Refugium Lighting

[Scales]

I have just finished sectioning the sump on my latest tank and need to turn my attention to lighting. Anyone want to share their (hopefully low cost) refugium lighting secrets? Since the fabled Home Depot LOA (PC) fixture is not available in B.C. (or at least I have not found it), what are people using to light their refugiums? Has anyone experimented with the other "hardware store" fixtures like the (quartz?) halogen floodlights? Your collective experience is appreciated....before I open my wallet....again....and again....and again....
