LED Lighting Pros And Drawbacks
LED lighting is not the latest technology; as a matter of fact, it has been with us since the 1960's. LED light bulbs were in the beginning used as a replacement for incandescent indicators and displays in laboratory equipment and after a while in Televisions, different watches, radios and hand calculators. LED prices have just most recently has lowered enough to make them viable for personal and industrial markets. LED home lighting can have anything from outdoor to Xmas lights. 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 bright future in space lighting solutions.
Large advantages of making use of LED lights
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 five thousand hours 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 required to exchange them. LED lights virtually get rid of lighting maintenance costs.
The second major advantage and key strength of using LED lighting above conventional lighting is the reduced power consumption. LED bulb is capable of converting eighty% 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 used into actual light energy, which means that a staggering eighty% of electrical energy is lost as heat energy. If you examine the 80% efficiency of LED lights with the twenty% 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 price of LED light bulbs. Even though the cost of LED lights in South Africa is steadily decreasing, replacing a 100W incandescent light bulb with a LED substitute can cost about Rs 5000. The starting cost may seem daunting, however LED light bulbs pay for themselves over time since they can work for up to 11 years, and saves a lot of money in terms of electricity utilized. For businesses, using LED lights makes a whole lot of sense because the reduced maintenance costs a lot more than make up for the steep starting price.
Major businesses are doing it
Various blue chip companies and hotels in United States and United Kingdom 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 future. With LED bulb start up costs plummeting, more companies will follow these business leaders and discover a painless lighting solution that will last them a decade, and save them money.
