This will be a series of articles to help place more light on the topic of Outdoor Lighting and the new SOX (Low Pressure Sodium) lights. Today we have entered an era of energy consciousness and efficiency. We all realize that pollution needs to be reduced and we all want to have lower operating costs.
The data and facts presented in my articles are the foundation to my energy saving audits for outside lighting at private, commercial and public businesses. Some of my clients range from Macy's department stores to the United States Postal Service. As we work together, we are reducing pollution, saving money and saving oil for America.
So why is Low Pressure Sodium Lighting the answer?
Low Pressure Sodium lamps were first introduced in Europe during the 1930s. At that time, they were only as efficient as Mercury Vapor lamps, about 40 lumens per watt. More than 40 years of research and development have increased their efficiency more than four times, making Low Pressure Sodium the world's most economical commercially available light source.
Additionally, continuing development will enable Low Pressure Sodium to attain a theoretical maximum efficiency of 510 lumens per watt compared to a theoretical maximum 385 lumens per watt for high pressure sodium lighting.
My next article will show all the features of Low Pressure Sodium lights.
