Query: A Must Have for the Parrot Owner

I have been using the featherbrite light bulb for 3 years now. Every year I purchase a new one so that my parrots will receive all the benefits of full spectrum lighting.I like the the featherbrite bulb becuase it doesn't generate a lot of heat. I have the lightbulb in a clamp light which I keep on the cage. I even use a timer.Since I have been using this type of lighting my parrots have been looking healthier, their feathers are shinier and they seem happier. I swear by full spectrum lighting.
