Nowadays, the penetration of LED is increasing. Solar road stud markers also use LED to emit lights. Recently, the US media announced the top 10 cities of LED adoption rate. It is ranked by the percentage of residents who bought at least one LED bulb last year. As can be seen from the figure below, cities such as Seattle, Minneapolis and Oklahoma City are leading the way in the adoption of LEDs. But there is still a long way to go for them. According to research, less than 20% of residential lighting outlets in the United States use LED bulbs, which means millions of homes don't use this high-quality energy-saving light source.Less than 20% of residential lighting outlets in the United States use LED bulbs, which means millions of homes don't use this high-quality energy-saving light source.
By replacing a 60 watt bulb with an LED, you can save up to $130 in energy costs, which is enough to buy 40 lattes, buy 16 movies or other delicious items. In fact, replacing ordinary bulbs with LED usually costs $5 or less, and can have a positive impact on the environment. The solar road stud markers with LED are capable of working for up to 10 days with just four hours of charge, and cost the same amount over the course of their life as traditional reflective road stud markers. Solar road stud cost £30 and last for between eight and 10 years. By contrast cats eyes cost around £10 and last for between two and three years before they need replacing.
If we change all the traditional reflective road stud or electrical lights to solar road stud markers with LED, a large amount of money will be saved as well as be environment friendly.
