It is reported that a global switch to efficient lighting systems would trim the world`s electricity bill by nearly one-tenth. This page shows all our wall lights that use energy efficient lighting. More information on energy efficient lighting can be found at the foot of the page.
Some incandescent bulbs are very inefficient; converting only about 5% of the energy they receive into light and the UK government is set to ban the sale of the standard incandescent light bulb. Other lamps and lighting equipment that are being scrutinised and may be banned include low-efficiency fluorescent tubes, high-loss "ballasts" for fluorescent tubes, high-loss halogen transformers and mercury discharge lamps.
If you want to reduce your carbon footprint use energy efficient lamps, running on high frequency electronic ballasts and switch off your lights when they are not required both at work and at home.
