LED Light Bulbs Advantages And Cons

LED lights isn't a new technology; actually, it is with us since the 1960's. LED light bulbs were in the beginning used as an alternative for incandescent indicators and displays in lab equipment and after a while in Televisions, watches, radios and calculators. LED values have just most recently has reduced enough to make them viable for personal and industrial markets. LED home lighting can have anything from outdoor to Xmas lights. With the present looming energy crisis in South Africa, and pressure forced on governments and businesses alike for more sustainable energy solutions, LED lights have a bright future in space lighting solutions.

Huge benefits 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 hr 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 hrs 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 11 years. With incandescent and fluorescent bulbs, the actual cost of the bulb should include the labor charge and time required to replace them. LED lights virtually get rid of lighting maintenance costs.

The second large advantage 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 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 examine the 80% efficiency of LED lights with the twenty% efficiency of incandescent lights, the optimal selection 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 reducing, replacing a 100W incandescent light bulb with a LED substitute can cost about 5000 rupees. The start up price may appear 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 terms of electricity used. For businesses, using LED lights makes a whole lot of sense because the reduced maintenance costs a lot more than make up for the high start-up price.

Established businesses are doing it

Different blue chip companies and hotels in USA and UK presently use LED lighting solutions. LED lights are used from stair-nose lighting, light line, wall wash lights and signage illumination to colour-changing till numbers and controls, architectural lighting and freezer lighting. These businesses have identified LED as the preferred lighting solution for the coming future. With LED bulb start up prices falling, more companies will follow all these business leaders and discover a painless lighting solution which will last them a decade, and help save them money.
