the answer is YES. You can use thoes lights. The ballast is attached to the bulb. I use a couple of 25 watt ones on my tank. Make sure you buy the ones that come in the right light spectrum spectrum. I think mine are 6500k, but you can get ones that go up to 10,000k.
Buy a couple of desk lamps, and you'll have pleanty of cheap lighting. You dont have to buy the bulbs online either. Almost any hardware or home improvment store will carry the same product. There are meny diffrent brands.
