The BLF GT70 "Giggle Monster" is here! 7,500lumens, 1,500m throw! Group buy Closed!

Since I was quoted…. This seems to insinuate that expectations were based on some sense of entitlement. You might add to your list:

  • 5. From post #2: “The sales of the lights will go directly through Lumintops store this time once the sale is active, no more having to mess with paypal transactions in various accounts. This should VASTLY improve the ordering process and mean everyone should get things like tracking numbers much more efficiently.”

I didn’t mean to “insinuate” anything by quoting you. I just found it interesting that when you asked Leo for your Conversion Kit Tracking Number he was able to provide it.
That would seem to possibly indicate Leo does have access to the Conversion Kit Tracking Numbers & has just not had or taken time to send them out.

But, as far as I am concerned; in the big scheme of things…. so what? We will get them soon enough…. either the package or the tracking number.

At this point I think everyone has aired there feelings and everyone has a right to their own opinions. I fully admit that delays were well outside of what I planned on and am sorry for that.

All orders were shipped up to Oct 18th, if you need a tracking number please contact Leo@lumintop.com and he will get you squared away.

Hopefully they start getting delivered soon.

Agreed.

So I took my OG GT out for a walk last night, boy I love lighting up stop signs from a mile away at quarter brightness! And deer in the field a half mile away lol. Can’t wait to get a dedomed xhp70.2 in there and see what it does.

I just received my conversion kit today in Australia.

I can’t wait to see it perform!

Now for a little time soldering.

Now where are those videos again?

I have the head and other bits loose.

This video shows the process, although you do not have the reflow the LED with the kit.

I have now installed the conversion kit and everything is running great.

The switch wires could have been a bit longer as they have to be cut and soldered back in again.

To get the ring holding MCPCB in I used circlip pliers with very thin ends on them.

This thing sure puts out some light with a much bigger hotspot.

Good work team!

Why didn’t the new switch fit through the switch hole? Was it thicker?

Received my conversion kit today.
Thanks

My conversion kit arrived Monday.Thanks team.

Is there any empirical data on dedoming CW vs NW 70.2’s? I know dedoming tends to shift the tint warmer, and so CW is recommended. But what are the numbers?

I don’t think there are any numbers at this point comparing them. And since the conversion kits are just now showing up it might be a little bit before we have much data.

I don’t have CW/NW comparison just dome/dedome in Astrolux MF02. with dome I had 9000 lumens and 7500 after dedoming.

Texas Ace Alright I guess I’ll wait before I dedome. Or I’ll dedome and try to do some reproducible beamshots before and after.

Zozz so lower lumens, but did you get more throw? Odd how that works, I get that it throws farther because it’s focused better, but why do the lumens go down?

I’m concerned about throw first off, then color temp. Ideally I’d like it warm ish, but I don’t know how much warmer it’ll go, and I probably should’ve started when CW I think. Nothing to it but to do it though I guess, so I’ll dedome the NW. But I also got a spare NW that was even warmer, I’m an idiot, I should’ve went cooler there too haha. I can always get a CW emitter, but these aren’t as cheap as xp format emitters.

With dome I had 226125 cd
Without dome I got 355500 cd

The lumen loss is because no reused light because of dome missing. With dome some of the light reflected back from the dome surface to the phosphor and then it going out again so it reused. I can’t explain it any better but I read it somewhere more better explained. That is why a Wavien is used in Aspheric high output mods. It reflects back that light which unused and othervise not hit the lens.

I do like the Lumintop BLF GT very much. I have this idea of line of succession of best flashlights. It goes, 6D Maglite, Surefire M6-CB, Olight SR90, Lumintop BLF-GT70.

Totally only my own view. :smiley:

Yes, you will loose some lumens but gain throw.

As a general rule we have been seeing around a ~40% increase in throw and a ~20% loss in lumens with the XHP70.2’s.

Based on my own testing I would say it generally gets around ~400-500k warmer after the dedome but the green tint shift on most LED’s is what stops me. We will have to see what people think of these particular led’s when it comes to that. So far I think someone said that the CW did not have much / any green after dedoming.

Today is the last day for orders!

Ordered on 10/19, received today 11/1 - Chicago, IL.
Cells are charging; trying to suppress all the giggles.
Cheers all.

Editing to mention, Lumintop threw in a shoulder strap for me for free. Very delighted with this group buy. Thanks.

Thanks for the info Texas and Zozz!

That wavien looks nuts! I wonder what that would do for a GT70!?

Green doesn’t bother me so much I don’t think, this isn’t an often used light, it’s more of a wow factor light. But by that standard I’d want it as cool as possible for the light saber effect. We’ll see what we get!
