I saw a youtube video where a guy made a ghetto reflector out of aluminum heating duct. You know that 3" or 4" diameter heating pipe thats connected to your hot water heater? Most of that is galvanized steel for code purposes. But they make that same pipe out of aluminum and it's used for bathroom exhaust fans and dryer vents.
Anyway, he bought a piece of that aluminum pipe and used it for a reflector. It's pretty shiny already, but I'll bet you could go to the auto parts store and get some aluminum polish. Couple minutes with a drill, a felt buffing wheel, and some of that polishing compound - you'd have a mirror finish reflector.
You can also buy polished aluminum reflector material from Catalina Aquarium. I use this stuff for my fish tank lights. It's relatively cheap (not as cheap as the pipe) and works great. You just roll it into an arc and slap a few screws or whatever into it. Mount the light and you're shining like the friggin' sun!!
He lists sizes by width. I'm pretty sure the standard length is 12". So his 12" piece is going to be 12" x 12" His name is Jim. I don't know him personally or rep his products. I'm just a happy customer. Been buying my fish tank lights from him for about 5 years.
He has a link on the left hand menu for hydroponics stuff. But here's the reflector material if you're interested.
