Incandescent light bulb max wavelength range
WebJun 2, 2016 · The light in an incandescent light bulb is really just that effect occurring in a contained, controlled environment. As the filament continues to burn, particles fly off the filament. And when there are no more particles to burn, the light bulb burns out, which typically takes place 800-1,200 hours into the life of the incandescent light bulb.

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. WebIndeed, the spectral flux in wavelength of an incandescent bulb is actually greater in the 700-800 nm range than in the visible spectrum, as shown in this image. In terms of where the consumed energy goes, incandescent bulbs are essentially primarily electric heaters, that secondarily have a side effect of producing visible light.
