LED Lighting Advantages And Drawbacks

LED lighting isn't a new technology; as a matter of fact, it has been with us since the 1960's. LED light bulbs were originally used as an alternative for incandescent indicators and displays in laboratory device and after a while in Televisions, wrist watches, radios and calculators. LED values have only recently has dropped enough to make them viable for residential and commercial markets. LED Lights can include anything from outdoor to Xmas lights. With the present looming energy crisis in South Africa, and pressure put on governments and businesses identical for more sustainable energy solutions, LED lights have a bright future in space lighting solutions.

Large advantages of making use of LED lighting

First of all, LED lights are far more efficient than any other lighting alternative commercially accessible at the moment. LED bulbs have a 100000 hr lifespan, and will last for 11 years at continuous operation, or 22 years at fifty% operation. Compare this to the approximate lifespan of five thousand hrs for an incandescent light bulb and ten thousand hours for a fluorescent light. Many businesses find the lifespan of LED light bulbs very interesting - imagine only have to change the signage on a business property once every eleven years. With incandescent and fluorescent bulbs, the actual cost of the bulb should include the labor charge and time required to exchange them. LED lights virtually eliminate lighting maintenance costs.

The second major benefit and key strength of using LED lighting over conventional lighting is the reduced power consumption. LED bulb is capable of converting eighty% of the electrical energy used into light energy. The left over 20% electrical energy is left as heat energy. Incandescent light bulbs only convert 20% of the electrical energy utilized into actual light energy, which means that a staggering 80% of electrical energy is lost as heat energy. When you compare the 80% efficiency of LED lights with the twenty% efficiency of incandescent lights, the optimal selection of light bulb is quite understood.

Major drawbacks of using LED lights

The primary limitation is the current high cost of LED light bulbs. Even though the price of LED lights in South Africa is slowly reducing, replacing a 100W incandescent light bulb with a LED alternative can cost about Rs 5000. The starting cost may look frightening, however LED light bulbs pay for themselves over time because they can last for up to eleven years, and saves a lot of money in terms of electricity used. For businesses, using LED lights makes a whole lot of sense since the reduced maintenance costs more than make up for the high start-up price.

Established businesses are doing it

Various blue chip companies and hotels in USA and UK presently use LED lighting solutions. LED lights are used from stair-nose lighting, light line, wall wash lighting and signage illumination to colour-changing till numbers and controls, architectural lights and freezer lighting. These businesses have identified LED as the preferred lighting solution for the coming future. With LED bulb start-up prices falling, more companies will follow these business leaders and discover a painless lighting solution that will last them a decade, and save them money.
