LM-70, also known as Illuminating Engineering Society Standard LM-80-08, is a lingo used in the lighting industry to refer to a standardized method for measuring lumen maintenance of LED light sources.

Photometric is the study and measurement of light distribution from lighting fixtures. It involves analyzing how light illuminates a specific area or space, allowing light designers to assess lighting levels and characteristics.

An incandescent light, also known as an incandescent bulb or lamp, is a type of electric light source that produces light through the process of incandescence.

A chrome cap is a specific type of center cap designed for 57DR and 57CR Gram Light wheels. These center caps are made of plastic but feature a finish that closely resembles anodized aluminum.

Passive infrared detection, also known as PIR detection, is a method of motion detection based on changes in infrared radiation. PIR sensors, which are commonly used in lighting systems, detect the infrared radiation emitted by or reflected from objects in their field of view.

Mean Lumens, also known as design lumens, is a term used to describe the average light output produced by a lamp throughout its rated life.

A PN junction is a fundamental component, specifically in the operation of LED lights. It refers to the junction formed between a P-type semiconductor and an N-type semiconductor.

A wall sconce is a type of lighting fixture that is mounted on a wall rather than hanging from a ceiling.

A joule is a unit of measurement for energy in the International System of Units (SI). It is used to quantify the amount of energy released or transferred over a period of time.

An A19 bulb is a specific type of light bulb commonly used in the lighting industry. The term “A19” refers to the bulb’s size and shape.
