Anyone think about changing the color of the switch LEDs? I think one of mine isn’t working properly and would like to fix it but while i’m in there maybe I could change the color?
Changing the switch LED’s is fairly simple, They are either 0805 or 0603 SMD LED’s and you can use any color you want.
I’m sure it must have been answered somewhere but i can’t find it, is the button cap retaining ring pressed in or threaded ?
Thanks 
Threaded.
Thanks TA, that’s good news.
I have opened my flashlight by 2 people (my son and I) using non-skid rubber gloves.
With the stock Led obtained 925.000Cd. I have replaced it with a boiling thinner dedomed XHP35 HD and now I achieve 1.186.000Cd.
The Led I used was removed from a Haikelite MT02.
The measurements are at 10 meters. At 15 meters I get 1.118.000Cd
Nice! :+1:
Will you do any engraving or modification to the anodization?
I recently saw your Utorch… :heart_eyes:
I am waiting for a single carrier “shorty” tube. I carry the GT right at the switch area so balance is not a problem. A little less weight and smaller overall size would be nice in my opinion.
How many lumens does the light produce?
No integrating sphere. I’m sorry.
Visibly more lumens than stock.
Neither of those two distances is far enough to get an accurate reading.
Thank you, goshdogit.
Emiter swap is so little mod than I don’t plan to engrave nothing.
You might be right, but with a second measure (15m) smaller than the first one (10m), I have interpreted that the beam was already collimated at that distance.
In any case, my luxmeter is very cheap and crappy. I want to think that the actual results are better.
if the further measurement is lower your beam is either not focused to infinity but rather to something under 15m or your measuring method is off
I emailed them about them and they asked what were they for, I answered honestly and they just ignored me afterwards… :rage:
How did you convince them? Got a spare you could sell? :money_mouth_face: 
I am working on a CFT-90 driver for GT
TN42 design finished
Ancient Chinese Secret…been dealing with Lumintop for years, I did a SD75 XHP35HI and needed Smooth reflectors, they made them for me. I sent pics and written details of the builds, the rep at that time was Will, he thought it was very Cool. I guess I’m on their Cool list? A shout out to Convoy, Thrunite, and Phoenix they are great to deal with also, at least on my end.
@ Lexcel
which input voltage?
carrier mod necessary?
I would like to mod my GT with an XHP70.2, someone can kindly tell me which resistor to replace on the original driver, and possibly which value to use?
Thanks.
I have posted this information before somewhere.
You need to replace the 2512 3W resistor with either a .050ohm or .040ohm. The .040 is not officially recommended but it has been working fine in my light for months now.
The biggest issue is the xhp70.2 mcpcb, they are hard to find.
I am trying to talk lumintop into making a batch of them and I think they might do it. Although time will tell for sure.
