A lot has been said about this light, figured I'd add my 2 cents.

Best feature? The UI. Lets you make the light your own

Worst feature? The UI. Scares people away as being to much

Don't fear the UI. As it comes with the default settings, it a great light. Learn the UI & you can make it even better.

Default settings are very inclusive. From OFF you can start from a low of 1L or your last used (memory) level or up to 3800L+(depending on battery). From OFF you can ramp up & down from a low of 1L to a high of about 2000L either in steps (7) or seamlessly. Run times are good at under 500L levels & there isn't much of a heat issue at that level either. Charge the battery(internally w/usb) click it on, hold for ramping, click if off. You never need to do anything else to have a bright, small, useful light from the start.

BUT if you want to make the light your own, if you want to get the full potential from the light .. learn the UI. There are several very good YouTube videos out there that will walk you thru each feature step by step. And if you mess up? So. If you do somehow "mess up"; the default settings can be reset in about 3 seconds. YOU CAN'T BREAK IT (unless you take it apart & try to "flash" the chip)

The included battery doesn't let the light perform as well as it can as 3rd party testing hinted. It's true a Samsung 30T cell will boast your turbo lumens by a claimed 900L. I did see an increase but can't confirm it was 900L, but it was noticeable in my lights (yea I have 2)

The 6500K light looks brighter at every known level when compared to the 4000K light. The 4K light looks better when colors matter. Neither is glaring or even very noticeable until you compare them side by side. The light is very compact for a 21700 format. The only thing that keeps it from being a great EDC is the head size. It's a bit big for jeans pockets but works fine out of cargo pants or a jacket pocket.

Everyone should have this light. It does nothing badly & more than a few things really well. Figure in the $35 cost & it gets to be a hard deal to equal much less beat

anduril is the reason my sofirn lights are my go to lights right now. Currently carrying my sc31 pro but if wearing my big coat or carrying a bag I carry my If25a.

The only customising I have done to all my anduril lights is turn the switch light off when off and when locked out. And have the ramping set to stepped with mode memory set to the around 100 lumen setting.
To me the ui is perfect.

The batteries are not proprietary but oddly the supplied battery provides excellent run times but not peak lumen levels

Just got the clips that are made for the light but not included .. wtf? Got 1 for each of the lights & man do I like'm. If they had come with the light(s) my unicorn search may have been over a lot sooner. Look for the clips in the accessory link at Sofirn. They have belt pouches for the different lights at a cost that can't be beat ($0.01) plus a couple of under $25 lights that are worth looking at. Just don't be in a rush shipping can take a while

I have a lumentop clip on mine, did not know you could get clips for the If25a from sofirn, just ordered a magnetic tail cap for my sc31 pro too, and some short tubes and a couple of type c to type c charge cables.

Got bored so I did a run time test. Fully charged Samsung 30t, rested for 1hr before the start. Light was memory set to factory claimed 125L level (first ON after replacing the battery) Light indicated 4.2v to start & 3.0v at the first step down. It looked to be about a 50% reduction. I didn't run to shutdown.

Total time to step down was 8 1/2hrs. The light never got warmer than room temp. It wasn't cooled & it was used in 3 different rooms. Test was done on the 4000K version of the light & the battery & light had been paired thru 3 charge/discharge cycles before today. Spec on the 30T is 3000mah as I understand it so a 5000mah 21700 should/could show a 30-50% improvement in run times.

Tested. Trusted. I really like this light

I have many more expensive lights but I could happily live only owning my sofirn If25a and sc31 pro as they are the only torches I really use other than my headlights. All my other lights with last use memory mode I can stop myself cycling through modes when I first turn them on just to check. Where as as I can set the mode memory manually in my anduril lights I don’t need (feel compelled) to check what mode it is in. I’m I the only one who does this?
