Energy Efficient Lamps Explained

Lamp types

The table below details all common lamp types against efficiency and lamp life. Please note that neither tungsten filament nor low voltage halogen are 'energy efficient'. The technological progress of LED's will ensure that most will conform in the near future, however, very few are deemed 'energy efficient' at the moment. The most popular 'energy efficient' lamps for domestic residences are the linear and compact fluorescents followed by cold cathode. Please see the chart below for further details on their colour rendering properties as well as the colour temperatures that are available.

Energy Efficient Lamps

 Compact Fluorescent lamps (CFL’s)

Compact fluorescent lamps have high light output with low energy usage. A 15-watt compact fluorescent yields the same amount of light as a 60-watt incandescent lamp thereby providing the equivalent amount and quality of light as a traditional lamp whilst consuming only a ¼ of the energy. CFL’s can be used as a replacement in incandescent fittings making them a practical and energy efficient alternative. 

These formally unattractive and cold-coloured lamps have undergone huge technological advances, where smaller, more flexible lamps now exist. Colour temperatures can be changed, some lamps can be dimmed and the wide assortment of size, shape and wattage enables their greater usage.

Linear Fluorescent lamps

 

Metal Halide lamps

 
Light Emitting Diode lamps

 
Cold Cathode lamps

The slightly higher initial costs of all energy efficient lamps are off-set in lower maintenance and running costs.

All energy efficient lamps need to be disposed of correctly.  Please see the section on lamp recycling for more information.
