The Nitecore MH12 Pro is a relatively slim light that can put a lot of light downrange for a few seconds, but that performance comes at a cost. If you're a first responder, this light may be for you, especially if you're on call out of uniform.

Some tools do their jobs so well they're a little boring to write about. The E75 provides everything most of us could want in a midsize flashlight, and very little we wouldn't.

The Wuben B2 is a well-priced, efficient bike light powered by a 21700 battery and equipped with USB-C charging. It has a lot of offer, but it won't be for everyone

Few flashlights are also good USB powerbanks. Even fewer good USB powerbanks are also good flashlights. This floody, somewhat pocketable model manages both, with a side of mulitcolored aux LEDs.

The Acebeam E70/FC40 is a can of sunlight. This versatile 1x21700 light fits comfortably in a jacket pocket, uncomfortably in a pants pocket, and makes some of the most natural-looking light I've seen from a flashlight.

The Thrunite T2 is a 1x21700 flooder with the highest efficiency I've ever tested in a flashlight. It features USB-C charging, and can be put in a pants pocket in a pinch.

The Nitecore MH10 v2 is a general-use flashlight powered by a 21700 Li-ion rechargeable battery, with onboard USB charging, and the ability to use a great many different sizes of Li-ion cells.

The Xtar ST2 is a USB-C PD fast charger for larger cylindrical Li-ion cells. It can charge two cells at up to 4A and has indidivual temperature sensors to prevent overheating. Its performance is impressive, but mine proved unreliable.

Acebeam says the L30 is "like a side-arm that takes shotgun shells". That's been done and isn't a great idea, but the L30 is. The high-only tailswitch with all other functions on the side switch is what I would consider an optimal UI for a duty type light. Output is around 4000 lumens until heat limits it to 2000.
