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

I think this is it: https://www.youtube.com/watch?v=cVKoVZkkCtk

OMG TA what a monster is this, nice you got it going, awesome, congrats!

Yeah, the GT70 turned out pretty good. Have a look at the GT4 for an even more impressive version that is sadly not released yet.

How risky is dedoming? Would you recommend it? How likely is a sbt.90 conversion kit? Should I wait?

It has risks, particularly if you have not done it before. I tell people to be prepared to replace the LED before de-doming.

De-doming gives a good gain in throw but the tint suffers for sure. Personally I don’t do it to my personal lights.

Does it have the same effect on the neutral white tint led? Sbt.90?? Lol

Yes, the effects are basically the same on all of them. The CW is the least noticeable as a rule.

does lumintop have any plans sell this with the sst40 emitter ?

First you need to ask if there is any advantage to the SST-40 over the xph-35hi?

I think lumens is about the same, but SST-40 has a tiny bit smaller die. 1.99x2 to 2.35x2. I doubt the small increase in throw would be worth the effort to design a new 3v driver for it. Botton line, I dont think it would sell well. Maybe Lumintop can test the waters to see if people are interested.

ah okay… was thinking since the ft03 is such a great thrower with that emitter maybe blf gt would be also but if not much difference between i guess not hehe…

I highly doubt it, the SBT-90.2 is the next step for this series of lights.

totally understand… another question, does lumintop still make the xhp35 or xhp70 version or is it sold out?

Last I knew they were still being sold, don’t see any reason they would stop selling them unless they ran out of stock.

BLF GT70 Issue.
Light will only ramp up to maybe 20%. I get a double blink when its at its low output max.
Double click of the button for turbo mode yeileds the same result in output.
Cells all measure 4.17-4.18v Samsung 35E button tops
Factory reset also yeilds the same results.
Any ideas?

Could be a bad connection by cells / carriers. Or a bad driver. Or a bad LED depending on exactly how bright it is, this is the most likely issue based on what you said.

Texas_Ace maybe the one to ask to test it if he has the time

Battery check with the cells in is 4 blinks then 2 blinks. So 4.2?

To rule out the carriers and batteries, clean all the springs, and connection points on battery tube and driver

For it to drop in output suddenly while using sounds like the LED or driver.

You still might be able to get a replacement over at nealsgadgets. This would require you learning to solder but the hardest thing is opening the head. You’d need two rubber strap wrench and a maybe vice

So I’m guessing this thing eats batteries for breakfast ? Own the original GT XHP35 but have never ran it to exhaustion. How long would this new 1 run at say half power ?

Edit: Didn’t realize it was lower voltage, nevermind.

Where did you see it is lower voltage? Both the GT and GT70 run at 12v?

The new GT90 runs at 3V but that is because the LED is a 3V LED. It pulls almost 30A to make up for it.
