depending on the amount of light you're planning on needing for the tank, there are even better options for pretty cheap bright lights for a small tank. how heavily will it be planted? will you inject CO2? what kind of substrate and fertilizer are you planning on using, if any?
if you are planning a high-light tank, then home depot carries daylight compact fluorescent screw-ins that are 15w, 19w, and above. the beginner line kits that i've bought usually have a hood that can handle up to 20w bulbs (although most aquarium bulbs are lower than that). that being the case, if you get 2 x 19w bulbs, that's 38w of cf light in a 10g tank. pretty darn good. the best part is that they're not as expensive as two normal 15w daylight fluorescent tubes, and give you more light. I've seen the 15w daylight compact bulbs on sale for $5 a pair here at home depot. that's a steal.
if you plan well, your first tank can be a spectacular success whether low light no CO2, high light diy or pressure CO2, or med light with or without CO2. if you're planning on getting easy, low light plants, then lots of lights would be counterproductive, causing algae outbreaks on the leaves of the slower-growing low light plants (anubias, etc). on the other hand, too little light in a tank that's got fast growers, ferts, and CO2 can give you results that are just as ugly. IME, one side or the other is easier to master first, and then you can start experimenting with "medium" light levels in order to satisfy the needs of both low light and higher light demanding plants.
i write all this to encourage you to enjoy the brainstorming period before planting the tank so that you know exactly how to please the plants and the fish that will inhabit your tank. planning a new tank is my favorite part of the whole process... browse lots of photo galleries, look in aquarium books and magazines, pay attention to names and demands of the plants and fish you like, and if you can't find that information, by all means ask around (that's why this forum is here). once you make a plan, execute it.
in any case, i've rambled too long. best of luck!
