A laser, unlike an incandescent source, produces a beam in which all the components bear a fixed relationship to each other.
Coloured light or colour can come to us in three ways: 1. Direct colour comes from an incandescent source - one that generates and emits light itself (the sun, a torch, a firework display).

"You have to have incandescent sources to be able to light the space nicely, softly -- to get that warm feel, even in contemporary spaces," says Granville McAnear, a senior designer at Craig Roberts Associates in Dallas.
"As the dancers are illuminated by various incandescent sources, you see them awaken to discover the light within their souls.
Light therapy using light-emitting diodes (LEDs) may offer advantages over conventional light boxes based on fluorescent or incandescent sources.
LEDs can be selected to emit light with energy concentrated in this range, while fluorescent and incandescent sources emit across the visible spectrum.
Optical nanostructures can control the optical absorption and emission properties of surfaces and are therefore being investigated for solar thermophotovoltaics, thermophotovoltaics, solar thermal, infrared sensing, infrared sources, incandescent light sources, and thermal imaging applications, among many others.
First, duplicate samples of both dyes were exposed to an incandescent light source for seven days, and their absorbance measured at specified times.
Data is presented on the marked 3 4 fold improvement in the photostability of HyPer5 over Cy5 following exposure of dyes to incandescent light source.
In the first test, duplicate samples of both dyes were exposed to an incandescent light source for seven days, during that period their absorbance were measured at regular intervals.
