George is correct so far as normal fluorescent, and of course, incandescent, lighting. These are not regulated for emissions in the US. But the new energy-saving RF lighting devices (bulbs) are regulated under FCC Part 18.
The limits appear to be quite generous. The regulations are found in 18.305 for radiated (above 30 MHz) and in 18.307 for conducted (including the AM/MW Broadcast band). I recall that the ARRL fought the relaxation of the emission limits because some lamps operate (if I tremember correctly) in the amateur 20 meter band or nearby (maybe 13.56 MHz ??). Jack Jacob Z.
