Incandescent Light Bulb Color Temperature

When it reaches a temperature of 2 700º kelvin about 4 400º f or 2 426º celsius its glow will roughly match the colour of light emitted by your typical incandescent lightbulb a rather yellowish colour.

Incandescent light bulb color temperature.

Here s a breakdown of light bulb color temperature. The three primary types of color temperature for light bulbs are. Household fixtures are commonly found in color temperatures on the kelvin scale of 2700k warm incandescent 3000k warm white halogen and 3500k household fluorescent. You can actually determine the temperature of hot iron by measuring its color.

Long life bulbs take advantage of this trade off in applications such as traffic signal lamps. When you think incandescent you know what light bulb color temperature to expect. Color temperature is approximately proportional to v 0 42. The surface temperature of incandescent light bulbs varies from 150 to more than 250 degrees whereas compact fluorescent light bulbs have a surface temperature of 100 degrees fahrenheit.

The range of color temperature. Traditionally incandescent bulbs have given off a warm yellow colored light. Most of the common household incandescent bulbs were 2700k where halogens were around 3000 3500k. An incandescent light bulb.

Compact fluorescent light bulbs typically last longer than incandescent bulbs and vary in color temperatures. How to choose the right kelvin color temperature. This light gives a warm and cozy. When a piece of metal is heated the color of light it emits will change.

Light bulb color temperature is represented in the unit of absolute temperature kelvin noted by the symbol k. Soft white 2 700 to 3 000 kelvin is warm and yellow the typical color range you get from incandescent bulbs. Led bulbs on the other hand are available in a variety of colors from classic warm white to cool bluish white that mimics natural daylight.

In the old days of lighting where most lighting options were incandescent color temperature was not a big issue. The color temperature of daylight varies but is often in the 5000k to 7000k range. Soft white 2700k 3000k bright white cool white 3500k 4100k and daylight 5000k 6500k. A 5 reduction in voltage will double the life of the bulb but reduce its light output by about 16.

The higher the degrees kelvin the whiter the color temperature. Color temperature is a description of the warmth or coolness of a light source.
