That is to say, the myth of leaving the switch on, so that you does not waste energy by turning it on several times, is just that: a myth.
There is one exception to this rule: fluorescent bulbs do not last as long if you switch them on and off repeatedly.
Fluorescent lights: if you are only nipping out, you should leave them on, since these bulbs "suffer" each time they are switched on. If the light bulb blows, the cost of buying a new one is greater than the energy you would save.
Halogen and LED lights: these do not “suffer” when you turn them on; therefore it is always advisable to switch them off, even if you are just nipping out.
Paying less, is it possible?
It is also convenient to consider rates that allow you to have the peace of mind that, whatever you consume, you will always pay the same amount or perhaps even less.
