.

PS. Another option, for those who have few skills, the complete light engine assembled.

Sorry for my bad English (gogole transtorla)

Unlike the buck driver that can maintain constant output until the voltage drops out of regulation, the FET version will taper off the lumens as the voltage drops. Same as all direct drive lights.

I’m thinking the GT host is just a bigger version of the L6 and I have a similar setup in an L6 (a lot of us do). The stock GT with 35w output will get hot, but can handle the heat without stepping down. The FET setup is closer to 120w. I’m sure it can handle the heat for several minutes. Maybe 5? Probably not more than 10 min. I’m just guessing here. It’s a crap ton of heat, that’s for sure.

Maybe VOB can give us a better idea of how long it can maintain turbo before needing to step down.

I just finished modding my GT using the TA GT driver and an XHP-70.2 P2 Led

I LOVE THIS (expeletive) LIGHT!!!

Here are some pictures I took comparing it to my other throwy flooder, the Acebeam K60 which is using a XHP-70.2 P2 Led, the GT totally Pwns it.

Left Acebeam K60 on turbo, right GT XHP-70.2 on turbo

I did not want to unsolder the brass button of the original driver so I used a belt sander to make a copper button out of a sinkpad MCPCB it is 11 mm in diameter and 1.54mm in width

I used 18ga wire, BTW here is the correct wiring.

The lights works fine but I have this problem, when I turn off the light 2 dies stay on and the switch leds don’t light up. they do work since I see them blinking when turning on or off the light, I think the modified SD75 MCPCB might be bleeding some current to those dies instead of the switch, hopefully TA will offer the proper MCPCB’s

Life is good!!! Cool

Alex, what driver is that exactly? Did you switch to a FET as opposed to resistor modding the stock driver?

Is TA selling FET drivers for the GT or is it from Lexel?

Price will go down a little to 22$ per driver

AWESOME video as always VOB!

My question is…. for someone not adept to do a mod like this, can you mod my light for me?

Also, any idea how this mod compares to Vinhs CFT90 as far as performance goes?

Thanks much!
