Does anyone know when this is - I've been stocking up - but probably need more.
The danger of compact fluorescent lighting
Snips: I know I’m not the only one. I’ve talked to others who have similar problems and there have been some reports about CFLs increasing migrants, depression, and worsening symptoms in diseases such as Lupus. Traditionally healers, such as Barbara Ann Brennan, have long advised to never do healing work under fluorescence lighting of any kind to avoid making yourself ill. These lights drain our energy and especially for us in a healing profession this can be very dangerous.
Studies have also show that children do much better under normal lighting. From Earthwatch - Compact Fluorescents vs. Full Spectrum Bulbs
As Dr. Havas states - Compact fluorescent lights (CFL) produce radio wave frequencies. These frequencies radiate directly from the bulbs and go on the electrical wiring in the home or school causing poor power quality or dirty electricity. The closer you sit to the bulb the greater your exposure. Because the high frequencies travel along the wire you can be exposed in other rooms of your home as well as the room that contains the CFL.
Also new research has come to light that indicates that CFLs emit a high humming sound that is not in our range of hearing but is in the range of hearing of cats and dogs. Can you image hearing a high pitched humming sound all day long. It would be enough to drive you nuts! Many pet owners report that their cats or dogs do not want to be in rooms with CFL bulbs on and will become anxious if they are forced to be.
