OT: a strange thunderstorm yesterday in H-town. Lightning mostly at a very sharp angle, instead of usual where most lightning is typically close to the right angle.
Lost power for a while, but then some strange electrical event occurred.
Some bulbs, especially those that are 'new' (economical) type started glowing in red (not white or yellow) and several electrical outlets (I assume those with fuses) started a slight buzz (which I recorded) for a good 15-20 min, then stopped.

I am not an electrician, but what could have caused it? Some residual charge in the air? It was very weird, never seen/heard anything like that.
