What is the difference between ordinary bulbs, energy saving, halogen and LEDs in
terms of energy consumption?
Good lighting in the home is important for appearance, comfort, security and safety.
We now have a bewildering choice of lights for the home and it is important to use
the correct ones for each purpose. Our advice is as follows:
Ordinary light bulb – these should only be used in light fittings which are
seldomly used, for instance a light in a loft or cupboard.
Energy saving lamp – these use 80% less energy than ordinary light bulbs
and should last at least 6 times longer and can often pay for themselves in the
first year. Wherever possible use these in place of ordinary light bulbs.
Halogen lights – these use around 20% less energy than ordinary light bulbs,
however because they are often used in large numbers they can result in higher electricity
bills. Therefore try to avoid using halogen lighting in areas where appearance is
less important such as utility rooms. Also look out for low energy halogen replacement
lamps which are now available.
LED lighting is a fast developing area which is expected to provide very
efficient lighting and long lamp lifetimes in the future. LED lamps are now available
which are equal to or slightly less efficient than energy saving lamps. However
the current models available are only suitable for uses such as desk lamps and under
cupboard lighting.
