Finally a good 'side switch' light – Romisen RC-R4 Cree P4 LED Flashlight Silver (3V~8V Input) Reviews

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

Pros:
Great to finally have a nice side-switch flashlight. It's compact and fairly light-weight for an alluminum body. Bright output with focused hot spot for throw. Have very level output through the battery life due to a good regualted driver circuit. Nice finish. Tail stands. Good knurling for grip. Appealing design.
Cons:
Tint was very slightly greenish, but not noticable unless doing some side-by-side comparisons. 18650 batteries don't fit.
Other:
Mine had a defective switch that was fairly easy to fix (which appears to be sku 5588). I would have liked to also use 18650 batteries since the driver circuit accepts a single Li-ion voltage range...but they won't fit in the body. Maybe 17650 will fit...but it will be close. Due to the good regulation, you can't tell that the batteries are about to run out, so protected 16340s will suddenly trip the PCB...then darkness (fairly common with this setup).
Bottomline:
Well worth the money for an easy-to-use side switch light.
