 JK> A member of my congregation says that it is cheaper to leave
 JK> a light on all day long than it is to turn it on and off 
 JK> twice, whether florescent or incandescent.  Is this true? 
 JK>  Can anyone point me to published information? 
 TE> I don't know about cost, but for incandescents, the bulb will last
 TE> much longer if left on, as opposed to constantly turning it on and off.
 TE> This is caused by the temperature change expanding and contracting the
 TE> filament, making it brittle and shortening it's life.  Of course, the
 TE> cost is very relative to the price per kilowatt/hour, the cost of the
 TE> light bulbs, and the frequency & duration of switching it on and off. 
 TE> Oh, how a geek like myself can make a simple idea sound so complicated.
