LED Lights Advantages And Drawbacks

LED lights is not the latest technology; in fact, it is with us from the 1960's. LED light bulbs were initially used as an alternative for incandescent indicators and displays in lab device and after a while in TV's, wrist watches, radios and calculators. LED prices have only recently has dropped enough to make them viable for non commercial and industrial markets. LED Lights can include anything from outdoor to Christmas lighting. With the present looming energy crisis in South Africa, and pressure exerted on governments and businesses same for more sustainable energy solutions, LED lights have a vibrant future in space lighting solutions.

Huge advantages of making use of 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 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. A number of businesses find the lifespan of LED light bulbs very interesting - 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 charge and time required to exchange them. LED lights virtually get rid of lighting maintenance costs.

The second major advantage and key strength of using LED lighting over conventional lighting is the reduced power consumption. LED bulb is capable of converting 80% of the electrical energy used into light energy. The left over 20% electrical energy is left 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 noticeable.

Major disadvantages of using LED lights

The primary limitation is the current 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 5000 rupees. The starting price may seem daunting, however LED light bulbs pay for themselves over time because they can last for up to eleven years, 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 more than make up for the high starting cost.

Established businesses are doing it

Various blue chip companies and hotels in United States and United Kingdom presently use LED lighting solutions. LED lighting 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 identified LED as the preferred lighting solution for the coming future. With LED bulb start-up costs falling, more companies will follow these business leaders and discover a painless lighting solution that will last them a decade, and save them money.
