Greg,
Home Depot and Lowes (and even Walmart and Kmart) have light fixtures with plastic covers built in (I think they are designed for under-cabinet use) that range in size from 18" to 48". You can use a regular plant bulb in these as they are single bulb design. Home Depot's brand is by GE and they call it an "aquarium/plant light". You dont need to buy the aquarium specific one as they regular unit is the same with a different bulb. You can buy a grow-light from the same place to use in place of the regular bulb.
Hope this helps.
Here is a link to the lowes item so you can see what the lights look like. In case the link doesnt work, try lowes.com and search the lighting section for this:
