Official Group Buy Now Live! Lumintop BLF GT4 4x XHP70.2 30,000 lumen 1300m 7lb passive cooling beast!

Update, very sad news, it seems my contact somehow got things very very mixed up.

The GT4 will ONLY support 18650 and NOT 21700. Seems they made a prototype of the 21700 at some point and that is what he thought was going into production. They are sticking with the 18650 version it seems though. (they are having a real hard time getting some components in, as we can see from the GT90 kits taking so long)

If anyone that placed an order wants to cancel since it does not support 21700 that can be done. Very sorry for this mix up, I was as excited as the rest of you lol.

On the bright side, unprotected button top 18650’s are a lot easier to find than unprotected button top 21700’s.

Tempting to say the least. Have an X70 on back order from Illumn for a month tomorrow, not sure if should cancel and order this; would love to see a review on this beast first though.

yeah, and a lot cheaper.

Neal actually just found a source for 40t button tops when we found out about the mistake lol.

Speechless… Texas Ace I have to hand it to you, I would be pretty upset between the fact they launched this without letting you know, then told you the light was shipped but got returned to sender.
And now this. Another cluster duck of a deal.

lol, you learn to roll with it after awhile.

Looking forward to your measurements!

Starting work on my video today :slight_smile: Thank you TA for your inspiration and dedication on the project.

Do you know who designed that battery carrier?

Can’t wait to see it!

It was a group effort design. I gave them the base idea and they figured out how to make it work / turned it into a CAD design that could be used. My hand drawn sketches were not up to being manufactured to say the least lol.

Although my idea (and what they were supposed to do for the final light) included a PCB between the stacked cells to both help hold them in place and prevent cells from being inserted backwards.

I hope that made it into the final light?

Not necessarily a terrible thing for those of us that have tons of 18650’s laying around.

Only thing I wish could have been designed differently is the reflector. In the video on youtube of the prototype, posted by the gentleman in ausy that you sold it to, you can really see the points of the 4 individual cones around each led. Wish it was just a smooth circle of light instead.

Wow. OP reflectors and still 1300M+ throw? That thing is incredible. It would be nice to see how it holds the output without active cooling.

You have no idea :smiling_imp:

Its there.

It only comes in a SMO reflector as far as I know.

Good, I had some issues convincing them it was necessary at first.

Just waiting on VOB’s review to pull the trigger :smiley:

The picture on the Lumintop website shows LOP reflectors. Is this not the final version? GT4

Very interesting, that is a change from the prototype, I was never informed of that change. Looks like you might be right about the OP reflector.
