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

That’s correct, ideally you only use those cells for the GT.

1210 you are good to go

MiBoxer is coming out with an 8 cell charger soon, according to Leo

I am in.

can wait to take this camping

thanks to everyone involved in the project a truly beautiful light

Another 8 cell charger Test/Review of Charger GyrFalcon All-88 (Enova)

just get what i got, a sky rc charger, and charge em at 3 amps x4
can do 8 cells in hour and a half or so :+1:
lifes too short for slow arse chargers i say :stuck_out_tongue:

I’m in, please add me to the list for 2 lights if possible, also how will I know if I’ve been added or not?

Yes!!! I am 1065 on the list!!! I wonder if the light will be shipped out by April 2018 because that is when my next CPF meet will be…. lols….

List on first page. Might take a few days for Miller to update. Patience is key.

What does the sky rc charger cost (what model are you talking about) and how can it charge 8 cells if it’s 3A x 4?

The Gyrfalcon All-88 does 1A x 8 and runs about $58.

The Liitokala lii-500 does 1A x 4 and costs $25. So you can get 2 for $50.

The Miboxer C4-12 can do 3A x 4 and was on sale for $32. You can get 2 for $65 and charge at 1A, 1.5A, 2A, 2.5A or 3A each, whichever is safest for your particular cells.

Miboxer is planning on a C8 version which might be cheaper than $65 (price not known yet), but it is still a ways out.

So there’s lots of options, you just need to decide if 1 big charger or 2 smaller chargers best fit your needs.

Your right, the cells should be matched and married. Just keep in mind that Kingjohn said that if they were no longer needed in the GT they could be used elsewhere.

I read it as if he had 8 matched and married cells, then decided it was too heavy and he didn’t need the extra run time so he kept 4 cells in the GT and then split up the other 4 to use in different lights. That is perfectly fine.

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?
