A multifaceted reflector is a component found in some lighting fixtures that helps to evenly distribute light across its surface. The reflector works by using a series of small flat mirrors that are positioned at different angles, reflecting light in…

A motion sensor is a device that detects movement or activity within a certain area and triggers an alarm or other response, such as activating a light. Motion sensors are commonly found in security systems, automated lighting systems, and home…

Mercury is a chemical element used in the manufacture of fluorescent and high intensity discharge (HID) light bulbs. This element is heated to create an arc of light, which produces high levels of illumination. When lamp mercury reaches its boiling…

Mean lumens is a term used to describe the average luminous flux output of a light source over its entire rated life. This number can be determined by taking the total lumens of all the individual lamps in a given…

Maximum Overall Length (MOL) is a term used to describe the combined length of a light bulb and its associated socket. MOL is determined by measuring from the tip of the bulb to the base of the socket. The MOL…

A magnetic transformer is an electrical device used in lighting systems which converts alternating current (AC) into direct current (DC). It utilizes a core of magnetically permeable material, typically iron or ferrite, along with windings of wire to create a…

Magnetic induction is a technique used in lighting systems to increase the efficiency of metal halide lamps by creating an alternating magnetic field actuating the gas inside. This alternating magnetic field increases electron mobility which leads to increased lumens output…

Lux (lx) is a unit of measurement for illuminance or the amount of light that falls on a surface area. It is the derived SI unit for measuring illuminance and luminous emittance and is equal to one lumen per square…

Luminous flux is the total amount of visible light emitted by a light source, and is measured in lumens (lm). It is related to luminous intensity, which measures the amount of light emitted from a single point. The higher the…

Luminous efficacy is the ratio of light output to power input for a luminaire or other light source. It is usually expressed in lumens per watt (lm/W) and is a measure of the efficiency of the light source. The higher…

Luminance is the total brightness of a surface or object, as viewed from a particular angle. It is measured in candelas (or lumens) per unit area and is usually expressed in lux or lumens per square meter (lm/m²). Luminance is…
