摘要： A low pressure mercury vapor fluorescent lamp includes a lamp vessel having a mercury protective coating on the inner surface of the lamp envelope and a halophosphate phosphor layer. The lamp has a discharge sustaining filling including mercury and a rare gas. The level of mercury is selected such that the lamp has a standard average lamp life of about 20,000 hours while passing the Environmental Protection Agency's Toxicity Characteristic Leachate Procedure (TCLP) test and the State of California's Waste Extraction Test (WET).
