Saving Electricity?

They tested this on MythBusters. :o

From Wikipedia:

Myth statement Status Notes

Leaving a light on will save electricity. Busted Through numerous tests, the MythBusters calculated that the power surge from turning on a light would only consume as much power as leaving it on for a fraction of a second (except for fluorescent tube lights; the startup consumed about 23 seconds' worth of power). Furthermore, the wear and tear of turning the light on and off repeatedly did not reduce the bulb's total life expectancy enough to offset the increased electricity usage. Therefore, it is far more economical to turn a light off rather than leaving it on.
