LED rates have just recently has dropped enough to make them viable for personal and industrial markets. LED home lighting can include anything from outdoor to Christmas lighting. 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 vibrant 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 accessible at the moment. LED bulbs have a 100000 hr 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 ten thousand hours for a fluorescent light. A number of businesses find the lifespan of LED light bulbs very attractive - imagine only have to change 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 needed to exchange 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 decreased power consumption. LED bulb is capable of converting eighty% 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 20% efficiency of incandescent lights, the optimal choice of light bulb is quite noticeable.

Major disadvantages of using LED lights

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 substitute can cost about 5000 rupees. The start up price may appear frightening, but LED light bulbs pay for themselves over time since they can work 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 because the reduced maintenance costs a lot more than make up for the high starting cost.
