Sofirn IF30 (Multi Beam, TN-3535 & SFT40, 32650, USB-C, Powerbank)

I received the IF30 for the review from Sofirn. If you like the IF30 and are interested in purchasing it, there’s a link with a coupon code at the end of the review.

The IF30 is a dual beam flashlight, featuring a Spot Beam (generated by a SFT40 emitter) and a Flood Beam (generated by 12 TN-3535 LEDs). Both beams can be combined, to obtain a combination of flood and throw. You can control the light via a rotary switch and an electronic button. The light is powered by a 32650 lithium ion battery, included, and is USB-C rechargeable.

The IF30 is available in cool white, in the future a neutral white version will be release.

The IF30 comes in this box

The content of the box: IF30, Lanyard, spare o-ring, Battery, USB-C cable and the IF30, of course.


The IF30 weights 414.1 grams, including the 151.2 grams of the 6500mAh 32650 battery.
The light measures 129 mm in length, with a head diameter of 62 mm (39 mm at the tailcap).

The view of the emitters. At the center, the throwy SFT40, and around it the TN3535 in a flood arrangement.

The electronic switch is single stage, with a good feedback. Not only it can be pressed down, but it can also be rotated freely in both directions (see the arrows). At the center, there’s a LED battery indicator (when using the light: green>50%, red>30%, red flashing<25%, when charging the light: red = charging, green= charged).

The tailcap is flat, allowing tailstanding, and has white clear engravings.

The threads are square cut, anodised and allow for a physical lockout of the IF30.

The contact point for the battery at the head is a raised golden button. So flat top and button top cells will work fine.

At the head there’s also the USB-C port for charging the battery.

Note that the rotating ring doesn’t give you a linear brightness change, but you will change brightness through a series of levels. Sofirn doesn’t specify the number of modes available, from my testing with my luxmeter, I counted 24 levels.

Output & Runtime
Please note that I measure brightness at the startup, as you can see from the third plot, all tested levels do get brighter once the light is on for a short period of time. This does not regards only turbo modes, but also other levels, but is not noticeable by eye.



in this last plot you can see more clearly how well the thermal regulation works, there are no timed stepdowns.

My thoughts
The light is well built and finished.
I like the interface, with quick access to turbo and to low, turbo and last used mode. Changing between the beams is easy.
Regarding the beams, as you can see from the beamshots the spot and flood beam are quite different, and effectly complement each other well: if you have the flood mode on, and you need more throw, then the spot or the combined beam will defenetly give you the light you need.
The rotating ring works well, and I like how they implemented an electronic lockout to avoid accidental activation. I like the stiffness that it has regarding the rotating movement. However, with 24 levels to go through, I measured 12 levels per each complete rotation, so it will take a wile to go from a low level to a very high level (or the opposite). Also, there’s no visual indication of where you are at with your level (are you at level 5? 10? 22?).

The light takes advantage of the 32650 battery capacity to give the IF30 a sizeable runtime (and powerbank functionality). The light doesn’t feel particularly heavy or bulky (would fit easily in one of the pockets of my winter jackets), I think that if you are looking for a light that can provide you with both a flood and spot beam, have plenty of runtime and is aggressively priced, the IF30 can suit you.

I like that the light will also available with NW tint, and works with non proprietary batteries.
I would have liked a sheath to come with the IF30.

I seem to be able to only find one version on @Sofirn website - not sure which one. I’d be interested in the warmer/natural version (i.e. some 5000K). Does it exist?

Sorry there is only one version of IF30, there might be some misunderstanding, I’m gonna check it.

Update: Apparently the NW version is not available yet for purchase, but @Sofirn plans to release it.

Buck driver?

@Budda: Would you have a picture of the flashlight in hand, for instance, or against some other popular flashlight to ascertain the size?

p.s. Where would one get an extra battery like this? I looked at Vapcell but couldn’t find it.

p.s.s. Found the discharge curves of an od Vapcell-wrapped 32700 cell. The curves are amazingly flat. This makes me wonder if with this the driver type makes much difference when a battery of this size is being used?

I will take your requested picture ASAP
The behaviour of a 3.2 v lifepo4 cell, like the one of the on reviewed in the link you posted, is quite different a 3.7 li-ion battery like the Sofirn one.
From my understanding, 3.2 v are much flatter in term of voltage across charge.

On Sofirn website there is a mention of an autolock after 15 seconds of inactivity. Turning the switch-dial is supposed to unlock the light. Could you confirm it? Is the Autolock compulsory or can it be deactivated somehow? Thanks!

yes, the lock it’s automatic, and theres no mention of the possibility to turn it off.

1 Thank

Sorry for one more specific question: when the light is auto-locked and you turn the dial (Sofirn says 60 deg, so not that much), what happens? Does the light blink or double blink to let you know and stays off? Or it turns on at the memorised level/mode or the lowest, or something else?

when the IF30 is locked and you press the switch, the light blinks twice.
when you turn the ring enough to deactivate, the battery indicator turns on and then you have to click the switch. the light will turn on at the last mode.
