Making a reflector- what materials to use?

Currently I have one 6 socket vanity light setup with some y adapters hanging in my grow area. I'm going to attach two of these vanity lights to some pvc to keep them in place and to add extra lighting.

I have noticed in pictures that the guys with reflectors are getting more direct lighting. What can I use to make a reflector? I still have some panda film left over that I could use. I wasn't sure if wrapping some cardboard in the panda film would be safe.

Hmm...how about chicken wire bent in a U shape lined with panda film? The chicken wire is easy to work with and light weight...

If cost is an issue you might try aluminum foil, but the best reflector would be mylar. (2 or 3 Mil thick) go on Ebay and search for it, (Hydroponics + Mylar)

^^^^ That is horrible advice! Do not use aluminum foil it will cook your plants, hot spots and not.

I already have panda film and also have a left over emergency blanket. I just wasn't sure if I can safely make a backing out of cardboard and then just cover it.
I know I could use sheet metal, but I was looking for something else to use.
