60 watts would be good. More won't really hurt most plants. This brand is a good brand, I use these primarily. I'd get the 24" 65W 6700K fixture. cd-16981 $59.99.

If you ever wanted to go with a white light get a 10,000K bulb. A light for $350 would probably be a some crazy markup, or a cheap POS metal halide, both of which would be crazy to put on a tank that small.
