Use of compact fluorescent light (CFL) bulbs have gained popularity as energy efficient and provider of good amount of light in comparison to the conventional incandescent light bulbs.
These are a little costly than the incandescent bulbs, but in the long run saves the cost of energy in many fold and lasts longer.
Now, researchers at Stony Brook University have found that CFL bulbs may leak UV rays that can be harmful to skin. They concluded that the CFL bulbs have cracks or bald spots in their phosphor coating, which appeared to allow both ultraviolet rays (UVA and UVC) to be emitted.
They also say that the response of healthy skin cells to UV emitted from CFL bulbs is consistent with damage from ultraviolet radiation. Traditional incandescent lights bulbs tested the same way had no effect on skin.
The researchers stress that consumers should avoid using compact fluorescent light bulbs at close distances.

An experiment has shown that strawberry extract added to skin cell cultures acts as a protector against ultraviolet radiation as well as increasing its viability and reducing damage to DNA. Developed by a team of Italian and Spanish researchers, the study opens the door to the creation of photoprotective cream made from strawberries.
