Flashlight quick reference, technical explanations and guides. If you have something about flashlights you want answered then let me know.
The Luminus SBT90.2 is a second generation of the SBT90 LED and can output over 6000 lumens with a focused beam, great for long distance throw.
How would you like to see literally miles away in the dark? Some of these lights have a beam that throws so far that you need binoculars to make the most of them. There’s been a few new massive flashlights recently. Here’s a quick run down.

This week I took an original 1980s Playskool plastic flashlight, removed the insides and replaced them with a 4000 lumen flashlight.
Flashlights with the Anduril UI step down the brightness when they get to hot. They do this with a temperature sensor, which may need configuring when you first get it.
Abbreviated history of high power single cell flashlights
A user interface is the way that someone interacts with a device. In the case of flashlights, it’s normally by 1 or more switches that are pressed. A UI can be the different between a flashlight staying on a shelf or being used regularly.
You may have noticed that this blog seems to focus on flashlights (or “torches” in the UK). They’re simple things compared to most technology but their elemental nature makes them almost entrancing.
I started looking for the best pocketable flashlight that throws its beam a long way. This article documents the rabbit hole I ended up in. In it I’ve compared lights from EagTac, Lumintop, Acebeam and Emisar.
Multiply the candela by 4, then square root it to get the throw in meters.
Or square the throw in meters then divide by 4 to get the candela.

Imalent is well known for their incredibly bright flashlights, such as the Imalent MS18, which is the brightest flashlight in the world. Imalent features heavily on my list of the best high power flashlights so it’s no surprise that they’ve just released another. At 34,000 lumens Imalent MS08 is the brightest flashlight they’ve produced that …

This is something a bit different: an infrared (IR) flashlight from Cyansky. The K3-I8 is very similar to their K3 tactical light but with a high power IR emitter instead of a normal white LED. Note that the model name is with the letter I, not number 1: K3-I8, not K3-18. You can buy the …
Forty thousand lumens!!! No, it’s not false claims like the 990,000 lumen zoomies you see on sites like Wish. This is the Acebeam X50 that makes use of no less than 8 CREE XHP70.2 LEDs. It’s just so bright!

The Astrolux WP2 is a LEP flashlight that throws 2.3km or 1.3 miles. The only light I have that throws further than this is the massive Astrolux MF04, so I was interested to see how the much smaller WP2 would perform.
Pocketable and affordable 1800m throw LEP flashlight. My first LEP flashlight! What’s that you might be wondering? LEP stands for Laser Excited Phosphor, sometimes known as a White Laser.
Introduction Wurkkos are still new in the flashlight world but are starting to get fairly well known due to getting lots of things just right. Members of r/flashlight regularly recommend the Wurkkos FC11 due to its tint, build quality and USB-C charging. From what I understand they’re a separate company to Sofirn but the 2 …
1308m throw, 4800 lumens Introduction Imalent are known for their high power and long range flashlights, squeezing in as many lumens and candela as they can. The Imalent RT90 is one of these, designed primarily for high throw, rather than lumens. That said, it still produces almost 5000lm. Imalent released their RT90 flashlight at the …
This review was originally written for and appeared on 1lumen. This flashlight was sent to me for review at no cost by Convoy. I have not been paid to review, nor have I been holding back on problems or defects. Introduction Convoy is well known amongst flashlight enthusiasts. Especially for their low cost and easy …
Here’s another light from Sofirn. This time their SP31UV (or SP31 UV). This is their SP31 light with an ultra violet LED. About the light You may have already seen Sofirn’s white LED SP31 flashlight. It’s a dual switch flashlight with an 18650 cell and a CREE XP-L HI LED. Sofirn have reused the host …
I have an unusual flashlight review today. This is a versatile light that has both white and UV LEDs and you can twist the head to point sideways. About the light This light is sold as the EverBrite 90° Twist UV. It looks suspiciously like the Nicron N72, so I expect they come from the …

The Wurkkos HD20 flashlight is a right angle headlamp with a 21700 cell and 2 LEDs. About the light This is a big flashlight that you can also use as a headlamp. It has lots of bells and whistles and comes at a budget price. The HD20 has 2 LEDs that can be on individually …
The C8F is a high power tactical light from Sofirn. It has 2 switches for easy operation and throws a reasonable distance.
Another light from Sofirn I’m reviewing is the IF25A. This is a pocketable flashlight with 4 LEDs. About the light The IF25A is small but powerful budget light. It takes a 21700 cell and has 4 SST20 LEDs, pumping out up to 3800 lumens. It has an E-switch and uses the Anduril flashlight user interface. …

Read on to see what it’s like in real life. Purchasing You can buy the light from ImalentStore.com. It’s currently $129.95. Quick review This …
The Sofrin SP40 is a great entry level headlamp that has the quality of lights twice its price. It’s a great all rounder, coming with USB charging, an included cell, head strap and even an extra body tube for shorter cells.
Sofirn have produced a great budget light in the SC31b. The simple user interface, USB charging, included cell and pocket clip make this a great flashlight for all and easy to recommend to others.
The Manker MC12 is a pocket thrower flashlight that reaches 650m. This is a great light if you want to light things up a long way away but also want something that’s not so heavy that it always gets left at home.
Here’s a quick preview of the Manker MC12 flashlight, with 650m throw, exploring an abandoned WW2 building. You can read the full Manker MC12 review here.
The Nightwatch NS53A is a single 21700 cell hot rod flashlight that puts out 9900lm. This is one of the brightest lights for its size and is ridiculous.
