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

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.

Yes, this is what you get with good, high drain cells with no protection circuits.

NO not waiting…i deserve it first…all others can wait.lol…thanks man…i will wait…hope we get codes soon.

/\…. :+1: … :smiley:

For the cool white Q8, it makes sense to use NarsilM V1.2. It keeps the new Q8 faithful to the design of the old Q8, but uses an updated version of the firmware. The memory bug is not a major issue, considering that 2000+ old Q8 owners did not notice it.

For the SP36 and other new lights, I do not think it makes sense to keep using NarsilM. It is not really maintained any more, and it is not easy to update, so it may complicate the development process for new lights.

However, Anduril might make sense for new lights. It is intended as a newer, simpler, and more flexible replacement for Narsil… and its FSM code base makes it easy to create other custom interfaces if desired. Much like how a computer operating system allows the user to choose hardware and software, running many different applications on many different computers, FSM allows people to run many different interfaces on many different flashlights.

I would also recommend including Lexel’s firmware flashing port on new drivers. It allows people to install different interfaces fairly easily. Sofirn could potentially even allow the customer to choose their favorite interface at time of purchase, and flash the desired firmware to the light before shipping it to the customer.
