Replace standard lightbulbs with low energy CFL bubs

Capital cost is typically £2 - £5 per bulb. The energy savings available is around 80% over standard bulbs.



You should aim to remove as many standard light bulbs as possible. Low energy compact fluorescent (CFL) bulbs have been on the market for some time. Although compact fluorescent bulbs cost considerably more to buy outright, they use around 20% of the energy of standard bulbs, and last around 8 times as long. The payback period for installing low energy lighting is typically less than one year.

Low energy bulbs are available in bayonet or screw fittings and in wattages to give the light output of all the standard bulb range.

You should especially aim to install low energy lighting in areas that have frequent occupancy or where lights are left on for long periods of time.
