Kelvin is a unit of measurement used to quantify the color temperature of light sources. It is the SI unit of thermodynamic temperature and is denoted by the symbol K.

A tea light candle, also known as a tea candle or tea light, is a small cylindrical candle typically encased in a metal or polycarbonate plastic cup.

A smart light switch is a WiFi-enabled device that replaces a traditional light switch in a lighting system. When connected to a home’s wireless network, the smart light switch allows users to remotely control the switch, either through a smartphone app or voice assistants.

Lighting control is the system or technologies that are used to regulate and manipulate the intensity of light and the color temperature in a specific area.

Delivered lumens are the actual amount of useful light that is emitted and reaches a specific area or scene. It takes into account factors such as reflection, refraction, and absorption that can cause some of the light to be lost or redirected within the lighting fixture.

Color Rendering Index (CRI) is a measurement to assess how accurately a light source can reproduce the colors of objects. It is represented on a numerical scale ranging from 0 to 100, with higher values indicating better color rendering capabilities.

Far red light, also known as FR light, is a waveband at the extreme end of the visible light spectrum, with wavelengths between 700 and 780 nanometers (nm).

A pulse start ballast is a type of ballast specifically for pulse start metal halide lamps. Unlike traditional probe start ballasts, pulse start ballasts do not rely on a starting probe electrode.

Instant Start (IS) is a starting method used for fluorescent lamps. It involves the use of electronic ballasts that apply a high voltage directly to the lamp’s electrodes without preheating the cathode.

A wafer light, also known as a canless light, is a type of lighting fixture which is characterized by its ultra-thin design, making it ideal for recessed lighting applications.
