What sorts of lamps have you in your school? |

Filament bulb
Filament lamps waste a lot of electrical energy as heat. They should
only be used in places where lights are lit for short periods (e.g.
store rooms) |
Strip lamps
Strip lamps waste very little electrical energy as heat. They should be
used in places where lights are lit for long periods (e.g. classrooms). |

Compact fluorescent lamp
Compact fluorescent lamps (CFLs) waste very little electrical energy as
heat. They should be used in places where lights are lit for long
periods. |
