First-generation compact fluorescent light bulbs were very noisy (hence me listening to the '98 World Cup by candlelight!) but LED bulbs are pretty quiet, as most of them use a simple capacitive ballast.

And it's not just energy-saving bulbs. There's even a mechanism by which filament bulbs can produce interference at VHF and SW!
