Suggestions for lighting a 5 gallon

What about a little gooseneck light? Azoo makes one that I've seen for around $15. I did a few Google searches and couldn't find the one I was thinking of, but here's a link to a similar one:

Either of those would work well, and another option is Walmart. They sell a desk lamp that uses a fluorescent bulb, looks like 4 mini bulbs, but it's actually a 4 pin 27W single bulb if I recall correctly, and I think it runs just a hair over 40 bucks. I tried some clip on lamps once, intending to use a 26W CFL but discovered after getting it home that the shade/reflector is too short and about an inch and a half of the bulb stuck outside the dome, which was just ugly and made it hard to look at the tank. Super cheap way to go ($7), but if you try it just make sure get one with a deep dome.

How about an Arcadia? I think the smalest size is 12" and I use one. It's really good.
