Energy Saving

Why energy saving bulbs flash even when turned off?

Sometimes our energy saving bulbs of lightning every few seconds, even while the computer is off. When I asked our electrician about this, said it is quite common and does not indicate a defect wiring, such as defective insulation. But he could not offer an explanation. What's happening? Yes, Bill Russell, I'm sure. Martin H response is interesting. Fluorescent tubes contain a gas discharge tube. Microwaves and RF radiation can light of these, so maybe a magnetic or electric field rapidly changing is the cause. But there was no storm activity over time, and I noticed that on many occasions.

Not sure, but I would like hypothesis that, since they are fluorescent bulbs that can trigger magnetic fields. I've attached a link to a photo of someone stuck a handful of light bulbs light pipe length in the ground under power lines. The field generated by power lines really light bulbs (looks very cool). If your thing is perhaps flickering lightning?
