Just recently, I translated an article on compact fluorescent lamps
and their EMF emissions by Wolfgang Maes, the initiator of the
Building Biology Standard. Take a look at the many oscilloscope graphs
and spectrum analyses. The huge harmonic distortions and high flicker
percentages speak for themselves.
The German branch of the Friends of the Earth (BUND), one of the
largest environmental organizations in Germany, issued a background
paper on compact fluorescent lamps in 2009 when the incandescent lamp
was banned in Europe. The BUND demands that lighting should be safe
both for the environment as well as human health.
Their recommendations for exposure limits apply not only to compact
fluorescent lamps but all lamp types. Any lamp that cannot meet the
TCO limit (VLF: 1 V/m and ELF: 10 V/m at 30 cm) should be taken from
the market. And by 2015 lamps should stay below the target threshold
of 0.2 V/m in the VLF range. For lamps used close to the body, the
BUND suggests a precautionary value of 0.02 V/m. I fully support these
Just for the record, Health Canada released data on EMF emissions of
CFLs this year. The details on the testing procedures have not been
released yet. But for the kHz range (VLF), the worst-case CFL is given
with 126 V/m at 20 cm. This is only 45% of the Safety Code 6 exposure
limit of 280 V/m, but it is 45% above the ICNIRP exposure limit of 87
V/m. Converting the measurements to a 30-cm distance, the CFL emission
level is 56 times higher than the TCO limit of 1 V/m recommended by
the Swedish standard on low-emission computer monitors.
