LED Light Bulbs Pros And Drawbacks

LED lights is not a new technology; in fact, it has been around us from the 1960's. LED light bulbs were initially used as a replacement for incandescent indicators and displays in laboratory device and after a while in TV's, wrist watches, radios and hand calculators. LED costs have only recently has reduced enough to make them viable for non commercial and commercial markets. LED Lights can have anything from outdoor to Christmas 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 lights

First of all, LED lights are far more efficient than any other lighting alternative commercially available at the moment. LED bulbs have a 100000 hour lifespan, and will last for 11 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. A number of businesses find the lifespan of LED light bulbs very attractive - 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 needed to replace them. LED lights virtually eliminate lighting maintenance costs.

The second major advantage and key strength of using LED lighting over conventional lighting is the decreased power consumption. LED bulb is capable of converting eighty% 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 utilized into actual light energy, which means that a staggering eighty% of electrical energy is lost as heat energy. If you compare the 80% efficiency of LED lights with the 20% efficiency of incandescent lights, the optimal choice of light bulb is quite apparent.

Large disadvantages of using LED lights

The primary limitation is the current high price 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 substitute can cost about 5000 rupees. The starting price may look daunting, however LED light bulbs pay for themselves over time since 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 high starting price.

Leading businesses are doing it

Various blue chip companies and hotels in United States of America and UK currently use LED lighting solutions. LED lighting are used from stair-nose lighting, light line, wall wash lights 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 these business leaders and discover a painless lighting solution that will last them a decade, and help save them money.
