    Comments about Philips Lighting Company 25 Watt, 36 Inch T8 Bright White Fluorescent Bulb:

    I bought these bulbs for my birds. They are indoors almost all year round, so they never get the good sunlight that they need for good health. I got these to help replace what they do not have access to. I would recommend these to any bird owner. They need UV light to stay healthy, but it must be full spectrum fluorescence. Excellent product, long life, good quality, have had no problems so far. Also, easy to set up.
