And for those wondering, these are the lights:
Liroyal E27 4w 5v High-power Day White Light Bulb - - Amazon.com
The only problem is that they come on a slow boat from China. It could take a while before they get to you. I ordered two batches of four. The first batch came in about 3 weeks, but the second batch took 6 weeks. Two of the eight bulbs have died, but for the price, I'm ok with that.
I made a junction box that hangs in one corner of the screen room to connect the lights to. And you need RCA phono plug extension cables and splitters to distribute the power to all the bulbs. I'm an electronics engineer so I'm comfortable with fabricating the junction box and interconnecting cables where needed. You will have to figure out how to connect it all up based on your own level of expertise.
