LED Light Bulbs Pros And Drawbacks

LED lighting isn't a new technology; as a matter of fact, it is around us from the 1960's. LED light bulbs were originally used as a replacement for incandescent indicators and displays in lab equipment and eventually in TV's, wrist watches, radios and hand calculators. LED rates have only recently has lowered enough to make them viable for residential and commercial markets. LED home lighting can have anything from outdoor to Xmas 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 advantages of using 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 hr 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 interesting - imagine only have to alter the signage on a business property once every eleven years. With incandescent and fluorescent bulbs, the actual cost of the bulb should include the labor expense and time needed to exchange them. LED lights virtually eliminate lighting maintenance costs.

The second major 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 left over 20% electrical energy is lost as heat energy. Incandescent light bulbs only convert 20% of the electrical energy utilized into actual light energy, which means that a staggering 80% of electrical energy is lost as heat energy. If you compare the 80% efficiency of LED lights with the twenty% efficiency of incandescent lights, the optimal selection of light bulb is quite understood.

Large disadvantages of using LED lights

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 substitute can cost about 5000 Rs. The start up cost may look daunting, but LED light bulbs pay for themselves over time since they can work for up to eleven yrs, and saves a lot of money in respect of electricity used. 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 start-up cost.

Established businesses are doing it

Different blue chip companies and hotels in United States and United Kingdom currently use LED lighting solutions. LED lights are used from stair-nose lighting, light line, wall wash lights and signage illumination to color-changing till numbers and controls, architectural lighting and freezer lighting. These businesses have recognized LED as the preferred lighting solution for the coming future. With LED bulb start up rates 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.
