Yes, the bulbs are standard CF
bulbs. They only plug in on one end, so the length doesn't matter. As long as the bulb is matched with the ballast, like 55W, 65W, or 96W, you are fine. They come with Odessea bulbs, but you can use any others, like Coralife, etc. All the same bulbs. I have 3 of the 260W 48" CF
fixtures (4 65W bulbs each) and like them alot. the only problem, like mentioned, is a little noisier, but that can be DIY's to quiet it down some.
