Trumpy, there must be some decent ones about in the US surely. The UK is normally terrible for this sort of thing, but I recently picked up a rachargeable Battery Lantern that has 15 Million Candle Power. It uses a hybrid Xenon discharge lamp and a variable Fresnel lens so you can get a tight beam.
I'll see if I can find some info on the web about it, I'm sure it is American in manufacture. I found out about it doing some work for the RNLI, they use them on their Rescue Boats.
I have shone the beam across the fields behind my cottage, and the beam is visible all the way to the next house..about 2.5 miles away..with the naked eye. Even High level clouds...10,000ft plus glow if it is shone skyward at night.
