Mercury emits light with high energy - ultraviolet light The tube of a fluorescent bulb is coated with phosphors, which are materials that glow when hit with light or electrons (like a TV screen) The UV light from the mercury is turned into white light by the phosphors, making light we can use Fluorescent bulbs produce about 5x more lumens per watt of electricity than incandescent bulbs Convert about 80% of power to heat, 20% to light New compact bulbs can be used in place of incandescents to save 10% of US energy use Last longer (no thermal shock at turn on) Energy use by other appliances &#9;Appliance&#9;&#9; Energy used(kWh/year) window air conditioner
