Is it more efficient to turn off fluorescent
Date: Around 1993
Is it more efficient to leave fluorescent lights on or to turn
them off for a short period of time?
It is always better to turn off any light if you do not need
them. However, I think what you want to know is -- is it better to turn off a
fluorescent light when leaving a room for only a short time? The answer is
dependant upon several factors, but generally, for most household
applications, it is better to leave the fluorescent lights on if they will be
off for a period of 3 minutes or less. The surge current to start the lamp is
higher than the maintaining current to keep the lamp running.
