That is the information that I gave you as those were the bulbs that I thought you were referring to. They must have a CRI of 94+, a K Temp of between 5000and 5500 and a UV rating of 2. Any other Specifications than these and the bulb can blind your bird or it can burn him to death, It is a nasty way to die and quite painful as it is the same as dying from sunburn only you don't live long enough to get out of the sun, so the sunburn keeps getting worse and deeper.
Because of the dangers of these bulbs I don't use them to convert the precursor into vitamin D-3, there are safer ways of getting them this vitamin. I do use the bulb for the purpose of providing the parrot with the proper lighting to see by. Parrots see into the ultraviolet spectrum, which is invisible to us, and because of this ability they see far more colors than we do and next to what they see with the proper lighting we are color blind in comparison. It would be like either seeing the world like the old black and white TV's or seeing the world through the hi definition color TV's of today, or something very similar.
When using the full spectrum lights for vision enhancement like I do the bulb is never closer than 3 feet from the bird. To use it for converting the vitamin d-3 precursor into vitamin d-3, the bulb must be about 12 inches from the bird. To me the risks involved in using the bulb in this manner are just too great, and there are in most cases some other much safer ways of accomplishing this.
