LED Lights Pros And Drawbacks
LED lights is not the latest technology; actually, it is around us from the 1960's. LED light bulbs were originally used as a substitute for incandescent indicators and displays in lab tools and after a while in Televisions, different watches, radios and hand calculators. LED prices have just recently has lowered enough to make them viable for non commercial and industrial markets. LED home lighting can have 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.
Major benefits of using LED lights
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 eleven years at continuous operation, or 22 years at 50% operation. Compare this to the approximate lifespan of 5000 hrs for an incandescent light bulb and ten thousand hours for a fluorescent light. Many businesses find the lifespan of LED light bulbs very interesting - 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 needed to replace them. LED lights virtually get rid of lighting maintenance costs.
The second large 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 remaining 20% electrical energy is left as heat energy. Incandescent light bulbs only convert 20% of the electrical energy used into actual light energy, which means that a staggering eighty% of electrical energy is lost as heat energy. If you examine the 80% efficiency of LED lights with the 20% efficiency of incandescent lights, the optimal selection of light bulb is quite understood.
Large disadvantages of using LED lighting
The primary limitation is the present high price of LED light bulbs. Even though the cost of LED lights in South Africa is slowly reducing, replacing a 100W incandescent light bulb with a LED alternative can cost about Rs 5000. The starting cost may seem daunting, but LED light bulbs pay for themselves over time since they can last for up to eleven years, and saves a lot of money in terms of electricity utilized. For businesses, using LED lights makes a whole lot of sense since the reduced maintenance costs a lot more than make up for the steep starting price.
Leading businesses are doing it
Different blue chip companies and hotels in United States and United Kingdom currently use LED lighting solutions. LED lights are used from stair-nose lighting, light line, wall wash lighting and signage illumination to color-changing till numbers and controls, architectural lighting and freezer lighting. These businesses have identified LED as the preferred lighting solution for the future. With LED bulb start up prices plummeting, more companies will follow all these business leaders and discover a painless lighting solution that will last them a decade, and save them money.
