Sofirn SP35 - SST40, 21700 size, buck driver

Hello everyone,

Sofirn is recently launching more and more new products. Some of you may have already noticed a new SP35 flashlight (among others). Actually, it is not listed anymore right now but it will be back soon again. Smile

https://sofirn.aliexpress.com/store/new-arrivals/2933049.html

Some first specs Barry was so kind to share with me:

  • 21700 battery format
  • compatible with 2x CR123A
  • Luminus SST40 5.000K / 6.000K
  • constant current buck driver
  • USB-C rechargeable
  • e-switch side switch
  • Sofirn's proprietary UI as used in SP33 V3
  • improved ATR technology

Here's a first runtime graph courtesy by Sofirn which shows a nice constant regulation of SP35 at 550lm. SOP is headed for end of November 2020.

I’d love to see Sofirn update the old SP35.

I came across this: https://www.aliexpress.com/item/1005001640015568.html

Any updates? There’s no option for CCT. I want it in 5000K (SST-40). It’s exactly the kind of outdoor light I’ve been looking for.

EDIT: According to Sofirn on AliExpress, it’s 5000K. I put in 1 order and I’ll add a comment about my thoughts.

EDIT 2: About 29 hours remaining and the order still hasn’t been fulfilled. I’ve never had an order from Sofirn take longer than 2 days to get shipped out. I’m starting to wonder if they’ve even made any to actually sell. I’m thinking about extending the processing time.

EDIT 3: Just shipped out.

That’s troubling – have you tried sending them a message about it?
The listing doesn’t exactly inspire confidence (only a single rendered image) – so it’s possible they rushed out the listing with insufficient stock.

I waited and just got the shipping notification. It seems like it’s the real deal.

I’m getting sent one for review with my latest bulk order. It was listed on AliExpress before it was released, approx 2 weeks beforehand, not entirely sure why they do that, maybe for 11.11 sale.

Had a terrible issue with a floating shelf, unless you mean the SF11 which uses 4x AA’s

Fingers crossed you get the light without any further delays!
It’s nice to see Sofirn put out another light with regulation. These days their newer revisions seem to have largely FET drivers…

Ditto. I was prepared to order another SP32, but will wait to see how this turns out. Hopefully, it will have a beam that is somewhat balanced, and isn’t too throwy.

I won’t be in the clear until the tracking gets updated. Sometimes, sellers accept an order with a placeholder tracking number that’s later replaced once the item is actually shipped out. I don’t know if Sofirn is doing that now but if it happens, then I won’t be surprised. I would’ve extended the processing time anyway.

Also, I’m not worried about quality. I’ve used multiple Sofirn lights and I’m happy with the build quality.

That’s what I’m hoping for too. It’s using a domed LED and a decently sized reflector. The “200-500 m” lighting distance figure makes me wonder about the type of reflector used. Will it be smooth or orange peel just like the SP33V3? I’d be fine with either one and if I had to take a guess, I’d go with orange peel. Sofirn seems to love that for their bigger lights.

EDIT: “Shipment cancelled”. I guess it’s not ready yet.

I’m not going to get my hopes up. Upon further thought, it looks like the SP35 will basically be a 21700 version of the SP31, without the tail switch. The head and tail cap designs mostly resemble the SP31, suggesting that is the evolutionary path is follows, not that of the SP32A.

That doesn’t preclude it from being better balanced, but we’ll see.

I wonder if that pocket clip will fit the IF25 body.

The Wurkkos HD20 clip fits the IF25/IF25A body but gives a tiny surface scratch putting it on, no real issue though. Sofirn can sell it if you ask them

Those of you who have ordered an SP35 and have been sent tracking numbers, I highly doubt it’s been shipped. As a dealer for Sofirn I was being sent an SP35 for review, but have been told they have an assembly issue, so the units aren’t yet ready.

I really wish Sofirn would list on AliExpress etc with a Pre-Sale notice, not saying they’re in stock.

That’s what happened to me. It says “Shipment cancelled.” I can’t say I’m surprised because it’s a very common tactic. They’d rather secure a sale and have the customer wait than list it when it’s actually ready. I’m gonna give Sofirn 2 months from the order date to have it delivered to me. If it takes longer than that, then I’ll never buy a light from them again.

That’s a bit harsh. Just don’t buy a model that’s brand spanking new with only a computer generated image

Really glad to see “improved ATR technology” listed, as that’s been a weak point in recent memory.

Overall, I like a lot of what I see here! I think it’d be great if the sustained output was a bit higher. And I’m sure it’s too late in the game for a change like this, but I much prefer the silicone-button side switches with the switch mounted on a separate board and held in with a retaining ring. I know Sofirn likes their T-shaped driver boards with mounted switches though.

I don’t like the T-shaped driver either, the SP40 is an odd design. The driver extends up and is soldered directly onto the switch board. I would expect it to be a lot less durable.
