A 5mm is a mini LED bulb usually features a wide-angle, concave lens that measures roughly 5 millimeters in diameter. The lens concentrates the light from the miniature bulb and helps to evenly distribute it in a wider range than…

A wire nut is an electrical connector used to fasten two or more wires together. They are made from plastic and are designed to securely hold the multiple single-strands of wire in place, preventing them from coming into contact with…

Wattage is a measure of electrical power, expressed in watts. It’s the product of one ampere (1A) of current multiplied by one volt (1V) across an electrical circuit, and is used to calculate the total amount of energy being supplied…

A watt is the SI unit of power, which measures the rate of energy conversion. It’s equal to one joule (1J) per second, or it can be defined as the amount of power used by an electric circuit when one…

Wall washing is a lighting technique that uses fixtures to project light over a large surface area with even brightness. It’s often used in outdoor environments such as walkways, building facades and driveways to evenly illuminate large areas while maintaining…

Wall grazing is a lighting technique that uses light fixtures to graze surfaces of vertical walls in order to produce a dramatic effect. It’s an effective method for accentuating architectural features and drawing attention towards artwork, sculptures or other objects…

Voltage, also known as electrical potential difference or potential difference, is an electrical quantity that measures the potential energy per unit charge in an electrical circuit. Voltage can be measured using a voltmeter and is expressed in volts (V).

Usable Light Hours, also referred to as photosynthetically active radiation (PAR), is the amount of light that is available for a photo-synthesizing organism such as a plant to absorb and use. PAR ranges from 400-700 nanometers (nm) in wavelength, which…

Underwriters Laboratories (UL) is an independent, not-for-profit organization who tests and certifies products and materials for safety. Founded in 1894 in the United States, UL is now operating in over 104 countries worldwide providing product safety assurance services to manufacturers…

Ultraviolet (UV) radiation is a type of electromagnetic radiation that falls within the spectrum of light just beyond visible light. It has wavelengths shorter than visible light but longer than X-rays and gamma rays, which makes it invisible to the…

Transparent is a term that describes the degree to which light passes through an object without being scattered. In other words, a transparent material will allow all or almost all of the incident light to travel directly through it. This…

Translucent is a term that describes the degree to which light is able to pass through an object. It can be thought of as a measure of translucency, or the amount materials allow light to come through them in differing…
