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

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:

Grtz

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!

My GT in two parts arrived yesterday, too. The performance is impressive and matches what has been seen on a bunch of beamshots. In total darkness with average visibility conditions I didn’t have enough distance to exceed the usable throw without moving further. Easily illuminated targets within 1 kilometer. Nice,team, manufacturer and other parties involved!

The minimalist packaging might be due to some shipping rate limits at 1 and 1.5 kg, as the boxes had Finnish Post measured weights of 1.47 and 0.99 kg. I don’t know why the original declaration says 0.5 kg for both but I guess some involved party on the way might not have a scale at their disposal. :slight_smile:

I was kind of scared to see the two balls of brown cardboard or toilet paper that had been submerged in water. Miraculously the window was not broken, and it appears others had the same result. Good job, I guess. The actual light arrived undamaged even if a bit dirty. A couple of scratches were to be expected from any mail shipment, to be honest.

If someone has one out of two missing, I got a theory. Finnish Posti decided to deliver the tube with batteries into my unattended mailbox while the headpiece was to be picked up from a post office. Obviously they are required to only hand out a registered package against signature and ID, but this worked out this time. In case it wouldn’t fit, the mailman would have to take it back and it could take a couple of days to show up again, especially when the box including the label could very well be ruined and unscannable. Don’t panic, but ask for the tracking data and if available, use it to search locally. You would not want it to be sent back in a week or two.

What was funny is that the other tracking number didn’t show any movement via any tracking service between leaving the origin country and being available for pickup from the post office. The other package tracked fine all the way. Both arrived at the same time in the end.

Picked up my GT this afternoon from the post office!
The boxes were very clean and undamaged, they only wrote my name on the side of the box with a marker so it was more easy to find between all the other packages.

Will try to post images later, did not even open it yet :sunglasses:
