Terrific work on the mod Yokiamy. And to boot it works. Even better. 
I love reading about mods like this where members come together to help another. Nice work all round. 
Thanks for getting the measurements to me, oweban!
Hm, coming to think of it …. :innocent:
Sweeeeet!!! :o
I don’t have use for one of these, but I’ll be happy to see your beamshots when possible!
Nice “community work” 
Great job on the conversion mod! Does anyone know if Lumintop will make a GT90 mod kit in the near future? The GT90 is to rich for my pockets as I am sure for many others.
It’s a crappy phone pic, but ITS AWESOME !
It feels like firing a bazooka (at least, that is how i’d expect it to be, i’ve never really fired one)
I felt like a deer hunter (spot the deer)
That looks amazing! The spill and beam are incredible 
That’s a nice community effort and result.
You can gain more output if you take the lens off STB90.2. Vinh54 has a how to guide
For anyone that might be interested in doing this mod, I would recommend doing that yokiamy did and using the Gerber files he linked to over at JLCPCB or PCBWAY. I like Oshpark but for larger boards they can be expensive. But if you’d like to get a view of what the boards look like, here are Oshpark links:
Nice, what was total build cost?
100€ for the GT, driver and mcpcb with SBT90 65$, PCB’S for the carriers were 6$ (+ additional shipping costs)
So around 180
Looks good and well done. That’s the cheapest GT90 ever!
Impressive :o
The deer must have thought he was going to be abducted 
” yokiamy ” Very impressive !! You guys are showing that ” Old Lumen Spirit “, just what BLF is all about. Nice to see TEAM work

There is something about a ” hands on modded light ” that is so much more fun to use. Enjoy 
Very nice Yokiamy! Thanks for sharing, must be fun.
Great mod

Excellent job on the mod!
I converted 2 GT's with the kit, have 1 more kit to go, but still need to upgrade 2 more GT's after that. Just emailed Lumintop if they would sell me two sets of the driver and LED/MCPCB, so waiting patiently for them to respond. If they are able to sell me the parts, I'd be very much interested in downloading the Gerber files for the carrier boards and getting them made, maybe with OSHPark but I may give JLCPCB a try. I'll have to price compare - OSHPark is probably a bit more $$$ but free shipping.
JLPCB for me, with shipping, was $12.06. However, there were several options that I couldn’t select for the boards at checkout. It would give the same warning, that the options selected were an uncommon combination, and they would have to do a custom run, and it would both take longer and cost like $30 extra. So I got everything default except red solder mask on the positive and black solder mask on the negative (those options were free).
It’s also worth noting that it got me like 5 of each, and I only need one of each for my mod (MF02), so I could send a pair of each to someone for the cost of shipping.
What did you do about the driver and LED?
I’m putting a TA 46mm FET+1+15 SRK driver in my MF02 and I got the SBT90.2 from Hank.
Sorry I don’t have any ideas about the GT driver. All you really need is something with a FET in the correct size, though. No idea what the size is for the GT. I was curious about the GT90 driver itself, but Yokiamy didn’t post any pictures of the topside of the new driver
