LED Lights Benefits And Cons

LED values have just most recently has reduced enough to make them viable for residential 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 identical for more sustainable energy solutions, LED lights have a bright future in space lighting solutions.

Large benefits of using LED lighting

First of all, LED lights are far more efficient than any other lights alternative commercially accessible 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 attractive - imagine only have to alter the signage on a business property once every eleven years. With incandescent and fluorescent bulbs, the actual cost of the bulb should include the labor expense and time required to exchange 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 80% of the electrical energy used into light energy. The left over 20% electrical energy is lost as heat energy. Incandescent light bulbs only convert twenty% of the electrical energy utilized 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 apparent.

Large drawbacks of using LED lighting

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 alternative can cost about Rs 5000. The starting cost may seem 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 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 steep starting price.

Established businesses are doing it
