Does frequently switching a fluorescent light, on and off, shorten its life span?

Yes, unfortunately that’s true. Therefore it is recommended that they be used where the lamp would be lit for a certain amount of time, and not switched off and on every few minutes. On the other hand, it does not mean that you should keep your fluorescent lights on all the time even if they aren’t actually being used. This will also be a waste of energy.
