Raised flat tops? I am surprised they worked at all. You need this much extra height.
And no more than this amount of width.
I bet if you add a little solder blob they would work just fine.
GA’s with a raised ‘flat top’ will not worked.
IF they ‘somehow’ worked once upon a time… they would work again. It would be repeatable.
haha looks like this hobby has failed to illuminate my memory somehow. looks like i remember wrong after all…… oh yeah… i did use GA’s… those with button tops! i just forgot i even had them having used the flat tops most of the time. sorry, false alarm, thanks for the help guys!
Do the GA’s with button top work in the light or is there still an issue with them?
@ R10500…. 
No apology necessary, stuff happens & memory sometimes fails. 
. 
Just glad the mystery had such a simple solution…… 
Guys sorry if the question is basic but do the BLF GT/GT70 take flat tops Samsung 30Q’s.Its pretty hard to find button tops now 
No, they must have button top unless you remove the polarity protection.
The best option is to just solder blob the cells in most cases. This is what I do to mine.
I guess I will do that or I read I can buy and put little magnet on the positive side.I cant find any 30Qs with button tops Maybe all are gone cause the users of BLF GT bought them all ahhaha 
Here you go… Samsung 30Q Button Tops at Liion Wholesale. These are genuine cells and the Button Tops are correctly installed.
Magnets suck ….
…. either get the Button Tops or do solder b(. )( .)bs. :+1:
EDIT:… Ooops, I just realized you are not in the USA. Sorry, my bad.
The magnet is only a last ditch effort type of thing, solder blobing is much better.
Danger Bluereldon!
Magnets or any little metal spacer can slip to the side and cause a short circuit.
This is a bad thing.
Don’t risk it.
OK guys I will soldier I can’t find any dealer for button tops who ships to Bulgaria
Thank you so much will contact them!
Since Banggood don’t offer anymore GT70 NW,can you tell me is the CW version too blueish?What Kelvins are they?I am a NW variant fan,but they don’t have it in stock
Post 4 of GT70 thread. I added the tint details myself.
Personally I don’t care for the CW version, it does have a blue tint. Although I will say this about any CW light pretty much.
Some like this though as it gives a “light saber effect”
My personal favorite is a 4000k 80CRI in the GT70.
Is it ’angry blue’…. NO, not to me. I prefer NW 5000K - 5500K, but the CW GT70 is not too bad… to me.
I received my GT in May. I have a couple of issues but just noticed one that is more critical (hardly used it yet):
1. Only one battery carrier works. I’ve been running 4 30Q’s and finally tried them in the other carrier. Doesn’t light.
2. Tail cap only spins with heavy force. I linked a fix to this somewhere when I was waiting for mine. I’ll dig that out.
3. I bought the lens cover with the package. Never received it. Moved a few months after getting the GT. Not sure where to turn anymore.
My big issue is the battery carrier. I’ll eventually get more batteries. Now that my attention is turned back to it I’d like to sort out the rest. Is there any kind soul that can provide some advice?
1. Are all the screws tight in the non-working carrier?
1.a. Are the batteries proper contact on the positive end??
2. O-ring is messed up/improperly installed. Disassemble tail cap & install properly
3. No idea
