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

Thanks for the testing TA.

2490 lm — 2 A
2630 lm — 2.5 A

If I’m not mistaken, max ramping is 2 A and turbo 2.5 A, any plans on lowering these numbers?

More than 7 8.5 W for 140 lm doesn’t really seem worth it.

edit: wrong math it’s more like 8.5 W

That is exactly why we dropped the ramp max down to 2A. Going from ramp max to turbo is hardly even noticeable when you see it happen.

No need to go below 2A, that is a good output for the xhp35 before it really starts to drop in efficiency. Turbo is for people that want every last bit out of the light. I would not use it long term, while the LED handles it fine it sure doesn’t do it any favors and it figures that it will wear out faster. Better to just use the ramp max.

Wow, I just noticed that this GB has over 1200 people on the list! I was hoping to crack 1000 when I started on this project, glad to see I didn’t overestimate the desire for such a halo light.

In all seriousness, it’s awesome and we can’t wait to hold them in our hands! TYVM for everything you’ve all done on this project! :smiley:

I ‘Ctrl-F’-ed on the first page of this thread, and I didn’t find my name. Can I please be added for one? I had originally put my name down back in post #6451, and I wonder if I was accidentally missed.

Thanks to everyone involved in making this light happen - making something this great takes a lot of time and effort, and I appreciate it!

I agree 2A is the sweet spot.
Only downside, if you don’t want to use 2.5A, would be loosing the 2 clicks to max, no biggie.
Upside is when a xhp35.2 or other new led, that likes a bit more current comes out, one could just swap out the mcpcb and have the extra current with turbo, without having to mod the driver.

Am I on the GT list?

So what upgrades we are still waiting or are they starting production soon?

:wink: :wink: :wink:

The LED has been settle and I suppose this is as good a time as any to tell ya’ll that the host has officially gone into production!

Still a few minor details we are talking over but nothing that should cause any major delays.

No word on when to expect the finished light yet but at this rate in the next few weeks seems reasonable.

If you double click to turbo and then hold the button for just a second it will drop back to the ramp max.

Although for about $5 you can get the parts you need to re-flash the driver and you could then setup the driver with whatever max you wanted. If it was asked I bet Tom could even make a pre-made hex file with a lower turbo output.

Ah, that would be the 35E deal that was talked about.

Yes, that is about the best deal you will find for 35E cells for the GT.

You are absolutely right. If I need only one cell for another flashlight, I will always take a different one…
All should be used the same amount of time…
And before using them together again in one light, I will fully top them up all together in the same charger.

All should have the same level of wear especially in a 4S1P light!
And none must have been over discharged, otherwise the danger of a mismatch is high.

If they are no longer perfectly matched, you can still use them together in a 1S4P light (the BLF Q8 for example).
In a 4P configuration, if your have a cell that delivers less power, the others will take over.
Here you just have to ensure, that the others can deliver a higher current in such a case.
(Your have to know the specs of the cells)

But if all 4 cells are always used together in the same light, you most probably needn’t care for all those things…

Could you please put me on the list for the new BLF GT flashlight. Thank you. Berts.

:open_mouth: :open_mouth: :open_mouth: YEE HAWWW!!!

Why is no one freaking out about this? This is HUGE! Finally congratulations!! :sunglasses:

Got to stay calm and relaxed. The freaking out will hit when ordering instructions show up in our PMs :partying_face:

Then mass amounts of “ordered” and didn’t get PM posts, will be made. :person_facepalming:
