![]() Ultraviolet radiationĬanadians can be exposed to ultraviolet (UV) radiation from a variety of natural and artificial sources, including the sun, welding equipment, lasers, tanning equipment, and fluorescent lights. With more Canadians using CFLs, some have begun to question their safety, including the level of UV emissions, the electric and magnetic fields (EMFs) they create, and the presence of mercury in the lamps. ![]() The UV then 'excites' the phosphor coating inside the lamp, which emits the light you see. When the lamp is turned on, the mercury vaporizes inside the lamp and becomes 'excited' by the high voltage electricity. They are low-pressure, mercury vapour lamps that produce invisible ultraviolet (UV) rays. Like the old-style fluorescent lights, they use a different method to produce light, which makes them energy-efficient. On this page:įluorescent lights have been around for a long time, and CFLs are the latest variation on the traditional tube fluorescent light. CFLs fit into a standard light bulb socket. ![]() More and more Canadians are replacing regular incandescent light bulbs with more energy-efficient products, such as compact fluorescent lamps (CFLs).
