Quite honestly, the most common solution is 2x4 and plywood.
I take a 12" or so square of 3/4 ply and cut a 4" round hole in the middle. Then, I glue a piece of 1/4" ply to the top of that (same dimensions), with a 1/2" hole in the middle. If done right, you'll end up with a nice 12" square that looks like one piece. Paint it black and bolt your fixture to it. I can probably make 50 of these for less than 50 bucks.
I have a few old mic stand bases kicking around - but not enough. I need an economical solution to use a single yolk LED as an uplight. x 16. What inventive ways have you all come up with?

In a similar fashion, a large tradeshow booth required uplighting behind frosted plexiglass. While walking down the hall at the hotel, a few 'room service' plate covers joined us for the show. Stainless steel construction with pre-existing hole in the top. Viola- Instant PAR base! These were returned to the hotel at the end of the tradeshow, of course.
