    Energy saving lamps: Ive finally figured out how they work. Simple really.

    You too may have noticed the delay in illuminating when switched on - well
    this is the key, they actually slow down the electricity hence they use
    less of it.

    Clever stuff eh?

    That's not it at all. What they're doing when they first turn on is
    measuring the ambient light, then only allowing enough current to flow
    through the filament to generate the illumination required to overcome
    the ambient lighting enough to achieve, locally, the lumens printed
    on the package. They have to do it slowly, though, otherwise the lamp
    will oscillate, which is very annoying. Try this experiment for
    yourself: First, turn on one of the lamps outside on a sunny day and
    notice how bright it gets when it warms up, then take the same lamp
    and turn it on in a dark room. Notice how much brighter it gets?

    That sounds like a no shitter to me, John, but you let that cross
    post slide over to alt.alien.vampire.flonk.flonk.flonk.

    I wonder how many flonkies that will attract ;)
