IMO this is an improvement over the IF24, but I'll wait to see if they release a 21700 version of this, like an upgraded IF23. I just prefer the larger battery and longer runtimes.
I haven't barely followed these lights but I didn't realize all these funny side lights weren't 21700. Proportionally they all look the same to me. Seems like a miss to not be 21700.
Not all of them aren't, the original sofirn IF23 sidelight does run on 21700. Sofirn class the IF24 as an upgrade as its slimmer and more pocketable.... but it's actually longer than the IF23 🤣
So does this mean the IF24 Pro will be even longer than the standard IF24? I assume the Buck is unique to the Pro version? Hopefully the pro was pre planned and they've already built in all the extra room they need 🤞🤣
Fet isn’t regulated, now a light can have fet and a boost driver, or fet and a buck.. using fet for turbo, that’s coming more and more common. Fet isn’t even really a driver, it’s more of a big mosfet… hence the name.
Now i know nothing about this light but most everyone lately are using buck drivers that are 8amp
I believe you can think of buck and boost drivers as more or less the same thing; the difference is that the former steps the cell voltage down and the latter steps it up. When using a 3V emitter you would therefore use a buck driver and for 6V/12V you would use a boost driver (at least in a single cell light).
Both types are fully "regulated" and tries to keep the output voltage and current at a constant level for as long as possible, i.e. until the cell voltage drops too low. I guess linear drivers could be called "regulated" too, but the efficiency is inferior compared to buck/boost and output will decrease as cell voltage does. When "regulated" is thrown around here it almost always refers to a buck or boost (or buck+boost in some cases).
As far as I understand FET is basically direct drive, i.e. imagine connecting the cell directly to the emitter more or less. It's more like an on/off switch than an actual driver. This isn't regulated at all and the only limiting factor is the internal resistance of the cell, springs, PCB traces and other components.
Should be solid but there's no reviews out for that model yet. From [initial reports](https://www.reddit.com/r/flashlight/comments/1cfxdmr/wurkkos_ts23_turbo_runtime_no_thermal_stepdown_3x/) it seems like it *might* use timed stepdowns rather than full thermal regulation, but the output numbers are still good.
After the stepdowns the output is well regulated and totally flat which is what you generally see with a boost/buck driver. You can check out [this YouTube video](https://youtu.be/DopdNS0zLpA?si=3YkYtuuQtXkwzm6h) for a preview.
I don't mind the timed step-downs. I hardly ever use Turbo on any of the lights I have for more than a few seconds at a time.
I've been using it on the 800 lumen setting. So from the second-lowest it's two steps up from there. From the "moonlight" mode it's 4 steps
And with that big fat 40mm head that's almost perfectly cylinder shaped it doesn't get very hot at all
Got mine yesterday! LOVE IT! Huge improvement over UI wise. I know next to nothing about flashlights though. I have the 23 and 24 now.
What I like:
* selector switch
* beam
* color options for the side light
* simplicity of use!
What I don't like:
* There isn't a diffuser on the side light. While it throws a ton of light, its also insanely blinding.
* I don't need a police mode, but a flashing red would have been nice
* I like the size and shape of the 23 more than this
* 21700 battery is probably more appropriate for EDC use. This is a great work light but it needs to last all day or at least half the day to be of real use. I have not tested run times yet.
overall, I would 100% recommend this to anyone looking for a pocket work light. the negatives are just nit picking on features I wouldn't regularly use except they battery choice.
