Sofirn IF25A received today!

My IF25A (4000K) came 2 days ago and so far I love it :heart_eyes:

It was an unpleasant surprise for me that the IF-25A does not have a battery status indication in the button, it just glows green until the flashlight is completely discharged. Despite the fact that when charging, a two-color indication is used. Why not do the same for discharge? I think this is a very big drawback of a modern flashlight.

Thanks for noticing that and pointing it out. It’s still so new that the typical detailed reviews aren’t out yet. The Sofirn site’s info on their product is very sparse. Or, I guess we just expect to know a lot about a flashlight.

The IF25A runs Anduril. The side button works similar to an “aux-LED” (on other Anduril lights) and can be programmed to 4 states: Off - Low - High - Blinking (Breathing), however, it’s not linked to battery voltage… Battery check mode can be done via triple-click from Off (will count the voltage). Granted, this is a slightly more “accurate”, but uses more time to check…

Three clicks from OFF. The first flashes are the Volt units, the flashes after the pause are decimal points. So, 4 flashes followed by 1 more after the slight pause means 4.1V. Click once to cancel battery check.

Thanks guys, I know how to check the battery status with clicks, but it’s not at all the same as seeing the remaining charge just by looking at the button.

Does anyone have both the 4000k version of the IF25A and a 4000k version of the D4V2 (either E21A or XP-L-5D)? How does the throw compare between the two?

Edit: If you have both lights (IF25A and D4V2) - which one do you prefer?

The IF25A comes with SST20, which will out-throw the E21A and XP-L-5D. It won’t out-throw XPL-Hi at 4000K. It’s worth noting the D4V2 is also available with 4000K SST20, in which case throw can be the same at equal outputs. (They’re both using Carclo quad optics, though I’m not sure exactly which one. But swapping them on the D4V2 is very easy.)

I have IF25A sst20 4000K and D4s xp-l hi 4000k and of course D4s with xp-l throw much more. But it would be incorrect to directly compare them, because they have different optics, IF25A shines much wider. The efficiency of LEDs is also different.
Overall, the D4S is better done with much more attention to detail. But much more expensive.

If I’m not wrong, the Sofirn IF25A doesn’t use a carclo quad. The Emisar D4s throws more than a D4/D4v2, no surprise that it throws more than an IF25A thanks to its Ledil quad with bigger optics.

Hello Zappaman, thank you so much for sharing your overview/observations on the Sofirn IF25A. That light with Anduril UI seems pretty good for EDC.

I’m ordering SC31 Pro from Sofirn Official Store on AliExpress. I was also considering the IF25A but decided to buy the SC31 Pro. I chose sc31 pro mainly due to its smaller size compared to the if25a.
From the specs it seems comparable in size to the convoy s2. i think it’s more ideal for full EDC. I have been EDC’ing Convoy S2 since 2017, not cumbersome at all to keep it in my jean’s pocket. .

The if25a is still in my consideration, I think it could be good for usage around the house/yard, for now i have convoy BD06 for that role.

Where did you guys get your IF25A? I got mine from the US Sofirn store (sofirnlight.com). The Anduril firmware version I got turns on the LED immediately when the button is pressed, which seems to be an older version of Anduril. The newer Anduril versions will wait to turn on the LED until after the hold-time is met. The newer version makes it much easier to hold long enough to get into moonlight without over-holding and starting to ramp.

Does the IF25A come with a newer version of the firmware? One where the hold-from-off to moonlight works better (i.e. LED doesn’t turn on until hold-time passes)?

first, i’d like to thank you and everyone for sharing your experiences with this light. it’s at the top of my considerations for a EDC in 21700.

looking at Battery Mooch’s data, the Molicel M50A outperforms the Samsung 50E (not sure about the newer 50E2)
the Samsung 50G looks to be the best of the bunch. i couldn’t find any for sale at the dealers i trust, but apparently Vapcell re-wrap these as the G50 15A* 5000mAh* (9.8A 4900mAh)

if using turbo AT ALL i would go with a sony VTC6A, Molicel P42A, or a Sammy 40T. for more practical use (<10A) the 50G/G50, 50E2, or M50A look like the better choice for runtimes.
batteries hate heat. running above (using turbo) their constant current rating will heat up the battery reducing it’s life and potentially cause thermal runaway. :open_mouth:

[off_topic] is that a cannon in your avatar? :+1:

Yes, that cannon is on Ft. Jefferson on Key West Florida. Worth the 2-3 hour tour if you’re there on a holiday. Western hemisphere’s largest brick and mortar structure.

BTW: I went from the Molicel to the 50G and never had enough run time to get the battery hot. Turbo ran fine on both and light gets hot way faster than (either) battery by the time you need a glove. I have the 18650battery Epoch re-wrap of the 50G. Great seller and great battery. The 50G button top is on sale there now too.

Ft. Jefferson. nice, would check it out if i’m near there for sure.

pulled the trigger on the IF25A 4000K, and a couple of VapCell G50s (comes with a case).
looking forward to my new EDC.

cheers :beer:

Is the If25A 6500k much greener than 4000k or both are similar in lower level?

Can’t speak to the 6500k, but my 4000K is rosy as all get out, especially below 50%. Turbo stays a lovely almost neutral white, with the slightest hint of pink…no green shift whatsoever.

Is it possible to install 4x W2’s

no, sir. Because the size of led is much different from SST20 leds
