Get yourself a Circline screw-in circular fluorescent tube - the type where you take out the incandescent bulb and replace it with a circular fluorescent. They sell these in 23W and in 28w. The 28w ones are more difficult to find but you can just take the circular tube off and replace it with a 27W daylight CF bulb. These are the flat 4 tube replacement bulbs. The connector on the Circline will fit into the CF bulb (it is a Square pattern) with no cutting or soldering. Should cost you less that $25 for everything and you will get more light directed at the refugium than the spiral bulbs.
If you're not sure what you are looking for, I'll try to dig up some links on Home Depot's site.
