Another type of lighting is strip a phosphor coating making it fluorescent, so that it produces light. The color of the type of gas that is used. Alternatively, metal vapors can be used instead of a gas. For example, mercury vapor glows yellow. Sodium vapor lights are sometimes used in street lighting.
