In 2013, performance requirements will increase further, requiring 40 percent higher efficiency. The fixtures will continue to meet the strict performance; ensuring high quality light output as well as reduced toxins in fixture materials. A range of options will qualify under the new requirements, including fluorescent and LED lighting. [33]
Fluorescent lamps in various embodiments. Since their introduction as a commercial product in 1939, many different types of fluorescent lamp have been introduced.
