LED Lights Pros And Disadvantages
LED lighting isn't a new technology; actually, it is with us from the 1960's. LED light bulbs were originally used as a substitute for incandescent indicators and displays in laboratory equipment and eventually in TV's, wrist watches, radios and calculators. LED rates have only most recently has dropped enough to make them viable for residential and commercial 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 same for more sustainable energy solutions, LED lights have a bright future in space lighting solutions.
Major advantages of using LED lighting
First of all, LED lights are far more efficient than any other lights alternative commercially available 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 5000 hours for an incandescent light bulb and 10000 hours for a fluorescent light. Many businesses find the lifespan of LED light bulbs very appealing - imagine only have to alter the signage on a business property once every 11 years. With incandescent and fluorescent bulbs, the actual cost of the bulb should include the labor expense and time required to replace them. LED lights virtually eliminate lighting maintenance costs.
The second major advantage and key strength of using LED lighting above 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 lost 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. If you compare the 80% efficiency of LED lights with the twenty% efficiency of incandescent lights, the optimal selection of light bulb is quite apparent.
Large disadvantages of using LED lighting
The primary limitation is the current 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 start up price may seem daunting, but 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 steep start-up cost.
Major businesses are doing it
Different blue chip companies and hotels in USA and United Kingdom currently use LED lighting solutions. LED lighting are used from stair-nose lighting, light line, wall wash lighting and signage illumination to color-changing till numbers and controls, architectural lighting and freezer lighting. These businesses have recognized LED as the preferred lighting solution for the coming future. With LED bulb start up costs falling, more companies will follow these business leaders and discover a painless lighting solution which will last them a decade, and save them money.
