Like all lightbulbs, light-emitting diodes (LEDs) produce illumination by turning a given amount of electric current into light. LEDs perform this conversion more efficiently than standard incandescent bulbs: According to the U.S. Department of Energy, a typical Energy Star-rated LED uses 20 to 25 percent of the energy that an incandescent bulb uses; the LED lasts up to 25 times longer, too. The amount of light a bulb generates can be measured in a unit called lumens. Electrical power is measured in a unit called watts. Due to their methodology of converting electricity into light, LED bulbs feature a higher ratio of lumens to watts than incandescent bulbs.
Voltage Optimisation (with 100% guarantee on how much you will save)
Voltage Optimisation is beneficial when the electricity supply to your site is at a higher voltage level than needed, resulting in excessive energy consumption and high electricity bills. Voltage optimisation systems work to optimise the outgoing voltage without compromising the supply. One of the reasons why voltage optimisation is so effective is that the average voltage supplied from the National Grid is 242V (although it can be as high as 253V) where as the nominal UK voltage is 230V.
