What type of light is used in a laser level?

A laser level uses an LED (light emitting diode). Laser stands for Light Amplification by the Stimulated Emission of Radiation. Basically, when electrons are stimulated they produce light. This light is amplified by mirrors or prisms that collect it into a single laser beam.
