LED Light Bulbs Pros And Cons

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 five thousand hours 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 actual cost of the bulb should include the labor charge and time needed to exchange them. LED lights virtually eliminate 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 left 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 20% efficiency of incandescent lights, the optimal selection of light bulb is quite apparent.
Major drawbacks of using LED lights
The primary limitation is the present high cost of LED light bulbs. Even though the cost of LED lights in South Africa is slowly decreasing, replacing a 100W incandescent light bulb with a LED substitute can cost about Rs 5000. The starting cost may appear daunting, but 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 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 start-up price.
