LED Light Bulbs Pros And Drawbacks

LED lights isn't a new technology; in fact, it is around us since 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 TV's, watches, radios and calculators. LED values have just recently has lowered enough to make them viable for personal and commercial markets. LED Lights can have anything from outdoor to Christmas lights. With the current looming energy crisis in South Africa, and pressure put on governments and businesses identical for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.

Huge advantages 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 11 years at continuous operation, or 22 years at 50% operation. Compare this to the approximate lifespan of five thousand hours for an incandescent light bulb and 10000 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 eleven years. With incandescent and fluorescent bulbs, the true cost of the bulb should include the labor charge and time needed to exchange them. LED lights virtually eliminate lighting maintenance costs.

The second major benefit and key strength of using LED lighting above conventional lighting is the reduced power consumption. LED bulb is capable of converting eighty% of the electrical energy used into light energy. The left over 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 eighty% of electrical energy is lost as heat energy. When 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 present high price of LED light bulbs. Even though the price of LED lights in South Africa is steadily reducing, replacing a 100W incandescent light bulb with a LED substitute can cost about Rs 5000. The starting cost may seem daunting, but LED light bulbs pay for themselves over time since they can last 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 price.

Leading businesses are doing it

Different blue chip companies and hotels in United States of America and United Kingdom currently use LED lighting solutions. LED lights are used from stair-nose lighting, light line, wall wash lighting and signage illumination to color-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 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.
