The article says that the start up current is the same as 5 seconds normal running. Yes there is a start up surge but it is only very short on modern lamps. The real test would be to fit a kw/h meter to your lamp. Take a reading after a week of it being on continuously, then try another week of switching it on and off as needed.
I was having a quote at work from a lighting engineer a few months ago for zoning some florescent lights so they could be automatically turned on and off as needed to save electricity. He also said that start up current equates to only a few seconds of running power on modern florescent lamps and that they should be turned off when not needed.
