Good stuff Yokiami!
edit: YokiamY :p
Looks great, and I’m jealous! Have fun to night, it is dry now 
Yeah, i’m jealous already for your GT4 
Awesome mod, yokiamy!
Wow, that is some modification.
And the best part of it (for me), it is hardly visible on the outside.
It is like a wolf in sheep’s clothing.
But since the original GT was no sheep at all, one might call it a dragon in wolf’s clothing.
But to be honest, there is a vital thing missing: beamshots.
For the proof of the pudding is in the eating.
Which brings me to another (food) expression: you can’t have your cake (GT) and eat it (GT90).
So you definitely need an other GT for a side by side comparison.
Just so happens that you have one for sale?
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
