Sofirn SC18 Torches LED Super Bright Rechargeable Torch Flashlight 1800 Lumens IPX8 Waterproof, EDC Light with Side Switch 6 Modes,USB Hand Torch for Camping, Hiking and Emergency Use

Product Information

And the magnetic tail cap, mostly intended for snapping to the charger, is also just about strong enough to hold the torch in any orientation for hands free operation. The Wurkkos WK03 is a low-cost 18650-based flashlight that offers USB-C charging and a nice range of output! It makes a great gift! Despite the exaggerated outputs this is a great little torch with bright high CRI LEDs, good build quality and all the flexibility of its Anduril 2 firmware. Fenix E18R V2.0 Sofirn didn’t go for “short” on the SC21 Pro and used a nice deep reflector. This gives a great beam profile.

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. I measured 4180K for the LEDs with a pretty neutral tint and a very high 95 CRI. They’re behind a TIR or Total Internal Reflection lens and I measured a throw of 104m with a beam intensity of 2700 candela. It’s less than what’s quoted in the manual but still a useful throw for a small torch like this. Again if you’re unfamiliar with any of these terms, I explain them in detail in my previous video.

Here’s a sort of generica user interface table for Andúril 1 anyway! Every feature mentioned here might not apply to the Sofirn SC21 Pro flashlight. State Unfortunately, it is important to note that the Sofirn SC32 underperforms by about 25% all around. In reality, the visual difference between 1500 and 2000 lumens is hard to discern, but what’s advertised and how it actually does are different things. 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)

My first article and video in this series covered even smaller keychain torches. And also introduced a few technical terms – so it’s worth a read / watch if anything I cover in this video needs further explanation. I measured 1240 lumens in turbo but that dropped to just over 1000 lumens in 10 seconds and 250 lumens at 30 seconds – far lower than spec’d. At 5 minutes it was at 138 lumens and at 10 minutes it was 102 lumens which it held for a couple of hours. That output when you turn it on is still pretty bright for a tiny torch even if it is just for a short time. And you can even increase the step down temperatures in Anduril which can increase runtimes slightly in the higher modes. I’ll discuss this briefly later. Also if you’re using these torches outside in cooler temperatures, you’ll also get better runtimes in the brighter modes. Probably the most impressive feature of this torch for its size is its beam profile. It has 250 metres of throw or 15530 candela of intensity. But even with the tight hotspot from that deep smooth reflector, there’s still enough spill for it to be useful as an EDC torch. Chế độ Vừa: 350 lumen. Sáng ổn định, thay đổi nhẹ khó nhận ra trong suốt thời gian sáng đến khi tắt.

Yes, this is documented in the manual, and if I had sat down and read the whole thing before taking the light out of the box, I would’ve expected that, but this is not intuitive. Sure, there are other lights where turbo is part of the main group or you have to hold for off, but not being able to turn the light off directly from turbo is very unusual. The joys of knowing how to reflow an emitter. I’ve only just started doing it and it’s such a great thing to learn. Sofirn sent 2x IF19’s and one SFT40 to reflow in. They released with an SST40 and currently the SFT40 is in production. This switch also has indicating features – below it’s seen indicating red for low voltage. Notably, the switch will indicate for 5 seconds after the light is turned on, as follows: Here’s where things get a little interesting. Under the crenulated bezel, the SC32 uses a fresnel lens not commonly seen on flashlights. In a nutshell, the fresnel lens does the job of a convex lens by dividing up the curvature of the lens over a number of lower-profile concentric rings. This allows the lens to be flatter, saving space and material. Since this fresnel lens is shorter than standard TIR lenses or reflectors, it helps keep the light short. There’s no glass lens to cover the plastic fresnel lens, so that may shorten the overall length as well, but then the plastic lens is exposed, so keep that in mind.
