LED Light Bulbs Pros And Drawbacks
LED lighting is not a new technology; as a matter of fact, it has been with us since the 1960's. LED light bulbs were initially used as an alternative for incandescent indicators and displays in lab tools and after a while in TV's, watches, radios and calculators. LED rates have only recently has reduced enough to make them viable for personal and industrial markets. LED home lighting can include anything from outdoor to Christmas lights. With the present looming energy crisis in South Africa, and pressure forced on governments and businesses same 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 available 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 hrs 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 appealing - imagine only have to alter the signage on a business property once every eleven years. With incandescent and fluorescent bulbs, the real 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 major advantage and key strength of using LED lighting above conventional lighting is the reduced power consumption. LED bulb is capable of converting 80% of the electrical energy used into light energy. The remaining 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 examine the 80% efficiency of LED lights with the twenty% efficiency of incandescent lights, the optimal selection of light bulb is quite understood.
Major disadvantages of using LED lighting
The primary limitation is the current high cost of LED light bulbs. Even though the price of LED lights in South Africa is slowly decreasing, replacing a 100W incandescent light bulb with a LED alternative can cost about Rs 5000. The starting cost may appear frightening, but LED light bulbs pay for themselves over time because they can last for up to 11 yrs, 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 cost.
Established businesses are doing it
Various blue chip companies and hotels in United States of America and United Kingdom presently 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 costs plummeting, more companies will follow these business leaders and discover a painless lighting solution which will last them a decade, and help save them money.
