I don't have MH lights, but i built my own lighting "hood" for flourescents with a white vinyl gutter with end caps- don't laugh- if you looked at it, you would not know that it was homemade unless i told you (most people are amazed when i tell them).
Anyway- i was trying to find out what to do for reflection, and a friend of mine who does heating and air conditioning gave me some tape that he uses for heating and cooling systems-- it is shiny like aluminum foil, and it reflects the light great. the best thing, is that it is desinged to hold heat IN and you wrap it around pipes that are hot- so the hotter it gets, the better it actually sticks-- so you don't have to worry about the heat making it fall off. the stuff i got does have the brandname on it in little red logos, so it is not 100% reflective, but if you really wanted to you could but pieces out to cover all that....
i can look if you want when go home for lunch and post the brandname so it is easier to find.
worked great for me.... oh- i am using NO bulbs, but it would work with VHO as well....
