Review: Fenix TK25 R&B, an 18650 flashlight with high-output red and blue secondary emitters

The TK25 R&B is an unconventional design with a rotating head to switch between two white, and one each red and blue emitters. It offers very high red and blue output, but no low-output modes to preserve dark adaptation. It's intended for hunting animals that don't react to red light, and following blood trails with blue. It should work well for that application, though better color quality for the white emitters would be most welcome.

Review: Armytek Prime C2 Pro XHP35, a versatile 18650 EDC light

Review: Klarus G30, a 3x18650 workhorse

The Klarus G30 is a light for extended use. Its 900 lumen mode lasts 3.5 hours with no change in brightness over time. It's predictable, reliable, and better for getting work done than showing off.
