I had found 4 umbrellas on ebay for $30 total with shipping two 36" white, and two 42" silver. wasn't woo bad of a price I thought, but then the whole specific connection adn whait if I want to mount the lights in the ceiling and all that. Ended up not getting them. I know i'm gonna have to finish boxing in the roof, also will have to put up sheet rock on one wall and paint that, probbaly white or black, not sure yet. And check some more into the lights. I will have to check on the cool lights. And thankfully, my shed has no windows in it. Maybe the cheapo dishpan lights will work with the right bulbs. the lights i'm talking about are relatively cheap, and have a clippy spring grip arm on them to attatch them to say the rafters in the ceiling and it looks like a giant aluminum dish pan or bowl. softboxes or reflectors, I may be able to make out of clotheshangers and duct tape.
