LED Light Bulbs Advantages And Cons
LED lights is not a new technology; in fact, it is around us from the 1960's. LED light bulbs were at first used as an alternative for incandescent indicators and displays in lab device and after a while in Televisions, wrist watches, radios and calculators. LED rates have only recently has lowered enough to make them viable for non commercial and commercial markets. LED Lights can have anything from outdoor to Xmas lighting. With the current looming energy crisis in South Africa, and pressure put on governments and businesses alike for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.
Major benefits of using 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 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 appealing - imagine only have to change 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 charge and time needed to replace them. LED lights virtually eliminate lighting maintenance costs.
The second large benefit and key strength of using LED lighting over conventional lighting is the reduced 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 20% 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 examine the 80% efficiency of LED lights with the 20% efficiency of incandescent lights, the optimal selection of light bulb is quite apparent.
Large disadvantages of using LED lights
The primary limitation is the present high cost of LED light bulbs. Even though the price of LED lights in South Africa is slowly decreasing, replacing a 100W incandescent light bulb with a LED alternative can cost about Rs 5000. The start up price may seem daunting, however 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 used. For businesses, using LED lights makes a whole lot of sense since the reduced maintenance costs more than make up for the high start-up cost.
Major businesses are doing it
Various blue chip companies and hotels in United States 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 lighting and freezer lighting. These businesses have recognized LED as the preferred lighting solution for the future. With LED bulb start-up prices plummeting, more companies will follow these business leaders and discover a painless lighting solution that will last them a decade, and help save them money.
