LED Lights Advantages And Disadvantages
LED lights isn't a new technology; actually, it is with us from the 1960's. LED light bulbs were in the beginning used as an alternative for incandescent indicators and displays in laboratory equipment and eventually in Televisions, watches, radios and calculators. LED costs have just most recently has reduced enough to make them viable for residential and commercial markets. LED Lights can have anything from outdoor to Christmas lighting. With the current looming energy crisis in South Africa, and pressure exerted on governments and businesses same for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.
Large advantages of making use of LED lighting
First of all, LED lights are far more efficient than any other lights 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 ten thousand 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 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 eliminate lighting maintenance costs.
The second large 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 eighty% of electrical energy is lost as heat energy. When you compare the 80% efficiency of LED lights with the 20% efficiency of incandescent lights, the optimal selection of light bulb is quite understood.
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 alternative can cost about Rs 5000. The start up price may look frightening, but LED light bulbs pay for themselves over time because they can work for up to 11 yrs, and saves a lot of money in terms of electricity utilized. For businesses, using LED lights makes a whole lot of sense since the reduced maintenance costs a lot more than make up for the steep starting cost.
Major businesses are doing it
Different blue chip companies and hotels in USA and United Kingdom presently use LED lighting solutions. LED lighting 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 coming future. With LED bulb start up prices falling, more companies will follow all these business leaders and discover a painless lighting solution which will last them a decade, and save them money.
