I’ve seen beamshots from M4DM4X. Thinking if they will sell conversion kits for current stock GTs. Throw numbers we’re at 2.65km and 6k lm iirc.
Edit: is it good enough to just get the led and swap it?

I don’t believe so. The XHP35 is a 12v part; the SBT90 Gen 2 is 3.5v.
You just need a different buck driver from Lexel.

I think if they made an SBT90 gen2 driver and led kit for the GT, mugs like me would do the “shut up and take my $$” thing.
Yes I want that too

Driver is the next hurdle i will do some current tests on the k75 soon
Dunno if any buck driver can go that high in amps. Best thing would be modding the battery carriers for 4P.
You can make 4p battery holders from 2 astrolux battery carriers with no modification
Huh? Ok, you got my interest. Do u mean the astrolux carriers would fit in a GT?
In case anyone is look'n for it, if not already posted, Wendy emailed the SBT90.2 datasheet to me, I posted it here: SBT90.2.
If Lumintop would be interested I would finalize my very high current driver for 3V LED from 2S battery
The head part would be needed to machine out proper parts for thermal pads to get an efficient cooling, but even without that it might be enough to get rid of about 4-5W heat

Ah, but the GT is 4S. Would it work for 4S?
Ive been waiting for someone to approach this. Subscribed!

Sounds too difficult for entry level modders, most people just want a conversion kit (as with the XHP70) driver, mcpcb with LED and different battery carriers for 4P.
Nobody is waiting to machine his GT.
WTB: Jetbeam TCR-1 or Sunwayman V10R Ti
Im not sure the astrolux carriers are 2s2p. At work at the moment when i get home i will measure them
I would be interested in testing them for you in custom made lights with sbt-90 and a cft-90 using GT reflectors i have
It seems the Astrolux carriers are 2S 2P, so you have to mod them
WTB: Jetbeam TCR-1 or Sunwayman V10R Ti
There is no modding if Lumintop would release a SBT GT
4S would need a way bigger inductor size than 2S or current had to go down a lot
At a current like 35A you cant make an easy mod, I bet also the K75 has dedicated heat pads to cool components on the driver
Things get toasty at that high currents even with 95% efficiency

I would mount the driver i something similar to this. Tonight i will take my K75 apart to see how it is done.
2 astrolux 2p2s battery carriers can be made into 1 4p carrier with no modification to the boards.
Grin, taking the k75 apart would be much appreciated. Really, Looking forward to it.
And also, which driver is that in your pic, looks super familiar.

My 3 ordered SBT90.2's arrived today. I got a couple spare GT's to play with. The LED's are a big assembly - no idea how I'll fit them in a reflector. Might be better off in a zoomie for now. I got a couple big zoomies - the 1504. Betta it would be interesting in one of these...
I did dismantled my K75 and soldered some cables between the driver and led to measure current. Results
Low 500ma
Mid low 800ma
Mid high 2.7A
High 5.9A
Turbo 28.7A
How do you plan to driver them and at what current? I have some GT reflectors for scratch builds, a massive triple with 3 GT reflectors would be fun but the power needed would be huge. I have 6 on order and im going to need drivers.
Straight FET or FET+1. Doesn't need anything special. Even the SIR800DP can handle the amps, but I have better FETs. If the K75 can do 28 amps, should be able to match it, or little better perhaps.
That's pretty good #'s. The 1504 unfortunately is designed for a 16 mm MCPCB - forgot bout that, but looks like I could dremel it out to about 19 mm, so might do that. The other high performance zoomie is the Brinyte B158 - I got one with an empty spare brass pill, and that's for a 20 mm MCPCB.
Still a good deal here: https://www.aliexpress.com/item/32831194642.html?spm=a2g0s.12269583.0.0.7e7414fey5MN4W
Cheers I am getting my head around how to drive them, it should be simple enough. I ordered mine on 45mm mcpcb.
This sounds very interesting

Also interested in a beginner mod type option
X70, Blf GT, Kr1vn90, FT03s, FT02s, TM16, Emisar family, and many more
I finished the 1540 mod, details here: http://budgetlightforum.com/comment/1590861#comment-1590861. Not getting the amps I was hoping for, but it's not fully tweaked for high amps - should use a better FET, thicker wires, etc.
SBT 90.2 conversion kits for BLF GT would be fantastic, this would be THE led for this light.
Id imagine its not “if” but “when” it happens. And when it does, sign me up! As tempting as it was, I just couldn’t bring myself to swap for the XHP70 kit and lose out on the downrange concentrated illumination and efficiency the XHP35 provides. I have plenty of large flooders to fill the gap and dont need another. With the SBT90.2 in the GT, there should be no compromise and hopefully greater range with the same useable spill the XHP35 already provides. 8 × 18650’s should provide the perfect economical solution to minimize voltage sag while allowing the host to heat itself to some nice hand warming temps!
The awesome specs for the chunky GT host speaks for itself and is practically screaming for this upgrade. As always, patience is a virtue…
