Oops, I was measuring the beam as if it were a square, not a circle.
(square or circle won't change the answer by an order of magnitude)
No doubt the police will end up buying these things at US$ 10,000 a piece, when you can basically make the same thing by popping a defocusing cap on a 50 dollar dx 100mw. I carry around a 100mw greenie with a WL defocus cap. Gives a nice head-sized spot. You never know when it might come in useful .......
