LED Lights Pros And Drawbacks

LED lights is not the latest technology; in fact, it is around us since the 1960's. LED light bulbs were at first used as a substitute for incandescent indicators and displays in laboratory tools and eventually in Televisions, watches, radios and calculators. LED values have just most recently has dropped enough to make them viable for non commercial and commercial markets. LED home lighting can have anything from outdoor to Xmas lights. With the current looming energy crisis in South Africa, and pressure forced on governments and businesses alike for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.

Major benefits 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 eleven 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 10000 hours for a fluorescent light. A number of businesses find the lifespan of LED light bulbs very attractive - imagine only have to change 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 required to exchange them. LED lights virtually get rid of lighting maintenance costs.

The second major 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 lost as heat energy. Incandescent light bulbs only convert twenty% of the electrical energy utilized into actual light energy, which means that a staggering eighty% of electrical energy is lost as heat energy. If you compare the 80% efficiency of LED lights with the 20% efficiency of incandescent lights, the optimal selection of light bulb is quite understood.

Large drawbacks of using LED lights

The primary limitation is the present high cost of LED light bulbs. Even though the cost of LED lights in South Africa is steadily reducing, replacing a 100W incandescent light bulb with a LED substitute can cost about 5000 rupees. The starting price may seem daunting, however LED light bulbs pay for themselves over time since they can last for up to eleven years, and saves a lot of money in respect of electricity utilized. For businesses, using LED lights makes a whole lot of sense since the reduced maintenance costs more than make up for the steep starting cost.

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 recognized LED as the preferred lighting solution for the 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.
