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

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.

Sending the light to Texas ace for diagnostics. I just don’t have the time to tinker. To many other hobbies going on. Appreciate the recommendations and help!

My bad, saw 3V and misinterpreted. Kinda skimmed over it. So I guess it really does eat batteries.

It shouldn’t draw any more power than the GT70 does. These are rough numbers as the voltage and amount of voltage sag will vary based on the batteries used.
4v x 30A = 120 Watts
15v x 8A = 120 Watts

Shame I got the 1st one, although I am still happy with it, and the price was spectacular. This thing is really powerful as far as throw, I’m still amazed, but 7,500 lumens vs my 1,800. No doubt, I would be giggling.

You can buy a kit with new led, centering ring and driver from Neal’s gadgets if you want to convert it. I think its $50.

Yeah, I saw that. May possibly do that but not sure about trying to get that head apart. Would hate to scratch my baby. Maybe with a strap wrench.

You definitely need two rubber strap wrenches. They are cheap, though. $5 to $10 for a pair.

I needed only one strap wrench and wrap the bottom part in a towel in a vice. Would of been harder without a vice

Get two wrenches as Jason suggests. It’s very much worth it
