Reflectivity

Back when I was an academic, we did some review of reflectivity. One of
the best bargains is simply white paint, which gets you 90-95%
reflectivity (or so, I'm doing this from memory). Mylar is better, with
something like 95-97% reflectivity, and the next step up is silverized
teflon which has 99%+ reflectivity, but costs some hundred dollars per
square yard. Aluminum foil is not particularly the best. Personally, I
paint the insides of all my fixtures white, and if I need more than that,
get mylar.
