LED Lighting Pros And Cons

LED lights isn't a new technology; in fact, it is with us from the 1960's. LED light bulbs were at first used as a substitute for incandescent indicators and displays in lab equipment and eventually in Televisions, watches, radios and calculators. LED values have only most recently has reduced enough to make them viable for non commercial and industrial markets. LED home lighting can include anything from outdoor to Xmas lighting. With the present looming energy crisis in South Africa, and pressure exerted 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 hour lifespan, and will last for eleven 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 10000 hours for a fluorescent light. Many businesses find the lifespan of LED light bulbs very attractive - imagine only have to change the signage on a business property once every eleven years. With incandescent and fluorescent bulbs, the true cost of the bulb should include the labor expense and time needed 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 decreased power consumption. LED bulb is capable of converting 80% of the electrical energy used into light energy. The left over 20% electrical energy is left as heat energy. Incandescent light bulbs only convert twenty% of the electrical energy used 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 choice of light bulb is quite noticeable.

Major disadvantages of using LED lighting

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 Rs 5000. The start up cost may look frightening, however LED light bulbs pay for themselves over time because they can work for up to eleven yrs, and saves a lot of money in respect of electricity utilized. 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.

Major 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 lights and freezer lighting. These businesses have recognized LED as the preferred lighting solution for the coming future. With LED bulb start-up rates plummeting, more companies will follow all these business leaders and discover a painless lighting solution that will last them a decade, and save them money.
