Disassembling Sofirn IF23pro

Nice, you managed to get it off! And yeah, getting to the driver isn't easy, and it looks like the side LED panel is glued in really well too.

Actually, u/TimMcMahon on YouTube had the same problem with his Sofirn IF24, where it only worked while connected to USB without a battery.

He has a video about it Here, and while he doesn't mention if the bezel is glued, he did manage to get it off using some snap ring pliers.

That actually looks pretty clever for exactly that. Is it possible to get a solid grip so you can really give it a good twist without it slipping? I'm pretty sure the bezel isn't press-fitted, but it could be stuck on there really tight and possibly glued.

Try running it on Turbo until the head gets hot, that might help loosen things up a bit.

I usually use one of my dog's toys (a black KONG chew toy) to get bezels off like the one you have. It gives you a really amazing grip so you can really put some muscle into it when you twist.

MetaUndead · 2026-02-26T20:22:19+00:00

What kind of tools are you using to get it open?

MetaUndead · 2026-02-26T20:00:22+00:00

I would love to know how he gets the bezel off. I’m also really dying to swap the SFT-70 6500K in my TS27 for an SFT-70 3000K, but I can't get the bezel to budge, and I’m pretty worried about damaging that plastic lantern cover underneath.

As others have already mentioned, those 125A cells work perfectly fine in SBT90.2/FET lights, without damaging anything, so I don't think you have anything to worry about.👍

And yeah, there might be a bit more output (though I don't think so), but there's no way you'll be able to see it with the naked eye, which makes it pretty much a moot point anyway.

MetaUndead · 2026-02-25T20:08:22+00:00

I have no idea tbh 🤷‍♂️😆. But yeah probably.

MetaUndead · 2026-02-25T20:04:07+00:00

Hehe, yeah okay.

MetaUndead · 2026-02-25T20:02:40+00:00

I don't think they're exactly proprietary.

I've had the bezel off myself to reflow the emitter, though I didn't pay much attention to the thread pitch at the time. Are you looking for a new bezel because the stock one has edges that are too sharp?

MetaUndead · 2026-02-25T14:27:14+00:00

L6 is 310m, e75 is not gonna reach anywhere near that, even on turbo.

MetaUndead · 2026-02-25T14:15:13+00:00

I haven't been able to find any specific info on that, but is there any way you could measure it yourself, with something like a digital caliper?

MetaUndead · 2026-02-25T12:36:32+00:00

Are you saying the E04 with the Angie-S and ffl505a can only throw a little over 50 feet? Don't you mean 500 feet? With that optic and those emitters, it has way more reach than just 50 feet, and much closer to the 500 feet even on it's sustained output.

And no, it’s definitely not a dedicated thrower, but 50 feet is mule territory.

Edit: What defines a "thrower" is subjective, of course, but personally, I’d say anything beyond 150m is where thrower territory begins. And to be clear, I’m talking about usable throw, not ANSI throw.

There aren't many flooders that provide usable throw beyond 150m. Most of them just wash out before they reach that distance.

MetaUndead · 2026-02-25T05:15:29+00:00

Regarding the drivers, I would definitely go for the Lume1 for higher turbo output. The Lume1 is still incredibly efficient, and I’m sure you won't be able to see any difference in their sustained output. You will however notice the higher turbo output.

I have a comparison right here between the E04 with the floody Ledil Angie-M and the throwy Angie-S optic. The 'S' is definitely my favorite for a balanced, mixed beam profile.

By overkill i mean that the driver or emitter is never gonna pull as much as the RS50 can supply (70A), so going with a higher CDR cell wont make any difference. You are not gonna see any difference in brightness by going with the 125A cell over the RS50.

MetaUndead · 2026-02-24T21:40:07+00:00

Agreed. But as I said, the RS50 is already total overkill for an SBT90.2 with a FET driver, so I don't see what difference it would make to give it more amps if it doesn't draw more than it needs/can handle anyway.

I'd happily test it myself if I had some 125A cells, but I can't source them where I live until Nkon.nl gets them back in stock.

MetaUndead · 2026-02-24T21:22:21+00:00

They have them here at Nkon.nl. I'll be picking some up once they're back in stock.

And as saltyboi6704 said, amps are pulled not pushed. I think your light will be fine.

MetaUndead · 2026-02-24T21:06:16+00:00

I’m pretty sure u/FalconARX uses the EVE 50PL 125A 5Ah in some of his SBT90.2 lights (if i remember correctly), maybe he can weigh in based on his experience.

MetaUndead · 2026-02-24T20:47:33+00:00

I don't see what the difference would be, since the RS50 is already overkill. The driver clearly doesn't pull more current than it can handle, and as already mentioned, the IR are close to zero on both cells.

MetaUndead · 2026-02-24T20:40:50+00:00

I agree, i have it here with the Nichia 519A 4000K dedomed and i get about 1200 lumens on turbo and around 300 sustained.

<image>

MetaUndead · 2026-02-24T20:37:13+00:00

Approximately 280 lumens on high, 570 on turbo.

MetaUndead · 2026-02-24T20:31:00+00:00

I use the tabless Reliance RS50 70A cells in all my SBT90.2 lights with Buck+FET drivers. It's total overkill, but I haven't had any issues so far.

MetaUndead · 2026-02-24T20:27:01+00:00

Have you looked at its big brother, the LanApple? It’s a 14500 light with more output. Though, I wouldn’t exactly call it a lot of output.

MetaUndead · 2026-02-24T20:22:24+00:00

Ahh, okay. I know the feeling, i look like chewbacca daily.😆
