My school is making big efforts to be environmentally friendly - lots of recycling, and can we turn the lights off when not in use please?
Trouble is we’re using flourescent tubes, and having a bit of a difference of opinion. I had always believed that these lights were very efficient once turned on, but required a lot of energy to start. So once they’re on you leave 'em on for the rest of the day.
Does anyone have any input?
