refugium lighting

[BT05]

Buy a clamp lamp from home depot (comes with a cone reflector) and buy a compact fluorescent bulb from a hydropnics store. Pick the wattage depending on the water level in your refugium/sump, just make sure its an R30 base. These types of bulb are typically 6500K but there are 25000K ones too if you want to set up 2 lamps to get more blue in the spectrum. If your refugium is not viewable and you are only interested in growing things, then the cooler bulb will do.
