Cost-effective of LED lighting

　　Yes, LED expensive, but for the cost-effectiveness is concerned, this is just one of the considerations. (Similarly, for now not expensive LED products, you have to know, this is just one of the considerations!)

　　If we consider the overall cost-effectiveness, then from the full life cycle perspective, that is to have the concept of life-cycle costs, not just consider the initial cost. Like I said before, LED is more energy efficient than conventional light sources, it is estimated that if all are replaced by LED light source, you can save 30% of energy, and lighting, accounting for almost 20% of human energy consumption. For the older and more power light sources such as incandescent, by simply replacing the LED bulbs, we can achieve 70% energy savings.

　　But wait, more than that. LED's last longer, so replacement costs and lower maintenance costs during the whole life.

　　LED infrared radiation is almost negligible, compared to traditional light sources generate less heat, so the lower the energy consumption of air conditioning systems. LED can be more flexible control by the control system, including switching and dimming through staff and daylight sensors, greatly expanding the energy-saving potential.

　　Finally, led more secure and conducive to recovery, unlike many traditional light sources, because it contains hazardous substances such as mercury, require special equipment and complicated process when recycled.
