  The value of x depends on how much you pay for electricity
  and how much you pay for flourocent light. Every time you
  turn it on, it loses some hours of life.

  If you pay nothing for the flouro, save electricity and
  turn it off whenever you can. If you pay nothing for the
  electricity, don't turn it off if you expect to turn it
  on again in less than 3 hours. (Which is the life you 
  lose when you turn it on, according to the makers.)

  Here in Stockholm, x = 30 min.
