I like the battery tube more than on the old Q8, too.

But - What does the “T” on the switch stand for?
I thought it stands for the manufacturer of the old Q8 - THorfire - will we get a different switch-cover on the Sofirn Q8?
Or are they also manufactured by Thorfire??

T stands for nothing but for better finger touching. It could be many dots or other designs but we already have this. We might use new design of the cap if there is good new idea.

Do you have any ideas?

I assumed “T” was for Thorfire. If you did order new ones, maybe use a “S” for Sofirn. IDK, it’s not a big deal. Maybe even a blank cover.

I’d say don’t waste time or money on new caps. Use up what you’ve got. It doesn’t change the functionality of the light.

I agree. However after depletion of caps stock I would consider doing something stylish.

I have 3 lights with NarsilM. At 23°C room temp I got, 19°, 21° and 22°. You certainly have a large deviation. Are the lights internals at room temp? Any time you use the light it gets warm internally and you have to wait maybe an hour or more for it to fully cool down even though the exterior may already be cool.

It’s very easy to set your own temp stepdown if you want to switch from timed. I did a video on just this procedure.

Like i said, the light was not being used. So i’m pretty sure the internal temp is equal to the room temperature. I know how to switch to thermal stepdown, but i don’t want to use it. Just want to check the temperature that’s all, weird hobby right?

It sounds like you have been lucky. I have seen identical lights report temperatures 20 C apart. The firmware’s default value is intentionally toward the safe end of that scale, since it’s typically better for some lights to step down early than for some lights to step down too late.

Anyway, with a range of perhaps 25 C variation from one light to another, it’s useful to have a calibration function. Aside from improving safety and consistency, it also makes the temperature check function sort of useful as a thermometer.

So guys and gals, Sofirn has told me that they’ll soon start shipping the extended battery tubes for the Q8, along with carriers which will hopefully have, as they said before, upgraded springs.

Got this link from Barry yesterday, lego-fun with battery tubes :party:

[Sillen]

yup, 70cm torch for walking the dog

[contactcr]

any word on battery tubes?

[Barry0892]

Battery tubes is ready to manufacture for BLF Q8, but a group buy interest list will help.

[BlueSwordM]

Oh OK then.

Perfect. I’ll perhaps be in line to buy one.

[DavidEF]

@BlueSwordM

Oh OK then.

So…

@Barry0892

…a group buy interest list will help.

[BlueSwordM]

Ok then. Since I’m free this evening, perhaps I should start a group buy thread list for this extended tube/light.

Or I’ll just repurpose this thread for both info about the Q8 V1.5 and the extended battery tube GB.

I would def be in for the one of the Extended battery tubes and carriers!

I can see no need or reason for this so put me down for one :smiling_imp:

[BlueSwordM]

UPDATE 2

The BLF Q8 and Sofirn Q8 extended 8x18650 tubes have started to be manufactured.

I will be starting a group buy interest list to gauge interest and how many tubes you want so Sofirn can produce the right amount of carriers and tubes necessary.

BlueSwordM has been added to the list for +1

Fate0n3 has been added to the list for +1

Sillen has been added to the list +1

[contactcr]

Add me but wouldnt you need at least 2 tubes to make 8 batteries? It replaces the existing one?

[BlueSwordM]

They are probably going to send an extended tube with threads that can be turned on the normal tube+2 carriers.

TLDR: 1 tube that threads on the existing one+ 2 carriers hopefully.

contactr has been added to the list +1

Edit: Not so sure about that anymore.

This is what I was going to ask if these will be sold as an almost “Kit” such as 2ea tubes and 2ea battery carriers to make this work or if we need to purchase 2ea of each. If that make sense lol

Can the BLF Q8 original tube be used with a carrier it looks like it is machined tube? Sheesh this is gonna make me buy the new Sofrin edition also now so I can have a light each way… lol

[BlueSwordM]

Yes. That’s why this took some time for Sofirn to manufacture them.

They’ve had to make special battery carries that work like in the BLF GT, and make an additionnal tube that threads on the original one.

That would mean you can just remove the tailcap, screw on the new tube, put in the carriers with the cells, and screw down the tailcap onto the new tube, and voila! 8x18650 Q8.

Edit: Not so sure on that aspect anymore. I’m waiting for Sofirn to respond on that.

Thank you big time kind sir for the response!!! That is awesome and great news. One last question for us looking to purchase is to ask if we will be required to run Button top cells? not that is a deal breaker just so that all of us interested know and make sure we have button top cells ready to go for this.
