It's too bad you are going 20l. I was looking around and found this on clearance at premiumaquatics and it includes the bulbs. You could always use your 20L as a sump and go with a 36" tank. Someone here had a nice 60 high for sale with stand. See now I'm just being an enabler.

I was tempted to buy it since it's the last one and sell my lights off, just don't want to go back to those elect bills.
