FAQs - LED Lighting

Up to 20% or more of all energy generated in the UK is used for lighting purposes. Switching to LED lighting can help to reduce the amount of energy consumed for lighting within a building by up to 90%. The savings result in less need for the burning of fossil-based fuels to generate electricity and the production of toxic chemicals and greenhouse gasses.

LED lights can cost more to purchase than traditional incandescent bulbs but as LED lights can use up to 90% less energy the cost is recovered within 1 to 2 years of use.

LED lighting is more energy efficient than traditional incandescent light bulbs. The energy saving difference derives from the technology and science of how the bulb generates light. Incandescent light bulbs generate light by forcing current through a thin tungsten coil. A high proportion of the energy is converted to heat and a low amount to light. LED lights use a semiconductor which is more efficient at generating more of the energy into light with no or very little energy wastage by way of heat generation.
