Thank you, Verilux! I love the new Happy Light and so do my cats. It's wintertime, with less daylight, and these guys live indoors. They are attracted to the light, and sit in front of it while I have it on. Full spectrum lights were recommended to me about 40 years ago by an elderly woman who was exploring alternative therapies with her doctors. I've had a Verilux Happy light for many years, and enjoy it. Happiest Holidays!
