does this light look good? Would you buy it? http://cgi.ebay.co.uk/11W-MARINE-WHITE- ... 240%3A1318 I like the arcadia arc pod lights, but they're expensive. My only issue with the above light, is I don't know if I can get replacement tubes for it. I was going to get two of them - equaling 22watts. The tank is 12*8*8.