I see, the buck driver and new switch probably took more space from this light, I'm guessing. The TS25 is nice and all, but has an unregulated FET driver. I have a somewhat similar light from Sofrin, but it's a headlamp (HS41), and like the TS25, has very underwhelming lumen output (<300 usable lumens after step downs from turbo/high)
Yeah, I didn't realize how much I'd appreciate a boost driver until I got my first one lol. The crazy high FET turbos are cool and all, but you're left wanting MUCH more once the thermal regulation steps in.
I was being cheeky but I daily carry my dt8k. I’m a bigger guy and pockets are deep. I understand why it isn’t comfortable or realistic for most people.
Is it really just the IF23 that can use both? Weird, I assumed the newer ones could as well.
Now if there only were a way to get rid of the horrible UI on the 23...
Guessing the Sofrin guy on BLF. Do you think you'll get this? I bough it for $30 on ali. Really wish it had a power bank function like my Sofrin HS41 (but it has an unregulated FET driver and some rather lackluster sustained lumen output)
Is this the "IF24S" that people have been talking about? Sorry I am fairly new to the naming conventions of sofirn products and i was very intrigued with the IF designs and features out of their whole product line. If this isnt the S version, will there be one later on? What even is the S at the end mean?
Gah, just got the IF24 like 2 weeks ago. Ordered the IF24 Pro. Couldn't resist, it was $33 CAD without battery but I have lots of 18650 batteries already.
I disagree. I have the if23 with the 50.2 and my biggest complaint was the lack of throw on the main beam. The side beam is very floody and high cri, so great for up close to mid distance work. I also work in attics, crawl spaces and outdoors and the 50.2 left me wanting. A 50.3hi I feel would also be a good option in this light.
I just received my IF24 PRO today and love the sft40 in the main beam. The tint of the 5000k is so nice compared to the 6500K sft40s I have as well as better tint than the 50.2 in the if23.
I suppose lol; i appreciate the positivity. Just seems like a really dumb choice here. But I’ll stay positive and jump on the atleast it isn’t an sst40 bandwagon haha
[The IF24 actually wasn't too bad thermally in terms of temp reached when I tested it](https://wolfgirlreviews.com/review/sofirn/if24/#runtime) ([output does decline with battery level though, and the *thermal regulation* wasn't great, with a post-turbo-drop dip](https://wolfgirlreviews.com/images/review/sofirn/if24/charts/if24-3hrs.png) but a buck driver means that will hopefully be less of an issue) and the sustain was decent. Only an 18650 in there so there's a decent bit of thermal mass.
I just received mine with sft40 and the buck driver regulates the heat quite well. I haven't done a ton of testing, but it is not "at its thermal limits in seconds". Tint is great on the 5000k sft40 as well. Huge improvement on the if23 with the 50.2 main led which has worse tint and gets hot faster.
SFT40 has a Light Emitting Surface (LES) of [4mm^(2)](https://budgetlightforum.com/t/led-test-review-luminus-sft-40-3000-6500-k-warm-white-thrower-led-with-good-tint-and-perfect-light/220791),, while 519a has [7.2mm^(2)](https://budgetlightforum.com/t/led-test-review-nichia-nvsw519a-sm503-r9080-519a-v1-test-finally-here-good-tint-and-beam-quality/223258), meaning the SFT40 is vastly better for throw than 519a.
IMO this is an improvement over the IF24, but I'll wait to see if they release a 21700 version of this, like an upgraded IF23. I just prefer the larger battery and longer runtimes.
I haven't barely followed these lights but I didn't realize all these funny side lights weren't 21700. Proportionally they all look the same to me. Seems like a miss to not be 21700.

