A specular surface is a smooth and mirror-like surface that exhibits specular reflection. Specular reflection is a type of surface reflectance where parallel rays of light bounce off the surface at the same angle, resulting in a clear and focused reflection.

PCB stands for Printed Circuit Board. In the lighting industry, a PCB is used to provide interconnections between electronic components. It is a flat board made of non-conductive material, such as fiberglass or epoxy, with conductive pathways etched or printed on it.

Dimming is the process of adjusting the brightness or intensity of a light source that involves controlling the amount of electrical current supplied to the light source, allowing for changes in the level of illumination.

Candlepower measures the luminous intensity of a light source in a specific direction. It originated from the common and uniform output of light from when the candle was the main source of light.

Three-point lighting is a widely used lighting setup technique in the film, photography, and stage industries. It involves the strategic placement of three distinct light sources to achieve a desired lighting effect on a subject in a scene.

A series circuit is a type of electrical circuit where the components or devices are connected in a continuous row, forming a single path for the current to flow.

Veiling reflections efer to the phenomenon where the contrast between a task and its background is reduced due to the reflection of light rays.

Single ended refers to a specific type of LED lamp or installation method. It describes LED lamps where the live and neutral pins are located on the same side of the lamp, known as the “input” end.

A heat sink is a component used in LED lights to dissipate the heat generated by the LEDs. It is typically a metal block or plate that is strategically placed within the light fixture.

Ceiling cavity is the space formed by the ceiling, the plane of the luminaires, and the wall surfaces between these two planes.
