[Review] Sofirn IF25A flashlight: $34 (discount code available) with 21700 cell, 3800lm, USB-C, Anduril [pic heavy]

Need a little opinion here- I don’t usually stare at the business end of a quad emitter light, but it seems that only 2 of the 4 emitters of my IF25A are working. Do I claim warranty or can I pop the bezel open and try to see if anything is amiss? Only 2 diagonally of the 4 are giving out a beam. It’s useable but just doesn’t feel right. Either in moon, normal, strobe, turbo, I can’t get any reaction out of the other 2 emitters.

I opened mine up last night to slice the domes. The board has one black and two red wires. Each red is linked to two of the emitters diagonally. It’s possible one of your red wires has disconnected.

It’s easy enough to open the light. My bezel wasn’t glued. Removing the optic takes a little patience because the legs are pretty firmly sitting in the board. Try gently prying up, little by little, on each of the four legs as you work around the optic.

If the wires look ok then it is likely the driver.

The IF25A ‘warranty unit’ arrived yesterday.

Kudos to Sofirn’s warranty for staying true to their product. I bought my unit from their Shopee store. I had to submit a short video reproducing the problem and was then given an option to either get refund or replacement. My reply was I’ll take whatever is easier on their part, since I’m conscious of whatever back end process the person on the other side will have to undergo. They opted to send me another unit.

The replacement unit arrived yesterday (no battery included). It’s a rather….interesting replacement. It’s like someone got the inside of a TS21 and stuck it in the body of a IF25A.

Why TS21? Well, it’s got that amber ‘on’ light AND that crazy blue light that shows up randomly (supposedly when going on blinkies and turbo, when voltage changes). 15c would say something like 2022 Feb, which is more recent than what my TS21 Nichia is showing.

Either way, I’m a satisfied customer.

As for the defective unit? Well, it’s still here. I don’t have the means to repair it (simple soldering) and I’m sure I’m not alone in saying that. Maybe I’ll try to fix it someday since I won’t be afraid of voiding anything anymore.

Time to bring the IF25A to its paces!

Awesome find Riccardo - thankyou

Greetings dear community.
I bought this flashlight with 4000K light and it is on its way to me.
Originally wanted a TS21 with Nichia. But then I changed my mind. I can’t explain why I changed my decision.
Do you think I made the right choice?
……

IF25A has a more usable light projection pattern, TS21 is much more floody. IF25A has a bigger head and has no clip, unfortunately.
I would also have chosen the IF25A anyway.

Got it, thanks. The clamp is not necessary for me. I rarely use it.

My IF25A arrived. After 15 clicks from the off position, there were so many flashes: 212212181614.
What version of Anduril is this?
….

A single short blink is a "0" and a single long blink is a "1" in the Version Check.

So "212212181614" is probably either "2022 02 08 0614" or "2022 02 18 0614".

Thank you. Rechecked, the first option turned out.
«2022 02 08 0614».
And what gives me this knowledge of the firmware?

More information about a particular version of Anduril would require finding where the source code is located and inspecting it or asking a specific question on this forum and hoping someone knows the answer.
