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

It’s official the GT4 is finally ready for production!

Here is a great review by VOB to let you see what this is all about!

This is a beast of a light, as far as I know this is the heaviest and best passive cooling production light to exist on the consumer market. Loaded it should weigh ~8lb+!

This light has been a project I have wanted to get off the ground since the first GT back over 3 years ago. In fact in my initial pitch for the GT the second thing I pitched right behind it in the email was a quad version of the GT, aka the GT4.

It runs 4x XHP70.2 led’s powered by 8× 18650 cells for a massive ~400w+ of power!

The real standout feature of this light though is the passive cooling design. As far as I know this is going to be the best passively cooled flashlight to ever be produced for the public. In prototype testing I was able to run it on turbo until low voltage protection kicked in without reaching damaging temperatures for the light (now, your hand would not be happy with 90-100c temps but that is another subject lol).

Output was tested by VOB at 32,000 lumens!

The NW tint is 4000k, CW tint is unconfirmed but either 5700k or 6500k.

This is quite literally the GT70 ×4

I am really looking forward to this light being available, several years to late but better late then never I suppose.

This group buy will work much the same way the GT90 worked. The lights will be sold with a coupon code from Neals store and shipped as they are produced.

Be aware there will most likely be delays in shipping, particularly if these sell quickly. Covid is still causing delays and they are having trouble keeping up with demands as it is.

Here is the link and code to buy the GT4 now if you don’t want to wait for reviews:

Coupon code: TAGT4

$110 OFF

Neals Gadgets GT4

So total price works out to $289.95

There is also a combo kit with 8x VTC6 cells and a Miboxer C4-12A charger available from this link using the same coupon code:

https://www.nealsgadgets.com/products/lumintop-blf-gt4-kit-flashlight?af...

The code also takes $110 off the kit.

I will update as I get more information.

Reserving this post for future use, figure I will repost the link since it kind of gets lost above:

Looking forward to your and VOB’s review. The idea of the best passive cooling is appealing! I wonder what the confirmed throw numbers will be.

Are the NW XHP70.2’s 5000k and 70 cri?

Is it possible Samsung 50E 21700’s with a slightly raised flattop might work without a solder blob or button top added?

I actually did not get confirmation on the NW that will be used in production come to think of it but 5000k 70cri was the plan in prototype stages. I assume it will not be changed unless they had supply issues.

I highly doubt that a flattop of any kind will work without removing the protection PCB on the carrier. Better off solder blobbing over removing that.

There’s no reason why it can’t be close to 25,000 lumens. Also, with such large reflector wells, the throw should be 1370 meters. Thanks and congratulations to everybody who made this standout light possible!

Think of how hostile the average surface of the earth is, and realize half of the surface of the earth is more hostile than that.

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.

Do you know who designed that battery carrier?

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.

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

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

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.
