Bulbs cheaper in long run

CLLR ALLANSON (10/3/11) is concerned that some low-energy light bulbs are relatively expensive to buy and may not last as long as it says on the packet.

However, the major cost of a light bulb comes from using it, not from buying it.

For example a 100w incandescent bulb might cost 30p to buy but during its estimated 1000 hour lifetime will use 100kWh of electricity and, at a typical 12p per kWh, cost £12 to run. The low energy equivalent would only cost about £3 to run and would be worth it even if it didn’t have a longer lifetime.

It would be a pity if anyone was put off using low-energy bulbs by the councillor’s comments.
