Where is Sofirn’s poll?

Real Sony cells came today, complete with an AWT charger. 2 cells and charger, shipped, for $19.95…

BUT, where the 2 Samsung 30T made 12,488 lumens in my triple MT-G2, these make 9,485 lumens. A drop of 3,000 lumens! The pair of Samsung’s allowed 27A to flow, these two Sony’s only allow 16.8A. Internal resistance on these “new cells” is 48mOhm according to my MiBoxer C4-12 charger.

Edit: FWIW, new Shockli 5500mAh 26650 button tops also only yield 16.7A.

BlueSwordM · 2018-12-17T21:17:02.000Z

Yeah, let’s not forget that the 30T are new 40A cells, while the Sony 26650s are old 30A cells.

DB_Custom · 2018-12-17T21:38:14.000Z

I just tested new Shockli 5500mAh 26650’s, the newest ones with the labeling to be read with the cell standing on end… same 16.7A. These are rated 20A continuous and 30A pulse

In my modified D4S, a Golisi cell gives 19.22A, the new Sony yields 15.46… this is of course a single cell to 4 Samsung LH351D W6 5000K emitters. Edit: For realism, the Shockli does 15.06A in my D4S, so the new Sony actually beats the highly regarded Shockli, albeit with literally half the capacity.

Sorry, I forgot to add the link. Here it is:

Andúril 2 coming to Sofirn - The general Sofirn development thread LED Flashlights – General Info

First time to try this google tool. Hope it helps collect your ideas. Please let me know if anything wrong.

Tally-ho:

There is no driver’s retaining ring on the final prototype sketch, does it mean that it will be glued ?
As glued driver is the new sofirn’s trend, i’m a bit worried as it will be another absolute “no go” for me again if they are doing so with this one.

Answered a long time ago.

Thank you. The L6 and S70 are partly so popular because they are easy to take apart, modify and upgrade. The only people who like glue are engineers who don’t have to take them apart later on. Lol

They said the SP70 can be used with flat tops, but I really doubt that.

We just need to use common sense. The batteries are in series from head to tail. So the ends need to stick out enough that they make contact. As there are no standards for Liion cells you have to evaluate every choice. Some flat tops are kind of tall and make contact, some aren’t.

Sofirn said their 26650 5000/5500mah and 21700 4000mah cells are tall enough to touch, even though they are not button top.

Besides the cool white tint, they prefer, its the bigger “no go” for me, too.

They said 5350K to 5700K.

This is due to 4 years of chemistry improvements. Ya gotta love these newer batteries.

May be just the same old one if he measure at 0s

Sorry, but it’s 6000K - 6500K

Would have really preferred 4500K-5500K range, hopefully they offer other options in the future.

Lux-Perpetua:

Some essential information I got from the SP70 manual:

According to the manual the flashlight is designed for 26650 and 18650 (with adapter sleeve) only. For batteries, maximum diameter is 26.9mm and maximum length is 71mm. I asked Sofirn about 21700 compatibility. They said it’s working but not recommended as spring compression will be very tight. I have some doubts as flat top 21700 would not make contact out of the box, so one needs to solder a blob onto one’s unprotected 21700 cells or use a neodym magnet as protected batteries might be way too long.

There is no information if flat top or button top cells need to be used. I highly recommended to add the information to use button top cells only but Sofirn says it works with both types.

Maximum intensity is 89,733 cd or 687m @ 5,500 lumens. The ANSI/NEMA FL1 test was performed with 2x 26650 with 4,800mAh.

The SP70 is rated with IP68 ingress protection.

The lens is toughened mineral glas but without AR coating.

ATR (advanced temperature regulation) will be triggered at 60°C on the driver. For comparison: The C8F triggers ATR at 50°C and the SP33 XHP50.2 triggers ATR at 55°C already.

There will be a two-stage stepdown from Turbo: After 3min on Turbo (5,500 lm) the SP70 steps down to High (3,000 lm). After 30min there will be a second stepdown but there’s no information to what level it will be reduced.

It will have a power indicator to show the battery status and to work as a locator LED when in standby.

The SP70 will have two mode groups (group 1: 6 stepped modes, group 2: ramping) that can be changed with 6 fast clicks.

It can also be locked-out electronically by 4 fast clicks.

Strobe will probably be activated by 3 fast clicks but I need to ask Sofirn again as it’s not mentioned how to activate it.

There is no Strobe but only Beacon which is decided when the project started. People say Strobe is not a must. Furthermore, a strobe-enabled flashlight will need a confirm or register (something like that) in EU in 2019.

Lux-Perpetua · 2018-12-20T04:36:29.000Z

Thank you Barry! I was only confused as I found this in the specification in Sofirn‘s SP70 manual:

„Mode Memory : Last mode remembered - it memorizes the last brightness level used in the general modes (except Strobe)“

I guess Strobe needs to be exchanged by Beacon then.

Is this what Sofirn said they were going to use?

So we are moving from 2C/2D to 1C/1D?

Is it gonna be available as a host? I’m not really interested in CW…

I do not believe that they sell it as host, e.g. because of the glued driver and the lack of retainer ring.
Their C8F is for sale as host. They are not a company who does not sell hosts at all.
