WebEncarta. Microsoft, 1998. "When electric current flows through the filament, it heats the filament to a temperature of about 3000 °C (about 5000 °F), causing the filament to glow and provide light." 3300 K. Incandescent lamps are the most common sources of electric lighting. The most common incandescent lamp is the conventional household bulb. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment , have low manufacturing costs , and work equally well on either alternating current or direct current .
