CFL's operate at high frequency using an electronic switching ballast to chop up the 120 volts -- that's how they are able to use less energy when compared to an old-style incandescent bulb. A typical operating frequency for an electronic ballast would be in the region of 20kHz to 100kHz, a frequency range known to produce adverse effects on one's health.

Written by a scientific illiterate, it should be needless to say.

1. Electronic ballasts are not the reason that compact fluorescents use less energy than incandescents; even ordinary magnetic ballasted fluorescents accomplish that. Electronic ballasts make it possible to reduce the size and power consumption of CFLs compared to mag-ballast fluorescents.

2. 20KHz - 100KHz "known to produce adverse effects on one's health?" Show me a study that didn't originate with envirokooks, please.

‘Rasmus, your point number 1 was beautifully written - a very concise and clear practical explanation. I’m too long winded to do better. Thank you.
