Understanding key terminology is essential for making informed decisions about LED lighting and educating decision-makers who may need to become more familiar with professional lighting definitions.

This glossary provides definitions of fundamental terms used in the industry.

LED Lighting Terminology

Specialized drivers designed to meet architectural lighting applications' aesthetic and functional demands, ensuring performance and flexibility.

Controllers that use Bluetooth technology to wirelessly manage and adjust LED lighting settings, often through smartphones or other connected devices.

A measure of the perceived intensity of light emitted from a source, typically influenced by the lumens it produces.

A scale from 1 to 100 measuring how accurately a light source reveals the true colors of objects compared to natural sunlight.

Measured in Kelvin (K), it describes the hue of white light emitted, ranging from warm (yellowish) to cool (bluish).

A digital addressable lighting interface protocol for controlling lighting systems and allowing precise dimming adjustments.

Devices commonly used in stage lighting that control various lighting fixtures through a digital multiplex (DMX) protocol.

The ability to adjust the brightness level of a light source, typically to enhance ambiance or save energy.

The ratio of light output (lumens) to energy consumption (watts), often expressed as lumens per watt (Lm/W).

A semiconductor device that emits light when an electrical current passes through it, widely used for energy-efficient lighting solutions.

A device that regulates the operation of LED lighting systems, including dimming and color adjustments, ensuring optimal performance.

A device that enables users to control the brightness of an LED light source, providing flexibility in lighting levels.

A device that supplies the appropriate voltage and current to power an LED light source, crucial for maintaining efficiency and longevity.

Standard electrical voltage (typically 120V in the U.S.) used in residential and commercial outlets to power lighting systems.

Electrical voltage typically below 50V, commonly used in LED systems, often requiring a transformer to step down the voltage from line voltage.

Indicates the point at which an LED light source will have degraded to 70% of its original brightness, commonly used as a measure of lifespan.

A unit of measurement for the total amount of visible light emitted by a source, higher lumens indicate brighter light.

A measure of lighting efficiency, indicating how much light output (lumens) is generated for every watt of power consumed.

Drivers that use radio frequency (RF) signals to remotely control dimming functions in LED lighting systems.

Silicon-controlled rectifier (SCR) power supplies are compatible with traditional dimming systems, allowing LED lights to dim smoothly.

Smart controllers compatible with WiFi and Bluetooth are used to manage LED lighting systems via mobile apps and smart home devices.

Refers to the perceived color tone of light, with lower Kelvin values (e.g., 2700K) giving a warm, yellowish light and higher values (e.g., 5000K) producing cooler, bluish light.

A unit of power measurement indicating the amount of electrical energy consumed by a lighting system.

Controllers that connect to wireless networks, enabling remote control of LED lighting systems through apps or voice assistants.

Controllers using Zigbee, a low-power wireless communication protocol, to enable smart control of LED lighting in connected environments.
