that is fine for now.. i have about 8 26watt on about 3-4 seedlings.. after 2 weeks you may want to double the lighting and consider HPS/MH bulbs..
just watch the temp anything over 80 is getting into hot grounds.
keep cfls about 4-5 inches from seedlings until first week, then you can drop them to about 2-3 inches once they have a few more leaves. also put a light fan/breeze to blow on them.. it helps keep them cool and also makes their stem stronger.
