What is the preferable lighting for courtyard

I am an environmental enthusiasts, I often study energy-saving products, LED lighting as the fourth generation of lighting products is known for their eco-friendliness, LED floodlights and LED tunnel lights are mainly used for outdoor lighting, LED floodlights are used in stadiums, squares, large commercial buildings, fountains, parks and other commercial lighting and public lighting, LED tunnel lights is used for traffic lighting, they are high-power LED light, and LED tubes, LED bulbs, LED ceiling lamp, LED panels are mainly used for interior lighting,the courtyard as the outdoor environment because the place is relatively wide, mostly using LED floodlights.

Why LED flood lights have better effect on energy-saving relative to traditional light is because that the LED floodlight adopts semiconductor light-emitting principle, reducing large amounts of luminous infrared and ultraviolet light generated by the inert gases containing in the energy-saving lamps and fluorescent lamps and light pollution, and the LED flood light has no mercury, lead and other heavy metals that hazards human and environment, the pink Lane of the energy-saving lamps and fluorescent light is added a small amount of heavy metals, so LED floodlight doesn't cause secondary pollution to the environment, so it is known as environmental protection, low-voltage constant current driver converts alternating current into direct current so that the light emitted is more stable, reducing the flicker of light and not to hurt the eyes, but also improve the effective utilization of current, saving the waste of current into heat, so energy saving.

Of course, what I installed in my courtyard is also LED floodlights, at the beginning ，I also worried about which LED light is best for my yard, I naturally considered finding affordable products, I have some of the engineering and designing friends, they are often associated with lighting designed to deal with, my engineer friend Dick is primarily responsible for construction site lighting, their projects that is developed and designed  such as stadiums, subways are also using LED floodlights and LED tunnel lights, they are often cooperate with a Chinese LED manufacturing companies, he is always talking about topic of LED lighting applied as the energy saving lighting in the 21 century, so I surely want to seek his advice when deciding to use LED lighting, and he recommended me to buy from a Chinese LED lighting manufacturers,I didn't made up my mind until I viewed their Home www.lead-lighting.com/products/bid19-1.htm , because I rarely see business website that specialize in thoughtful design and detailing, I asked the price, they answered in detail and warm service made me decision in this attitude of professional companies to buy good products, I and my friend together ordered 10 LED floodlight, although such a small order for such high-volume businesses would not be considered, but they still individually produced for us, plus，when arrived less than a week delivery schedule, they specially talked on the phone to tell us special attention, the LED floodlights have been used for almost a year until now, there has been nothing problem with starting，replacement, glare, and it has saved us an average of nearly one hundred electricity bills each month.
