Optimistic forecasts : large-scale LED lighting especially commercial LED light including theRGB LED flood light will replace traditional lighting since 2015. ​​LED lighting would with the cost analysis U.S. Sandia National Laboratories have made to achieve the third lighting revolution: cost of investment is the costs to buy a light bulb ( per trillion lumens ) allocated to the entire life cycle，the operating cost refers to the cost of a light bulb at runtime ( lumens per trillion ), the cost of ownership is the investment costs and operating costs and reflects the entire life cycle of the total cost of a bulb from the purchase to the end of life.

The initial investment costs in RGB LED flood light and other commercial or industrial and household LED light is currently high, but the operating costs have been lower than that of the incandescent lamp , the total cost of ownership is still far higher than that of incandescent and fluorescent lamps. LED cost of ownership down to $ 0.77 / hour trillion lumens in 2012, which has been lower than $ 1 / trillion lumens fluorescent lamps, LED cost of ownership will be reduced to $ 0.48 / Siu lumens in 2020, only half of fluorescent lamps .

This revolutionary replace lighting will produce three major benefits: savings in energy consumption and reduce carbon dioxide emissions and less pollution.

Reduce energy consumption

About one-third of the primary energy is used to generate electricity in the United States , 20% of electricity used for lighting, assuming the market share of incandescent, fluorescent and high-pressure gas discharge lamp is respectively 42 %, 41% , 17% in current lighting market, the total efficiency of lighting is about 45-65lm / W. If the luminous efficiency of commercial RGB LED flood light and other commercial or industrial and household LED lighting can achieve 150-200lm / W , and all to replace the traditional lighting , the total lighting efficiency can be more than doubled.

In China , the total electricity consumption accounts for about 12% of electricity for lighting， China’s total electricity generation was 2.2 trillion degrees in 2004, even at the 5 percent annual growth rate conservatively expects，the total generating capacity will reach 3 trillion degree by 2014 in China, lighting electricity consumption will reach about 360 billion degrees, if saving half of electricity for lighting is 180 billion kWh, equivalent to an annual generating capacity of the Three Gorges power Station for all units .

According to the current situation in terms of thermal power generating units , each unit of electricity consumes 300-400 grams coal , take 350 grams / kWh compromise data to calculate， the national annual savings in standard coal is up to 63 million tons.Browsing http://www.lead-lighting.com/led-flood-light/led-flood-light-rgb-series.htm for more information about the RGB LED flood light.
