I need a reflector

Right now I built my own reflector out of cardboard and foil. I have a 400W metal halide and it is just dangeling and I know I am losing a lot of lighting going directly to my plants. Does anyone know how to build a reflector that can support the light and bring it in a horizantal direction?

no foil or cardboard. fire fire fire fire!!!!

i have some used cool tubes i might be willing to part with; pm me if you're interested.
