CFL = Cancer Florescent Bulbs?

Some scientists say they're dangerous even if they're not broken:

Their report advises that the bulbs should not be left on for extended periods, particularly near someone’s head, as they emit poisonous materials when switched on.

Peter Braun, who carried out the tests at the Berlin's Alab Laboratory, said: “For such carcinogenic substances it is important they are kept as far away as possible from the human environment.”

The bulbs are already widely used in the UK following EU direction to phase out traditional incandescent lighting by the end of this year.

But the German scientists claimed that several carcinogenic chemicals and toxins were released when the environmentally-friendly compact fluorescent lamps (CFLs) were switched on, including phenol, naphthalene and styrene.

Andreas Kirchner, of the Federation of German Engineers, said: “Electrical smog develops around these lamps.

“I, therefore, use them only very economically. They should not be used in unventilated areas and definitely not in the proximity of the head.”

Sounds like the law of unintended consequences strikes again.
