Product Information

But what you lose in output you make up for in the light quality. I measured a warm 4243K colour temperature, with barely any tint and a high CRI of 95 and an equally impressive R9 of 91.

With the deeper smooth deflector the SC31 Pro has a decent throw. I measured 190 metres with an intensity of 9060 candela. That’s pretty close to what Sofirn lists as 10,000 candela and there’s still useful spill for seeing what’s right in front of you too. The other accessory it comes with is a lanyard, but the only place to attach it is onto the end of the clip, which is closer to the head than it is to the tail. This sort of makes sense, as it allows you to rotate the light between standard and overhand grips, but it doesn’t really allow for the cigar hold, and you wouldn’t want it dangling by this. Surprisingly, the bezel is not glued down. Not only that but the threads are lubed. Usually manufacturers don’t want you getting into the bezel, but on the SC32 it’s wide open, meaning emitter swaps will be a breeze. The UI here is ToyKeeper’s Anduril, which at this point is very well covered. I’ve reviewed other lights with it, too. Here’s ToyKeeper’s UI graphic: Advanced Temperature Regulation (ATR) technology: ATR will adjust the brightness level automatically when the driver temperature reaches a relatively high temperature to prevent overheating.Its output is rather unimpressive though and it’s a little on the large side for an AA or 14500 light. And I can’t help feeling the interface is unnecessarily complex. If Skilhunt could improve the output and perhaps use Anduril 2 firmware instead if they want a customisable torch, I think they could be onto a winner. Thrunite T1S There’s also the enthusiast’s favourite the Emisar D4V2 which you can configure however you like – front LEDs, switch LED, body colour etc. Turbo output from Emisar D4V2 (3 x domed Nichia 519A 4500K emitters 3800 lm) Below you can see the switch indicating in green. When the Sofirn SC18 flashlight is turned on, the switch will indicate the approximate battery level for around 5 seconds. Green means “good” and red means “poor” (or “low”). Flashing red means recharge immediately. But this torch is bigger and heavier at 78.2g – starting to approach the size of compact 18650 torches like this Olight Baton 3 Pro.

This is the default operation of the torch, but the TS10 runs Anduril 2, an open-source firmware for torches. Anduril is completely configurable but quite complex – I could fill an entire video covering all its options. You shouldn’t let that put you off, the default operation is pretty close to my perfect user interface anyway. But if you like fiddling, I’d highly suggest reading the manual that I’ll link to down below. If you get to grips with Anduril, you can have the same setup with every Anduril torch you own. This has been fine on my keys, but does weigh 10g less albeit with a fraction of the performance and no USB charging. I think you could still get away with this on your keyring in a pinch even though that’s not its intended purpose. Like the Fenix E18R V2.0 these modes are very well regulated and my measurements confirmed Olight’s specs with constant outputs up to the 300 lumen high mode. Turbo turned on at an impressive 1310 lumens, was still at 1299 lumens after 10 seconds, 1282 lumens at 30 seconds, and pretty much as spec’d dropped to 290 lumens after 90 seconds where it remained at 5 and 10 minutes and for as long as I measured its output. For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. Also, here’s the light with the worst PWM I could find. I’m adding multiple timescales, so it’ll be easier to compare to the test light. Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, which is 50 microseconds (50us). 10ms. 5ms. 2ms. 1ms. 0.5ms. 0.2ms. In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line. I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too. User Interface and Operation ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries. Peak beam intensity and beam distance measurementsAnother thing that’s a bit annoying is the jump between moonlight and low. The difference between low, medium, high, and turbo is ok, but not having anything between 1 and 90 (advertised) lumens is jarring. If you think accidentally activating a 10-lumen low mode when you’re expecting moonlight is bad, hitting low on the SC32 will leave you blinking for a minute afterward. It’s no better with the smooth ramping mode either, since it’s very hard to get into a level below the stepped low level. Lumen measurements (for each mode) Mode The Thrunite T1S comes in a plain box with a lanyard, spare o-rings and spare rubber flaps for the USB charging port, a USB-A to USB-C charging cable and a user manual. With the torch off pressing the mode button shows the battery level of the torch with a graphical icon and its voltage. It’s fully charged at 4.2V. const defaultIndex = !!defaultSelectedVariant ? data.images.findIndex(img => img.src == (defaultSelectedVariant.image && defaultSelectedVariant.image.src)) : -1;
