keni asked:
I heard that they use a kick of energy when you first switch them on, then use a lot less while they stay on. Is the initial amount more than, say a normal 60w bulb? If so, what is the length of time where the two use the same amount of energy? This isn’t an exam question - I just want to know if it is worth using energy-saving bulbs where they are used frequently for short periods of time - cupboards, bathrooms etc.

The same amount as traditional typesthe other benefit is they last longer.
The initial surge is only a second or so, so yes, they are more efficient to use anywhere you put them, whether on for just a minute or all night.
For minute they are on for minute they are on for minute they are on for minute they will save money the starting current is less than second so if they will save money the starting current lasts very short time less than 60.
The starting current is less than 60 watt bulb consumes.
