lighting for my fuge

[tlk]

I am slowly leaning towards setting up a refugium/sump where I can keep all my stuff (heaters, skimmer, filter, etc). How much light do i really need to keep the culpera (sp) and 2-3 pieces of lr happy?

You don't need a lot of light for a fuge. The more light, the more growth though. I have two NO 20w bulbs on my 40g fuge and it's working out ok.
