A typical 2006-era 4 ft (122 cm) T-12 fluorescent lamp (i.e. F34T12) contains about 5 milligrams of mercury. [5] In early 2007, the National Electrical Manufacturers Association in the US announced that "Under the voluntary commitment, effective April 15, 2007, participating manufacturers will cap the total mercury content in CFLs under 25 ...
In the 1970s, 34-watt energy-saving F40T12 fluorescent lamps were intoroduced in the United States. In the 1980s, T8 32-watt lamps were introduced, [8] but unlike the T8 tubes introduced in Europe, these T8s are not retrofits and require new matching ballasts to drive them. These ballasts were originally magnetic, but most today are electronic.
The directive imposes the responsibility for the disposal of waste electrical and electronic equipment on the manufacturers or distributors of such equipment. [5] It requires that those companies establish an infrastructure for collecting WEEE, in such a way that "Users of electrical and electronic equipment from private households should have the possibility of returning WEEE at least free of ...
The design was initiated by the U.S. EPA and the Lighting Research Center in 2004, in order to facilitate the deployment of compact fluorescent light bulbs with replaceable ballasts. [ 1 ] The GU24 fitting is compliant with a 2008 ruling by the California Energy Commission under Title 24 ( California Building Standards Code ) to require high ...
The efficacy of fluorescent tubes ranges from about 16 lumens per watt for a 4 watt tube with an ordinary ballast to over 100 lumens per watt [51] with a modern electronic ballast, commonly averaging 50 to 67 lm/W overall. [52]
Ballasts for sign lighting in the United States, are heavier duty than other ballasts because the cooler outdoor temperatures increase the energy required to start a fluorescent tube. They are sized based on the total tube length used. Typical European 230V series choke ballast 40W T12 or 36W T8 fluorescent lamps.
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]
Waste disposal may be restricted entirely via a disposal ban. The most common and widespread such standard is a prohibition on littering . Where a jurisdiction has authorized a specific place or system for trash collection, deposition or abandonment of trash elsewhere may be subject to civil or criminal penalties. [ 7 ]
