Sofirn Q8 group buy (gb closed, but try PM to Sofirn for discount)

Yes flats for me for the weight decrease and looks. That’s if there is a choice, otherwise I don’t care flats or no flats.

I like the proposed 36. What Leds ? I have been interested in longer run time lights lately like 26650 or multiple 18650s . I like the option to charge with USB if away from home .

The last 7 comments were about the SP36. Maybe it needs it’s own thread?

Well, since Sofirn asked djozz to run this group buy and Sofirn themselves posted pics of the SP36, guess it’s their call.

Still waiting on the Q8 to arrive, even to leave China, so until they start getting in our hands there’s not a lot to talk about in regards to the Q8 of this thread…

A thread in which to talk about a flashlight with not much info yet, that is in prototype stage and in which BLF is not involved sounds very BLF to me :party:

They’ve spoken about it on reddit before.

They wanted to go with NarsilM and a 3x18650 design. We suggested that they take an XHP70.2 80CRI or a Nichia 144AM R9050. Don’t know where it is now.

Is it a single emitter? Triple? Quad? Inquiring minds want to know!

Here is the thread:

I am interested in 1x 8Q, AliExpress

It's not a deal breaker for me either, but I was just trying to sneak away the prototype flat tube if Sofirn decides to use the round one in production

I like the flats, but I think they are best done when the threading is indexed so the flats line up with the button/other features on the light rather than random orientations. The indexed threading requires more labor for machining setups and thus more cost.

Got the code and ordered - thanks to djozz and Sofirn for making this possible!

i see they are avail on Amazon US now :slight_smile:

Can Berry send me the code to Amazon US, as there on there now.but not shipping till Sept 25th. THANKS

Is known how many amps are drawn from the 4 batteries?
5k Lumen - that will be somewhere above 10 Amps easily

Maybe I finally have a place for the 3400mAh protected Panasonics…

I think you will have to wait like everybody else until the codes are sent out.

That is not a good battery for use with a Q8.

Typical Q8 with high drain cells is about 15A total. With bypassed springs about 20A. With 3400mAh protected Panasonics maybe 9A?

More like 6 to 7A for the NCR18650B’s

BLF Q8 In turbo it takes 4A from the cell, which is 16A in total. Measured by a clamp meter.

Thanks, I know it will be really low due to their old chemistry that has high internal resistance and big voltage sag plus the protection circuits add even more resistance.
