Low Energy and Fluorescent Bulbs
These contain gases in a tube but have no filament.
The new breed of compact fluorescent (or 'low energy') lamps will only use around 11 watts of power to generate the same light as a normal 60 watt light bulb.
There is no doubt at all that they can save you up to 80% on your electricity bill over the life of the lamp, which can last for up to 5 years (10,000 hours) and if you are using less electricity, you need to generate less electricity and this reduces greenhouse gases, which thin the ozone layer around the earth.
Fluorescent lamps have no filament, they are just a tube with gases in it. Recent technology has reduced the size and improved the efficiency, with many different shapes and power options now available. These lamps are ideal for lights that need to be kept on for a long time i.e. overnight on landings or in hallways.
In the past it was felt that fluorescent light was 'cold' but with the invention of 'warm white' lamps this is no longer the case.
