Lightbulb noise

lightbulb making rather high pitched buzzing sound when turned on. Pitch of the buzz gets modulated somehow, I didn't influence it in any way. It's how this lightbulb sounds by itself. You can also hear sounds from the street and from nearby apartments. Repeating thump also appears but I can't remember were I came from, possibly wasn't aware of it at the time of the recording. As the lightbulb was attached very high I had to keep my hand straight up for a few minutes, thus the handling nose. but I think it only adds to the recording, making nice rhythmic composition in addition to the buzz.
