I own several Streamlights so I have first hand experience with those. I must say, the SL TL, NF, and Scorpion LED series lights are great in performance, machining and mfr'ing quality, and value.
I had a couple of Pelicans, what was great, no probs, the other had a bad switch that worked about 5% of the time. I've seen other Pelicans tho and they seem quite good.
I've never owned an Inova, but played with a few and they seem very nice, great machining, and seem solid.
Then there's all the low volume and custom lights, but for high-volume mfr's, the above are my favorite US brands.
Keep in mind tho that if it has any electronic circuitry, it's not an all USA light.
