Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

With the cost and risk of developing new optics, that was a moonshot wish. It would’ve been nice to have a light more comparable in size and output to the M43 with the UI of the Q8 though. Actually, I’d be okay with a mule and shortening the head since it wouldn’t have optics, but the market for mules seems to be tiny, which makes that a nonstarter. I’d still like them to ditch the flats on the battery tube. It’d speed production on a feature that does little to nothing.

I’d love to see them come up with accessories. While the AOD-L diffuser works, a silicone diffuser would be better in a few ways. The tailcap I want could be an accessory so that all Q8 owners wouldn’t have a longer light forced on them. I’ll have to see if my injection molding machine can handle a shot big enough for a diffuser so I can get at least one of those things.

For the UI they can use NarsilM v1.3 instead of 1.0, they can adjust some times or they go with AndĂșril.

Today I recieved my new Q8 lighted switch to replace the stock switch that was flickering and later just stopped working. Can someone help with the wiring of the switch? The stock wires are all red and the new one have different colors can you tell me which wire goes where?

Thanks in advance for your help

Here is a pic of the driver, the wires go on the right on the pads named G, L, S

I see, Thanks I’ll give it a try and report back


It worked! Thank you so much! :slight_smile: :beer:

This is the correct wiring for the replacement BLF Q8 Switch


I put a small dot of crazy glue to prevent the switch from rotating when I screw back the silicone boot

Bought one too. Maybe I’ll come back and ask how to dismantle the lamp’s head if I have some issues.

It’s easy. You just need to have some good strength.

If not, just use some carpet to help you open it.

original Q8 MCPCB is available on Aliexpres :smiley: :smiley: :person_facepalming: :person_facepalming:

Actually, I have seen that BLF Q8 MCPCB in the Sofirn AliExpress Store from several weeks ago (I often browse the Sofirn AliExpress store
), just didn’t know if it’s the original one or not. Since Tracy from Sofirn assures us that it is the original one, this would be good for those who need BLF Q8 replacement parts.

There are also a few other BLF Q8 replacement parts (BLF Q8 reflector, and switch assembly) from the Sofirn AliExpress store, in case anyone needs them:

@Tracy, I was the one who ordered 2xMCPCBs a while ago a few days ago.

And yes, it is the original one. And having messaged Sofirn, they are going to offer some other things soon, including the battery tube, and the tailcap. And a special surprise I will not tell yet.

I just got the Q8 and loving it so far :slight_smile:

Thanks to everyone that worked on this project!!!

Question: I am trying to find out if it’s worth the hassle to get a handlebar tripod mount to use the Q8 as a bike light. What do you guys think?

My concern is the weight of the Q8, although very compact for how bright it is, it does weight a bit when loaded up with all four 18650 batteries.

Just want to get some feedback on this especially from anyone who has looked into doing the same, thanks!

I wouldn’t want to trust only a tripod mount on a bouncy, pot holed bike ride with such a heavy light. I would feel more confident with some kind of large strap(s) or circular clamp holding the body.

I wouldn’t do it. Maybe we can talk Sofirn into making a remote battery tube adapter.

From the mtbr thread: BLF Q8 on the Bars? 5,000 Lumen Monster bar light! | Mountain Bike Reviews Forum That a nice looking plate/adaptor/mount thingy :slight_smile:

That’s a good idea, a remote battery pack and while we’re at it, how about a short replacement for the battery tube with connectors for the cable going to the remote battery case. One can dream :slight_smile:

That’s what I meant. It’d be two caps with contact boards and a cable to connect them. If it was used with the upcoming extendable battery tube, battery life could be made virtually limitless. I’ve seen pictures of a solution like this, but no details. It could work with 3d printed parts too, which would keep weight down further.

I used a ‘50mm quick-release truss clamp’ to make a tripod mount for my Noctigon Meteor M43, which lacks a threaded hole. The Meteor and Q8 both fit nicely in the 50mm truss clamp. I stretched some old tubes onto my clamps to increase friction and prevent scratches.

For mounting to a bike or ATV, connect another smaller clamp to grip the handlebars. This makes the light’s angle easily adjustable.

My 35mm truss clamp above closes down to almost an inch. There are also 20mm or 3/4 inch clamps on eBay.

Be sure to use a quick-release truss for the light’s end, so you can easily detach the Q8 when you’re not riding. It seems the smaller diameter clamps aren’t widely available with quick-releases.

Sounds like a good child project to the Q8. Wish I had a workshop that I can take on these project.

That looks really nice. Especially how the inner tube fits on the clamp, totally look factory.

Question, do you have any issues with stability, shaking or flexing?

Thanks for your help. :+1:

uhm
 I was in the first batch list for the Q8, but then I gave my reservation up to someone else because I was in tight circumstances
 but now of course I regret :s I payed 40 USD for the D4, which is worth it, but this massive light for the same price was just a gift
 wondering what is the lowest price it has been sold after that. I remember deals around 50-55 usd
 has it ever dropped to 40 again?

Not at 40$, but 46,50$:
