Hello everyone
Is there is an upgraded version of BLF Q8 ?
THE question in other way, Is there is a can light like the blf Q8 that have 4 leds and 4 battery cells but lets say with 4 XHP50.2 or SST40 LEDS
I Have the BLF Q8 and so happy with it ,and i have been busy for a long time and I don’t know if there is a new lights came to world in the same size and shape
MT09R?
Yeah but you have to make it your self……
IF you really want 15-16,000 or even 17,000 lumen’s 
I also have a sofirn q8 and like it a lot but I know almost nothing about modifying the lights like that. Can someone refer me to some good resources on how to learn to modify them?
Not to be Mr Glass-Half-Empty, but those aren’t the best lights to try to modify.
Usually means reflowing the LEDs, possibly drilling into the reflector to widen the holes, shimming or shaving something to get a decent beam and not ringy and/or doughnut-holey, and then there’s modding the driver to push more current through the LEDs (sense-resistor or whatever the Q8 uses).
Get an S2+ or something, and start slowly. Better to break a 15buk light when learning than a 50buk light.
Will be on Black Friday sale $144. Usual price $145,8.

There’s numerous lights with more lumens, but generally, they will be more flood, and less throw.
The BLF Q8 has been measured at roughly 5000 lumens and 50,000 candela (10 Cd/Lm = mix of flood and throw, which is a good compromise for a range of uses, and similar to the Convoy S2+).
If there is a suitable driver, it might be possible to get around 8000 lumens from a Q8 with a similar beam by modifying it to use the XHP35.
The Acebeam X80-GT is one of the most extreme lights of a similar size, capable of a peak output of 32,000 lumens even though it is slightly smaller, but actually capable of less distance than the Q8 with 34,000 candela of throw (1 Cd/Lm = a really broad floodlight). It’s a marvel in its own way, but perhaps not as general purpose as the Q8.
There’s several lights in the middle. The Thrunite TN36 and Olight X7R both get around 11,000 lumens and over 30,000 Cd (close to 3 Cd/lm).
If you want a light with a similar beam shape but significantly more output while maintaining a similar beam shape, it will generally have to get bigger. The Acebeam X45 is a good example, with 18,000 lumens and 109,000 CD (6 Cd/Lm).
Tn30 mini was around $79 not too long ago
Yes I agree
I kinda understand Reflowing the led, at least I think I can learn to handle it but how do you mod the driver? And how you choose which one and where do you find the driver you need for a different emitter? Let’s say I wanted to mod the convoy m3 with something that doesn’t turn off the high mode when the battery reaches 3.7 v. And so that I can ramp it? Up and down? Would I need to change the driver? Thanks!
Haikelight MT40, I just received mine, got it for ~$41 + shipping. 4x SST-40, 5000k, 8000 lumens, 850m throw, simple and useful UI.
Care to share? 8K Lumens/850m throw sounds fetching.
Sure, BangGood usually has the best price with a coupon:

You could ask these guys if they have a current code if the listed ones no longer work:
Modding the driver the way you describe (disabling LVP, for one) means reflashing the µC at the very least. So, it’s gotta be a µC that someone supports, and getting all the stuff to do it. Meh.
I got all the stuff to do it, but never did.
how about the Fireflies ROT66?
Nice and more compact as the Q8, but noticably more floody.
He will be disappointed if he gets the rot66 as an upgrade to q8. It heats up fast and will dial down to a low temp. What he really needs is an mt40 by haikelite. No ramping, but basically it’s his light on steroids. 1.5 stronger and throws far
There than sofirn q8 and costs the same is not less. Will not disappoint . I own both , and I have to say thought mine starting acting erratic after some use. Hope it’s a one off.
Yes it’s a little bigger ( longer and bigger head) and bit heavier but the part you are holding is the same size and the pluses outweigh the minuses
The Sofirn Q8 in XPL HI has been out for a while. Wonder if there would be enough appetite for them to do an update with a new emitter.
I’m personally fine with the OG BLF Q8 though, just a thought.
@gamezawy, if you want a stronger BLF Q8, I would recommend you bypassing the springs and getting an AR lens from Kaidomain:

Wow thats really strong light, what driver did you use or did you moded the stock driver ?
And what MCPCB Did you use ?
