LM-79 is a testing method and data used in the lighting industry to evaluate the performance of LED luminaires. It is an approved method established by the Illuminating Engineering Society of North America (IESNA) for the Electrical and Photometric Measurements of Solid-State Lighting.

Candela (symbol: cd) is a unit of measurement used in the lighting industry to quantify luminous intensity. It represents the amount of light emitted by a light source in a specific direction.

An Edison bulb, also known as an Antique Bulb or Vintage Bulb, is a type of light bulb that replicates the look and feel of the original coiled filament bulbs created by the Edison Electric Light Company in the early 20th century.

The International Electrotechnical Commission (IEC) is a global organization founded in 1906 that focuses on the development and publication of international standards for electrical, electronic, and related technologies.

Lux is a standardized unit of measurement used to quantify the intensity of light level. It’s the unit of illuminance. It represents the amount of light that falls on a specific surface area.

A luminous ceiling is a design element in the lighting industry that involves the use of a specially designed ceiling surface that emits light.

An Ampere, commonly referred to as an amp, is a fundamental unit of measurement used to quantify the flow of electrical current.

Lighting design lumens(LDL) is the number of lumens emitted by a light source after it has been in operation for 2,000 hours.

In a light bulb, a socket is a device specifically designed to securely hold an electric light bulb and establish an electrical connection with circuit wires.

Die-Cast is a manufacturing process used to create LED light fixtures. This process, known as die casting, involves the use of copper, zinc, or aluminum alloys to produce fixtures with excellent dimensional accuracy and minimal additional machining requirements.
