Cost effective LED LED so expensive, why also said it cost-effectivehigh? Yes, LED is quite expensive, but for the cost and benefit, thisis just one of the consideration factors. The same, for now noexpensive LED products, you have to know, this is just oneconsideration!] if we fully considered the cost benefit of words, fromthe whole life cycle, is also said to have the concept of the whole life cycle cost, not just consider the initial cost. Like I said before,LED is more energy-saving than traditional light sources, it is estimated that if all light sources are replaced with LED, you can save 30% energy, lighting, account for almost 20% of humanenergy consumption. For the light source more old more power consumption such as incandescent lamp, through a simplereplacement of LED lighting, energy-saving effect can reach 70%.Longer life of LED, so the whole life period of replacement cost andlower maintenance cost.
