LED Lights Pros And Disadvantages

LED lighting isn't the latest technology; as a matter of fact, it is with us from the 1960's. LED light bulbs were originally used as a substitute for incandescent indicators and displays in laboratory tools and after a while in Televisions, watches, radios and calculators. LED rates have just most recently has lowered enough to make them viable for residential and industrial markets. LED home lighting can have anything from outdoor to Xmas lighting. With the current looming energy crisis in South Africa, and pressure forced on governments and businesses alike for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.

Large advantages of using 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 hours 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 alter 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 required to exchange them. LED lights virtually get rid of 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 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. When you examine 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 present high price of LED light bulbs. Even though the cost 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 starting cost may seem frightening, however LED light bulbs pay for themselves over time since they can last for up to eleven yrs, and saves a lot of money in terms of electricity used. 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 start-up cost.

Established businesses are doing it

Different blue chip companies and hotels in United States and UK 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 recognized LED as the preferred lighting solution for the coming future. With LED bulb start-up prices plummeting, more companies will follow all these business leaders and discover a painless lighting solution that will last them a decade, and help save them money.
