What are low-mercury light bulbs?
Linear fluorescent light bulbs that contain 3.5 to 4 milligrams of mercury are referred to by manufacturers as”low-mercury light bulbs.” The amount of mercury in these light bulbs is considerably less than the amount of mercury in standard linear fluorescent light bulbs, which typically contain from 8 to 14 milligrams of mercury. Manufacturers have made significant mercury reductions in fluorescent light bulbs since the 1990’s and are continuing to make further reductions. Some low-mercury light bulbs can be identified by metal “end caps” (the metal pieces at the end of the linear tube) that are painted green. These are sometimes referred to as “green-tip” bulbs. Low-mercury light bulbs may also identified by green etchings on the lamps. Other linear fluorescent light bulbs may have low mercury content, but this is not indicated on the bulb or packaging. The best way to determine the mercury content of a fluorescent bulb is to contact the bulb manufacturer. EPA encourages the recycling
