I was an early adopter of Surefire, so early they were marked "Laser Products" I rode the Surefire train for many years. They were the premier light on the market, best machining, best warranty, best output, the Cadillac of lights no doubt.
Then they went to sleep at the wheel, refusing to adopt rechargeables, refusing to use cutting edge LED technology, resting on their laurels, and doing so at a price point way beyond lights with better output and comparable machining/finish. Years late, they started building lights compatible with 18650, the most cost effective and prolific battery type on the market, and did so still at a price point incompatible with reason. Were it not for taxpayer funded sales Surefire would have failed a decade ago..
I'm a China hater, they are not our friends, they steal our technology when they are not extorting it, they bribe our politicians and spy on us with reckless abandon. I avoid their products largely and refuse to eat anything sourced there.
That said, if there is a segment of the market that China leads in technology it is hand held lights. "Made in China" is not an indicator that quality is good and technology is cutting edge, quite not, but there ARE many Chinese light manufacturers who produce very nicely machined and finished, lights using the very cutting edge of LED's, and do so at a ridiculously low price. Regardless the brand of light you buy the LED is sourced in China. Hand held incandescent are dead. The overwhelming majority of driver boards are sourced in China, and the CNC machine that spun the tube/head/reflector will be found in Wang Dang Hot Dam China about 99% of the time.
Those Streamlight people are recommending? China.
Surefire LED? China.
So with that in mind, when I am sourcing hand held lights, I look the Chinese products first.
Best value on the market? Chinese lights.
