LED Office Lighting: Save Energy – Save Money...

Office lighting can consume anywhere from 20 to 30% of the electricity bill. Until recently, the commonly used light sources in offices were CFLs (compact fluorescent lamps) and incandescent or filament lamps. However, owing to concerns of inefficiency and use of rare materials like mercury and tungsten, LED office lighting fixtures are now finding wide acceptance. Compared to CFLs and incandescent lamps, LED lights use less energy to give out equivalent light output. However, high purchase costs often hold buyers back from buying these devices. However we show you why LED office lighting fixtures can help pay back the invested money much faster than you would expect: LEDs pay back their cost by slashing bills LED lamps emit more lumens of light per watt of energy consumed. They also do not heat up as much as CFLs and incandescent, which give off 80% and 90% of energy as heat respectively. The extra amount of heat also means the air conditioning systems have to work more and consume more power as well. LEDs also have an operating life above 25,000 hours compared to 8000 hours for CFLs and 3000 hours for filament bulbs. So a single LED would remain in operation while multiple conventional lamps are changed during the same period. As we consider the costs over the entire life of the lamp, LED lamps pay back more both in energy costs and new purchases. They are also sturdier than other lamps and easier to install. The output and colour tone can also be changed on specific models. How LEDs work Nick Holonyak Jr. is credited with developing the first visible-spectrum LED while working in GE in 1962. LEDs use semiconductor diodes to produce light using the reverse photoelectric effect-...