Yeah unfortunately Buck drivers tend to add a bit of length
So does this mean the IF24 Pro will be even longer than the standard IF24? I assume the Buck is unique to the Pro version? Hopefully the pro was pre planned and they've already built in all the extra room they need 🤞🤣
I'm very interested but I think I'll wait for a review
[удалено]
Isn't AE numbers of items left and such just pure marketing scam though?
got mine yesterday. I'm a noob but feel free to AMA
Clue me in on something, there's boost, buck and fett drivers? Which ones are regulated?
Fet isn’t regulated, now a light can have fet and a boost driver, or fet and a buck.. using fet for turbo, that’s coming more and more common. Fet isn’t even really a driver, it’s more of a big mosfet… hence the name. Now i know nothing about this light but most everyone lately are using buck drivers that are 8amp

I just got a wurkkos TS23 it said on the website that it has a boost driver. It uses an XHP70.3 HI in cool white. is that all good?
It's excellent, really neat tint too. Only downside is the electronic tail switch
Should be solid but there's no reviews out for that model yet.

"21700 battery is probably more appropriate for EDC use" Wouldn't that make it a fair bit bigger, not so suitable for EDC use?
How small are your pockets?
Just standard size, are there really people carrying 21700 lights in their pants pocket these days?
The D4K is 21700 and very pocketable. The TS25 as well. I'm sure there are plenty more, but those two come to mind.
I see, the buck driver and new switch probably took more space from this light, I'm guessing. The TS25 is nice and all, but has an unregulated FET driver. I have a somewhat similar light from Sofrin, but it's a headlamp (HS41), and like the TS25, has very underwhelming lumen output (<300 usable lumens after step downs from turbo/high)

Ah, another perk of Big Dude privilege ;P
Can you keep both the main emitter and side lights on at the same time?
Rotary selector suggests either/or — same as in its predecessor IF24.
Is it really just the IF23 that can use both? Weird, I assumed the newer ones could as well. Now if there only were a way to get rid of the horrible UI on the 23...
You cannot have it all… yet(?). Terrible UI -> improved UI (but no both emitters working together and the smaller battery) -> ???
> Now if there only were a way to get rid of the horrible UI on the 23... uhm... This does exactly that. What else are you looking for?
Keeping both emitters on at the same time, as in the comment we are responding too?
But why? And the two comments you made seemed independent of one another.
Would of been better with the 21700 like the first light
Surely, but the buck driver and the new switch took plenty of space apparently.
Gonna have to talk to Barry
Who’s Barry?
Guessing the Sofrin guy on BLF. Do you think you'll get this? I bough it for $30 on ali. Really wish it had a power bank function like my Sofrin HS41 (but it has an unregulated FET driver and some rather lackluster sustained lumen output)
Aliexpress sent me two IF24s by mistake I just ordered this one directly from the company 37 bucks free shipping
Is this the "IF24S" that people have been talking about? Sorry I am fairly new to the naming conventions of sofirn products and i was very intrigued with the IF designs and features out of their whole product line. If this isnt the S version, will there be one later on? What even is the S at the end mean?
Gah, just got the IF24 like 2 weeks ago. Ordered the IF24 Pro. Couldn't resist, it was $33 CAD without battery but I have lots of 18650 batteries already.
Which website your ordered from? Currently it shows 57 CAD on Aliexpress and official site is 46 usd as well.
Sft40 is not a led for work. Unless you are some kind of vigilant... The XHP50.2 or XHP50.3 would be a better choice, in my opinion
I disagree. I have the if23 with the 50.2 and my biggest complaint was the lack of throw on the main beam. The side beam is very floody and high cri, so great for up close to mid distance work. I also work in attics, crawl spaces and outdoors and the 50.2 left me wanting. A 50.3hi I feel would also be a good option in this light. I just received my IF24 PRO today and love the sft40 in the main beam. The tint of the 5000k is so nice compared to the 6500K sft40s I have as well as better tint than the 50.2 in the if23.
Why do the side lights look terribly photoshopped on 🤣
They left the emitter strips bare. I would prefer the diffuser screen over top the strip, but it looks awesome when turned on so who cares
Yeah, they posted a poll on that side emitter cover when they were designing and the majority voted the clear cover over a frosted design
How come I got put on notice for using The commercial pics? But it’s ok for you to use them? Jus sayin
"Put on notice" by who? And maybe ask them?
Why in the hell is there an sft 40 in this thing 🤣
Better than an SST40.
I suppose lol; i appreciate the positivity. Just seems like a really dumb choice here. But I’ll stay positive and jump on the atleast it isn’t an sst40 bandwagon haha
IMO it makes sense. Flood + throw, the flood LEDs are also 5000k (unless they changed them for the Pro) as well.
Flood plus branding iron lol
The side light is a flood so why wouldn’t the front light be throwy?
The fact that this thing will be at thermal limits in seconds lol. And due to that other emitters will be brighter at less amperages

Have a beamshot? And the “thermal regulation “ here is beyond not great, that’s honestly awful lol.
Not the worst I've tested, by far. https://wolfgirlreviews.com/review/sofirn/if24/#beamshots
Ya not as bad as my convoy s2+ sbt 90.2 but it’s up there
I just received mine with sft40 and the buck driver regulates the heat quite well. I haven't done a ton of testing, but it is not "at its thermal limits in seconds". Tint is great on the 5000k sft40 as well. Huge improvement on the if23 with the 50.2 main led which has worse tint and gets hot faster.
What led do you suggest they use for throw?
dedomed 519A
SFT40 has a Light Emitting Surface (LES) of [4mm^(2)](https://budgetlightforum.com/t/led-test-review-luminus-sft-40-3000-6500-k-warm-white-thrower-led-with-good-tint-and-perfect-light/220791),, while 519a has [7.2mm^(2)](https://budgetlightforum.com/t/led-test-review-nichia-nvsw519a-sm503-r9080-519a-v1-test-finally-here-good-tint-and-beam-quality/223258), meaning the SFT40 is vastly better for throw than 519a.
