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

Convoy C8 is a good starting light.

This is the BLF GT thread. If you go to http://budgetlightforum.com/forum/flashlights/general and then click on ‘New topic’, you can ask there and you’ll be far more likely to receive replies.

I wouldn’t trust any brand that claims their 18650 batteries have 6000mAh capacity (I think 3500mAh is still the maximum that’s possible), or who sell ‘Cree T6’ flashlights that allegedly put out 10,000 or 20,000 lumens. I doubt that the Cree XM-L T6 can be pushed much harder than about 1,000 lumens, and most of those cheap lights don’t even have genuine Cree LEDs, but inferior quality ones (‘LatticeBright’).

Another shop, selling GT

You are right.It seems that they put a very poor packaging,so as the Customs officials believe that the included item is of low value. :slight_smile:

I have some properties I manage with large yards that have little or no light.[/quote]

How big are the yards ?
What do your family members want to use the lights for ?
The 2 above questions will determine what lights you need.
It could be that a flooder like the BLF designed Q8 would be better for lighting up the yards & a simple Convoy S2+ might be ideal for the family use, it all depends what the use is ?

@Brenton , Please seek purchase advice in a new thread, this is the GT Thread !!!

WOW!!! That is some price, if my currency converter I used is correct ZAR 8,999 would translate roughly into €625 / $767 :open_mouth: :open_mouth: :open_mouth:

Arrived here as well! Horrible packaging with gaping holes, but no damage to the head or body.

And at maximum ramp level measured 4100K at a perfect tint of duv –0.0009.

I vote that for any other blf group buy that you are purchasing a light in, we make dang sure you get one of the very first lights. Your analytical capabilities are fantastic (just wish I could understand it all)

Ok, I didn’t bother reading the last many pages as I saw it was mostly drama, remember, things get heated and the thread will be closed.

If there is something important that I need to see, please point it out to me.

Great, test, confirms my eyeball that the tint is really good for a 70CRI LED.

Have you tested it in turbo? I am guessing it will get a little cooler in full turbo.

Didn’t test turbo.

I know the beam doesn’t converge when measuring at close distance, but for what it’s worth, I got 860kcd at 6.1 meters on the max ramp (6.1^2*23106 lx on the CRI measurement above). So even this close, it’d probably be around 1Mcd on turbo.

Yep, those numbers sounds about right from my own testing as well. It generally takes about 20m to get the peak throw numbers and turbo will make a difference in meter readings.

I have had both of my GT’s in momentary mode the last few weeks, it is fun to just blast them.

:+1:

Mine is doing 850kcd in turbo with 4 cells NCR18650B panasonics (not high amps) but thoigt it only draws 2A per battery? Or am I wrong?

So max throw is only possible with 8 cells?

At what distance you have put the luxmeter?

10 meters

Part of it is the distance but yes, with low drain cells like that and the higher then expected Vf of the LED (we have planned on 1V lower when designing the driver) it will fall out of regulation much faster then planned.

For best results try some high drain cells and put in 8 cells if you can and see if the readings improve.

With only 4 laptop cells (about the same quality as the ones you are using), I noticed I could not hit full 2.5A to the LED in my light.

With GA cells it worked fine though and 30Q worked even better for regulated runtimes.

That’s the only way I’ll use it. Same thing with the D1S. That’s what throwers were made for.

Just got back inside from the first outside test and it’s a ridiculous beast. Good job GT team!
