How far???

[Breeder]

I have a small question. How far does the light of a UVA-UVB fluorescent can be effective on the birds? If i have the fluorescent too close to the birds, will be any problem?

Yes, there can be an issue. Full Spectrum lights that are for birds (*NOT* reptiles) have a burn in period where-in they are strongest. If at the recommended distance, or closer, at this time, it can cause dry eyes, or more or less sun-burned eyes. After the burn in period, then it's fine to have the light at the recommended distance away from the cage and no closer.

NOTE ON LAMP BURN IN:
Compact fluorescent lamps have a "burn in" period when the light and UVB output is at its greatest. For your new AvianSun 5.0 Compact Fluorescent Lamp, this period lasts about two weeks when the lamp is used to provide a normal photoperiod or day/night cycle at 10 to 12 hours per day (150 hours of use). -----

----- WARNING: DO NOT place lamp closer to your bird than the recommended distances listed above as eye damage may occur.

My light is a normal fluorescent UVB-UVA light. Do i have to use those distances as well? 30-50 cm?

Do you know what the specs are on the light?

It's recommened to usually keep the lights at least a foot away from the cage, although I know some people who have lights right above the cage without issues. It might depend on the brand of the light, or perhaps in what area the bird spends the most time within the cage.

The manufacturer will usually recommend either a one foot or two foot throw - closer than that can cause retinal damage.
