Light Bulb Colour Temperature SpectrumBy Henning Dalhoff

Light bulb colour temperature spectrum This spectrum shows how the overall hue of the light from light bulbs can vary in terms of a calculated characteristic known as colour temperature The light produced by a source such as the Sun or a light bulb will include a range of colours but this can be averaged out to obtain its colour temperature The range shown here is from to Kelvin Seven examples of light bulbs are indicated highpressure sodium standard incandescent halogen three types of metal halide and cool white fluorescent Daylight is Kelvin For this spectrum without the labels or examples see C
