Replacing Standard Lamps with Energy Saving Lights Bulbs can really make a difference to your energy bills. Below we have produced a Costings Table to show you exactly how much you could save with each lamp you replace with a low energy equivalent. It is obvious that an energy saving lamp uses less energy than a standard lamp. but it is not often made clear exactly how much a difference this can make. The Costings Table below details and compares the running costs of a Standard Lamp and a Lumena Low Energy Equivalent, in turn showing the savings you can make on each lamp as a percentage and in GBP.
