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 ācarryableā. 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 āoversized toyā with limited practical use.
My intentions is not really to try and squeeze out more juice, but to make sure they didnāt use that crap white rubbery thermal paste, and that the LED has got enough heatsinking behind it so that it can handle the heat. I modified my BTU Shocker into a SuperShocker over the weekend, and I was surprised at the crap thermal paste, very thin LED shelf and big unutilized gap between the LED shelf and the driver. Filling that with copper or even aluminium will help the LEDs a lot, and I was wondering how the BLF GT70 would compare.
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. Thatās about all I can tell you. Iām not sure about specific run times.
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 misunderstandingā¦ I measured both olight st96 and mt18vn with the TA tubeā¦ TA tube show 10500 and 10720 lumenā¦ then I use light meter app to get the all the lux reading. Thatās the only way I can get good reading on the blf gt lightsā¦
Yes sirā¦ it is not the right way to measure lumenā¦ i know two lights are measured by TA tube and use them as a referenceā¦ the lumen number are pretty good as you can see by my testingā¦ those are @5 seconds lumenā¦
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 Thatās 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 canāt 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 didnāt 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 Iāve 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 haā¦ wow
I guess the GB might be sort of over with if their advertising a code of their own as well, I canāt help wondering why bother with these codes, just sell the light for $220 and skip the codes, nothing is secret anymore, thereās codes everywhere.
But, out of all the codes Iāve seen TAās code is the very best so Giggle thatā¦!
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 lightsā¦
(not taking into account, that different reflector characteristics will for sure also have a large effect on the results)
