LED Light Bulbs Benefits And Disadvantages

LED lights isn't the latest technology; as a matter of fact, it is around us since the 1960's. LED light bulbs were initially used as a substitute for incandescent indicators and displays in lab tools and eventually in Televisions, different watches, radios and hand calculators. LED costs have just most recently has dropped enough to make them viable for residential and commercial markets. LED Lights can include anything from outdoor to Christmas 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 bright future in space lighting solutions.

Huge advantages of using LED lights

First of all, LED lights are far more efficient than any other lights alternative commercially available at the moment. LED bulbs have a 100000 hour lifespan, and will last for eleven years at continuous operation, or 22 years at 50% operation. Compare this to the approximate lifespan of 5000 hours for an incandescent light bulb and 10000 hours for a fluorescent light. Many 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 needed to exchange them. LED lights virtually eliminate lighting maintenance costs.

The second major benefit and key strength of using LED lighting over 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 twenty% of the electrical energy used into actual light energy, which means that a staggering 80% of electrical energy is lost as heat energy. When you examine the 80% efficiency of LED lights with the 20% efficiency of incandescent lights, the optimal selection of light bulb is quite apparent.

Major drawbacks of using LED lights

The primary limitation is the current 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 substitute can cost about Rs 5000. The start up price may look frightening, however LED light bulbs pay for themselves over time since they can work for up to 11 years, 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 cost.

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 color-changing till numbers and controls, architectural lighting and freezer lighting. These businesses have recognized LED as the preferred lighting solution for the 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 save them money.
