Some pet stores will carry a T8 ReptiSun 10.0 tube and a slimline reflective fixture for it. I haven't seen the higher output T5s in a store. I also haven't seen the MegaRay bulbs in stores. You may have to search around a bit. If you're concerned with security of online shopping, you could use Paypal which is fairly secure, or you could purchase an American Express or Visa gift card that can be used like a pre-paid credit card for online purchases. The T8 fixtures should be mounted inside the tank about 6-8'' above the basking spot with no plastic covering or mesh between the bulb and the basking spot (those intercept UVB). The T5 tube and the MegaRay MVB can be mounted above the tank at around 12-18'' above the basking spot as they are quite a bit more powerful.
