LED Light Bulbs Pros And Disadvantages

LED lighting is not the latest technology; as a matter of fact, it is with us since the 1960's. LED light bulbs were in the beginning used as a replacement for incandescent indicators and displays in lab tools and eventually in Televisions, wrist watches, radios and calculators. LED values 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 put on governments and businesses same for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.

Large benefits of using LED lights

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 five thousand hours for an incandescent light bulb and ten thousand hours for a fluorescent light. Many 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 required to exchange them. LED lights virtually eliminate 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 left over 20% electrical energy is left as heat energy. Incandescent light bulbs only convert 20% of the electrical energy utilized 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 20% efficiency of incandescent lights, the optimal choice of light bulb is quite noticeable.

Large disadvantages of using LED lights

The primary limitation is the present high price of LED light bulbs. Even though the price of LED lights in South Africa is steadily decreasing, replacing a 100W incandescent light bulb with a LED substitute can cost about 5000 rupees. The start up cost may appear daunting, however LED light bulbs pay for themselves over time because they can work for up to eleven yrs, and saves a lot of money in respect of electricity utilized. 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.

Established businesses are doing it

LED lighting are used from stair-nose lighting, light line, wall wash lighting and signage illumination to color-changing till numbers and controls, architectural lighting and freezer lighting.
