Update:

I found some small trailer marker lights at Northern Tool for about 2
bux. I bought one to cut apart for the lens. The Luxeons I bought
are Lambertian emitters. Their radiation pattern is more like a
small filament bulb than a conventional LED. I therefore thought
perhaps a lens devised for use with a small filament bulb might work
well.

It does.

The red Luxeon behind that lens is noticable even in direct sunlight.

I tried it tonight with two 60-watt patio lights and two 100-watt PAR
floods illuminating the backyard to provide some competition like
citylight in Brooklyn will provide. I walked back 100 feet to check
it out from there.

Uh...wow. I think this dog will hunt.
