[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

Alright, alright, those renderings convinced me. :sunglasses: Sign me up Scotty!

No one upset here. It is a legitimate opinion.

I guess it is easier to convert down to 1S then up to 2S. All they would need is 4 dummy cells to convert. They would not be able to run 8 cells with an XP-L.

The conversion would actually not be as bad as I was thinking (used to the SRK that is a pain to convert to 2s or 4s).

Yay, we hooked the big man himself, we must be doing something right! lol.

Never mistake my silence for indifference! :smiley: I’ve been lurking on this thread since day 1.

Is there a way to design in some kind of safety mechanism to reduce the risk?

:smiley: :+1:

Risk of what exactly? risk of someone being stupid?

Sadly Stupidity is an incurable disease that plages millions around the planet ever since natural selection’s cycle was interrupted in the last hundred years or so. It is destined to get worse.

Anyone here ever seen that documentary “idiocracy?

In all seriousness, it should not be an issue but the PCB’s we will have in the carriers would have the ability to use fuses if it was deemed necessary.

Me too, sign me up !

I am interested in one depending on the final specs and price.
Really appreciate the effort to beat a TN42 for ~100$. But i have a few concerns.
First the modability (thermal design). The actual design should be capable of running a 20W LED on 100% for quite some time without getting to hot.
But without improving the thermal design (E.g. additional smaller and longer fins to increase the surface area at the base) switching to a more powerfull LED (in the future) will be a problem!
And i think because we are here at BLF, modding the light is not something that only 1 or 2 people will do! Imagine a year from now there might be a LED on the market that puts out 2500-3000 lumen with a die size of an XP-L. I know what i would want to do then. Or maybe there is a high power LED like the XHP70 with 6000lumen but it is one die Like a SBT-70 or MTG-2.
I am definitly interested in this light! But if future modding is not possible or only possible if you put a disproportionate amount of money and work into it to make it work i might better keep searching for a different light.
And it is the same with the cell setup. If modding the setup is not possible or only with a excessive amount of work (near a rebuild) i keep searching for something else.
Still hope that the final product is capable of handling at least 50W+ (it does not have to be like a TM36 even if this would definitely solve any heat problem) and is mod friendly.

The head of this light would weigh over 1.5lb, needless to say it can absorb and dissipate a LOT of heat.

the issue with adding more fins is it would add even more weight.

You need a CPU heatsink and an active cooling fan if you plan to run an XHP70 at 6000lm, unless you’re comfortable with your LED going over 85 or 100C and having reduced output.

Yes, a user-friendly design is crucial. I have another question. Will there be enough room in the driver cavity for an optional driver change? I dont need much, just hope it will not be designed like the Palight Boss1 with 9mm of vertical space in the driver cavity.

It will have some extra space, I think I asked for 15mm for the first render, it will be adjusted before production I am sure though.

Just give it an extra 100 or 200mm in there so we can store a sandwich and drink too!

Could do that and basically create a modern maglight so cops everywhere can carry a big stick and not get sued lol.

Haha I still have a 4D maglite sitting around somewhere from back when I thought those were “high power” flashlights….
Because 4D must be brighter than 3D cells, right? xD

Sign me up also depending on final price

why we keep using 18650 at this size?, 4s 26550 would be better in my opinion

It was mentioned earlier, people want to be able to hold the thing.
26650s would require a handle to hold it, and at that point they may as well do the box design they originally had in the vote.
More people voted for this style of light, so that’s what they’re going with.
Also, more people own 18650s.
