[PART 2] Official BLF GT Group Buy thread. Closed, but Public sales open!

Once you get your PM it will give you all the instructions. It will basically give you the website and the password to the order page. Then you can add the items you want into your cart, such as the GT and maybe the carry bag or the short battery tube or batteries, etc… Then the payment is done through PayPal.

Since you are in the US it will automatically be shipped through DHL with no extra shipping fees. So once it leaves lumintop you would get it within 3 to 5 days most likely. (This is what it was in previous US orders)

I am guessing you did not watch the video in post #1? If you go to 1:35 you can see the ordering and checkout process.

Today, two BLF GTs arrived:

They’re a bit ridiculous though, at least inside of a city where there simply isn’t enough room for a mile-long beam. So here’s another shot of the twins next to some more practical lights:

Thanks for clairifying it

Would Samsung 30Qs be a good battery to use with this light?

I knew they were big, but holy cow, thats absurd LOL.
Hoping to go up on Skyline Pkwy by Enger tower and light up the grain elevators by the harbor when it shows up :smiley:

30Q’s will be more than enough, but 35E seem to be the recommended cell for longer run time. This light doesn’t need the high amp supply as the light is only drawing 2.5A.

Sweet! I’ve been wondering when you would finally get your GT.

My fingers are crossed that Andúril and the GT play nicely without giving you much trouble.

I need lightning mode to harass my friend who lives a block away. :partying_face:

Wait for a night when we have a 2000-3000 foot ceiling, and shine it due east. I should be able to see it from Ashland. Better yet, when mine shows up, we’ll have to try and converge them over Iron River. They’ll think the world is coming to an end. :open_mouth:

So is the shipping version of this light warm or cool white and what is the candela roughly because I knew it changed through the build process as far as I know

Group buy versions are shipping with a 4,000k XHP35.

They are generally tested between 1Mcd and 1.2Mcd. I just took a reading last night and got 1.1Mcd

Ok, here are the results of my testing with the Dr Meter LX1330B lux meter and the XHP70.2 GT.

These readings are at 10m, outside.

First the stock GT for a reference point.

- 1.1 Mcd for a total of 2100m of throw

Next up is the XHP70.2 80cri GT with dome on

- 560 Kcd for a total of 1500m of throw with over 9,000 lumens!

Lastly the XHP70.2 80cri GT with sliced dome

- 750 Kcd for a total of 1725m of throw with over 9,000 lumens!

So needless to say I am pretty happy with the results. A P2 bin XHP70.2 could most likely get a bit more then this but I didn’t have any on hand when I put these together.

Here are some very crude beam shots that kind of show the difference.

Dome on > Dome sliced > Stock GT

Stock GT:

XHP70.2 sliced Dome GT

XHP70.2 dome on GT

I am officially listing both of these lights for sale and I can swap the LED to something else if someone wanted.

I will post a thread for them later when I have some time. PM me if interested. They will not be cheap sadly, this is one of the only ways I am making money off this project and I need the money.

I could only get 4 of these prototype mcpcb’s so I can’t make anymore of these unless they put it into production down the line. Which they are still not giving me a straight answer, hopefully these results will bring them around.

That sliced dome xp70.2 output and throw is awesome! Is that simply an emitter/mcpcb swap running the stock driver?

I’m kinda digging the dome on version myself. I like the more floody, Q8 on steroids output.

It also has a custom TA driver to get the extra output over the stock buck driver and custom centering ring.

It gives you an extra ~2000-2500 lumens with the TA driver.

Yeah, I am having a real hard time deciding which one I like better myself, every time I think I have decided I try the other one and I realized I have not decided lol.

You did not understand what I said at all. Please read it again. If it still does make sense, please ignore it. I can not make it any clearer.

maybe just stop worrying about the financial condition of LM

I’m guessing it is too big a language barrier. Sorry.
