Imalent MR90 flashlight review
In the past year or so, Imalent have produced a whole range of high output flashlights, such as the MS08, RS50 and MS12 Mini. The Imalent MR90 is their latest powerful flashlight. What sets the MR90 apart from the others is the combination of high brightness (lumens) and beam distance (candela). This is due to…
Imalent MS08 flashlight review
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…

Cyansky K3-I8 infrared flashlight review
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…
Acebeam X50 flashlight review: brightest soda can flashlight in the world
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!

Astrolux WP2 LEP 2.3km throw flashlight review and beamshots
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.
Lumintop Thor II LEP Flashlight Review
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.
Wurkkos TS30 flashlight review
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…
Imalent RT90 flashlight review
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…
