How long does it take to receive a light after ordering?
I ordered an CW version on 31 Aug and haven’t received any shipping info yet. Is this normal?

That does seem a bit long. Once it gets into the hands of DHL they can typically ship it to your door within 3 business days. The big variable is the time it takes to go from Lumintop to their third-party shipper and then to DHL. This can take from a few days to maybe 2 weeks. Maybe TA has a shipping update.

I would follow his advice here.

I ordered and paid for my GT70 on Aug 30 (Order: #900112870)
I still have not seen it or been updated on the shipping time

They do ship in batches but it is odd that it has taken so long for yours. I would contact Leo@lumintop.com and check on the status.

I did the ceiling bounce tests on the blf gt lights.. I use my olight sr96 and mt18 as a reference since they are measured by TA tube..

Already received a reply from Leo that he would arrange shipment this week and send me shipping info.
Thanks again for the assist.

God I missed these forums!

Someone update me on the stability of runtimes in each mode, please. And what are lumen outputs for the 12 standard modes?

Quite excited for CW version.

Is there any chance to buy a short battery tube for the GT(70) at the moment ?

BG doesnt really show if its available at the moment.

Would be great, to make this light somewhat “carryable”. It would fit into my backpack (sideways) and I would be able to carry this light with me (on tours). I visit bunkers, mines, huge factorys at night and this light would be great for some long range illumination.

This would make the light more useful for me, apart from being an “oversized toy” with limited practical use.

Current Collection:

BLF: BLF-GT90, BLF-GT70 (CW Sliced), BLF GTmini, BLF-LT1; 

BTU: Shocker (3 x SST-40 @ 8A)

Solarforce: L2P (XM-L2 U3 @ 4A), MPP-1 (XP-L HI @ 6A), MPP-3 (3 x XM-L2 U2 @ 12A), M6 (Nichia 319A @ 6A), M8 (XHP-50.2 @ 9A), 9x (9 x XM-L2 U2 @ 2A)

Coming Soon: Lumintop: BLF-GT4;

There are 150 different levels. The run times will vary depending on the level and whether your using 4 or 8 batteries and what type of batteries. That’s about all I can tell you. I’m not sure about specific run times.

I would say it’s way better the BTU Shocker. It can handle 130 watts no problem. The Shocker was only about 30-40 watts I believe.

If you have the short tube it will work with the GT70 but it will also reduce the output as well.

No idea on when or if they will make more of them though at this point.

The white thermal paste is really not that bad in my testing. When it comes to OTF lumens, it made virtually no difference. Heck with enough clamping pressure no thermal paste at all was only a few lumens behind.

Sorry for the misunderstanding.. I measured both olight st96 and mt18vn with the TA tube.. TA tube show 10500 and 10720 lumen… then I use light meter app to get the all the lux reading. That’s the only way I can get good reading on the blf gt lights..

I think he’s referring to that white RTV silicone looking stuff that some manufacturers use and feels rubbery.

The GT (and I assume the GT70) use a proper thermal paste. It stays soft and never gets hard or rubbery.

This is from my BLF GT.

I would so totally be down for this. I’d be in for one more GT and 4 extensions. Or 6, maybe 10. Evil

Well, do you have a license for a photon launcher ASAF?

It would also be classified as a siege weapon.

I would personally try to ram a door with it. Would be so fun

No license. We will need to keep this on the down low. I will only tell BLF/CPF and Youtube about it Smile

Yes sir.. it is not the right way to measure lumen.. i know two lights are measured by TA tube and use them as a reference… the lumen number are pretty good as you can see by my testing.. those are @5 seconds lumen…

Ah, I see. The silicone thermal adheisive is still not horrible IF it is properly clamped down before letting it dry so it is as thin as possible. I have done this in a few hot rods and it works great.

Now in most lights it is used in, they do not clamp the mcpcb down so it is way to thick and yes, then it is positively horrible.

Lumintop BLF GT Flashlight DIY Short Body That’s the page at BG for the shorty tube but go to Martins site and join and get the code under Lumintop and that will take off $5,
$20 is a bit steep to me and I can’t just give out the code or Martin would scalp me or worse, but that price does give me a good clue as to what an full extension tube might cost.
Kind of funny at Lumintop, the secondary Giggle code for the conversion kit didn’t seem to work so I got hold of Victor and he fixed it for me, he brought the cost down to $83 for the kit and two extra carriers,
I have no idea what the discount would be but no matter I’ve gotten a good deal from Lumintop since day one, but then after I paid up it asks if you want to go to the home page and so I did and I noticed right on their home page another code for the GT that brings the price down to $220, ha ha.. wow
I guess the GB might be sort of over with if their advertising a code of their own as well, I can’t help wondering why bother with these codes, just sell the light for $220 and skip the codes, nothing is secret anymore, there’s codes everywhere.
But, out of all the codes I’ve seen TA’s code is the very best so Giggle that..!

51_F4_F049-3906-4_F3_E-80_F0-9_BDA50_EEEC31

So you measured 2 lights with the tube.
Then you measured both with ceiling-bounce (cb) and set the factor in cb to a value, so that cb shows the same amount of lumens as the tube?

This way you could get reliable results with cb afterwards for all other lights…
(not taking into account, that different reflector characteristics will for sure also have a large effect on the results)
