LED Light Bulbs Pros And Drawbacks

LED lights isn't a new 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 device and later in Televisions, different watches, radios and calculators. LED costs have just recently has lowered enough to make them viable for non commercial and industrial markets. LED Lights can include anything from outdoor to Christmas lighting. With the current looming energy crisis in South Africa, and pressure put on governments and businesses alike for more sustainable energy solutions, LED lights have a bright future in space lighting solutions.

Huge advantages of making use of LED lights

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 11 years at continuous operation, or 22 years at 50% operation. Compare this to the approximate lifespan of five thousand hrs for an incandescent light bulb and 10000 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 11 years. With incandescent and fluorescent bulbs, the true cost of the bulb should include the labor expense and time needed to exchange them. LED lights virtually get rid of lighting maintenance costs.

The second major benefit and key strength of using LED lighting over conventional lighting is the decreased 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 twenty% of the electrical energy used 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 apparent.

Large drawbacks of using LED lighting

The primary limitation is the present high cost 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 alternative can cost about Rs 5000. The start up cost may appear frightening, but LED light bulbs pay for themselves over time because they can last 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 since the reduced maintenance costs more than make up for the high starting cost.

Leading businesses are doing it

Different blue chip companies and hotels in United States of America and UK presently use LED lighting solutions. LED lighting 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 recognized LED as the preferred lighting solution for the 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 save them money.
