This is some really Good Advice.

Wow-we can't trust man in anything anymore-
Professor John Marshall and others are concerned that the newer low-energy light bulbs may cause sunburn-like damage to your skin, premature aging, and even skin cancer.
Our rulers in Washington know better, of course. According to the Environmental Protection Agency (EPA), compact fluorescent lamps (CFLs) have earned their “Energy Star” rating as a product that protects the environment and climate through superior energy efficiency.
The light from an incandescent bulb comes from an electrically heated filament inside a glass globe filled with inert gas.
In contrast, low-energy bulbs use argon and mercury vapor in their spiral-shaped tube. The heated gas produces ultraviolet (UV) light rays, which stimulate a fluorescent coating inside the tube.
As this coating absorbs energy, it emits light. Professor Marshall said the concern is about some of the light rays these CFL bulbs emit.
Recent scientific evidence indicates these rays are damaging to human eyes and skin.

Researchers uncover the dark side of a bright idea-
The Stony Brook team, led by Miriam Rafailovich, PhD, Professor of Materials Science and Engineering and the Director of the Garcia Center for Polymers at Engineered Interfaces at Stony Brook, measured UV emissions from CFL bulbs as well as the phosphor coating, which is supposed to contain UV radiation and prevent it from traveling farther. Their study also compared the effects of both CFL light bulbs and the incandescent bulbs on human skin cells.
The light bulbs were randomly purchased at stores in the Stony Brook area. It appears that radiation leakage arises from cracks in the phosphor coating, which were found in ALL the light bulbs purchased and tested.
Yes, in each light bulb they found the phosphor was cracked and emitting radiation.

Bottomline: Further testing showed skin cells experienced significant damage when exposed to CFL light bulbs, but no damage at all when exposed to incandescent bulbs of the same intensity. “Our study revealed that the response of healthy skin cells to UV emitted from CFL bulbs is consistent with damage from ultraviolet radiation,” said Professor Rafailovich in a statement. “The results were that you could actually initiate cell death,” said another member of the Stony Brook team, Marcia Simon.
The group recommends that consumers exercise caution when using CFL bulbs. They offered one possible safety recommendation, namely, “to avoid using them at close distances and that they are safest when placed behind an additional glass cover.” This may be one way to protect your skin from the UV rays these bulbs emit. But there are additional health concerns associated with these energy-efficient bulbs as well…
