With the development of LED technology, in particular to reduce the price of LED lights, the technology matures, more and more places to try the LED lights, so we have to calculate specific LED lights in the end it will give us money? You can save much money? Here we are Career high 100W of LED flood light is calculated, we can speculate roughly proportional wattage own data, did not talk much, open test.
100W of LED flood light can replace 300 ~ 400W traditional lamps, with regard to a minimum of 300W to count, Career high 100W of LED flood light price is 229, in the high-end level, the market in general 300W HPS 220 price roughly equal; again counted under electricity, home electricity tariff by 5 hair count, lighting 20 hours a day on average, 360 days per year, then the LED flood light year in electricity is 0.5 * 100W * 5 hours * 360 day / 1000 = 90, and high pressure sodium lamp electricity is 0.5 * 300W * 5 hours * 360 days / 1000 = 270, annual electricity savings of a lamp 180, this cost is quite considerable. This is just from the point of view of electricity.
LED flood light lamp life longer than the high-pressure sodium lamps. High pressure sodium lamp life of 3,000 to 8,000 hours, LED flood light life of 30,000 to 50,000 hours, that life LED flood light is six to 10 times as high pressure sodium lamp, high pressure sodium lamp life of 3000 hours / 5 * 360 = 2 years, LED flood light for 10 years, the annual cost savings of 220 / 2-229 / 10 = 87 yuan. It also is not the money for lights, so it seems, with LED lamps for light not only save money, but also easy.
From the above analysis it seems, with LED lamps for light, with the longer, the more money. Save money every year 180 + 87 = 267 yuan, which is 100W, then 50W save money 133.5,10W26.7, and so on.
