LED Light Bulbs Benefits And Disadvantages

LED lights isn't a new technology; as a matter of fact, it is around us since the 1960's. LED light bulbs were in the beginning used as a replacement for incandescent indicators and displays in laboratory device and eventually in TV's, wrist watches, radios and hand calculators. LED values have just recently has reduced enough to make them viable for non commercial and commercial markets. LED Lights can have anything from outdoor to Christmas lighting. With the current looming energy crisis in South Africa, and pressure forced on governments and businesses same for more sustainable energy solutions, LED lights have a bright future in space lighting solutions.

Huge benefits of using LED lights

First of all, LED lights are far more efficient than any other lights alternative commercially available at the moment. LED bulbs have a 100000 hour lifespan, and will last for 11 years at continuous operation, or 22 years at fifty% operation. Compare this to the approximate lifespan of 5000 hrs for an incandescent light bulb and ten thousand hours for a fluorescent light. A number of businesses find the lifespan of LED light bulbs very attractive - imagine only have to alter the signage on a business property once every 11 years. With incandescent and fluorescent bulbs, the real cost of the bulb should include the labor expense and time needed to exchange them. LED lights virtually get rid of lighting maintenance costs.

The second large advantage and key strength of using LED lighting over conventional lighting is the decreased power consumption. LED bulb is capable of converting 80% of the electrical energy used into light energy. The remaining 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 eighty% 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 choice of light bulb is quite apparent.

Large disadvantages of using LED lighting

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

Leading businesses are doing it

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