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.

Solid state refers to electronic components, devices, and systems that are based entirely on semiconductor materials, such as silicon, germanium, or gallium arsenide.

Operating position is the specific orientation or position in which a lamp or light bulb is intended to be operated for optimal performance and longevity.

Ordinances (municipal) refers to regulations or rules implemented by a municipality (local government) regarding outdoor lighting practices. These ordinances are used to control and ensure the quality of lighting within the municipality.

LM-80 is a standardized method that evaluates the lumen depreciation of solid-state light sources, specifically LED packages, modules, and arrays. Developed by the Illuminating Engineering Society of North America (IESNA), LM-80 provides a consistent methodology for assessing and comparing the lumen maintenance of LED components from different manufacturers.Maybe You Are In

Driver rating is a metric used to assess the quality and performance of LED drivers. LED drivers are important in regulating the electricity supplied to LED strip lights, converting the alternating current (AC) from the mains to a lower, direct current (DC) voltage required by the LEDs.
