You can usually bring the bulb back to the store as a return if it was purchased recently. The crappy part is that they will probably throw it out even if it's unused but that's policy. You should be able to get your money back. As another poster said, they will either bother the dragon's eyes or work out just fine. My store only sells Reptiglo and I always mention the Reptisun but say the Reptiglo is okay as long as you keep an eye on your dragon's eyes.
