Progress Lighting Legend Collection Nine-Light, Two-Tier Chandelier

A chandelier () is an ornamental lighting device, typically with spreading branched supports for multiple lights, designed to be hung from the ceiling. Chandeliers are often ornate, and they were originally designed to hold candles, but now incandescent light bulbs are commonly used, as well as fluorescent lamps and LEDs.

A wide variety of materials ranging from wood and earthenware to silver and gold can be used to make chandeliers. Brass is one of the most popular with Dutch or Flemish brass chandeliers being the best-known, but glass is the material most commonly associated with chandeliers. True glass chandeliers were first developed in Italy, England, France, and Bohemia in the 18th century. Classic glass and crystal chandeliers have arrays of hanging "crystal" prisms to illuminate a room with refracted light. Contemporary chandeliers may assume a more minimalist design, and they may illuminate a room with direct light from the lamps or are equipped with translucent glass shades covering each lamp. Chandeliers produced nowadays can assume a wide variety of styles that span modernized and traditional designs or a combination of both.

Although chandeliers have been called candelabras, chandeliers can be distinguished from candelabras which are designed to stand on tables or the floor, while chandeliers are hung from the ceiling. They are also distinct from pendant lights, as they usually consist of multiple lamps and hang in branched frames, whereas pendant lights hang from a single cord and only contain one or two lamps with few decorative elements. Due to their size, they are often installed in large hallways and staircases, living rooms, lounges, and dining rooms, often as focus of the room. Small chandeliers can be installed in smaller spaces such as bedrooms or small living spaces, while large chandeliers are typically installed in the grand rooms of buildings such as halls and lobbies, or in religious buildings such as churches, synagogues or mosques.

A legend is a genre of folklore that consists of a narrative featuring human actions, believed or perceived to have taken place in human history. Narratives in this genre may demonstrate human values, and possess certain qualities that give the tale verisimilitude. Legend, for its active and passive participants, may include miracles. Legends may be transformed over time to keep them fresh and vital.

Many legends operate within the realm of uncertainty, never being entirely believed by the participants, but also never being resolutely doubted. Legends are sometimes distinguished from myths in that they concern human beings as the main characters and do not necessarily have supernatural origins, and sometimes in that they have some sort of historical basis whereas myths generally do not. The Brothers Grimm defined legend as "folktale historically grounded". A by-product of the "concern with human beings" is the long list of legendary creatures, leaving no "resolute doubt" that legends are "historically grounded."

A modern folklorist's professional definition of legend was proposed by Timothy R. Tangherlini in 1990:

Legend, typically, is a short (mono-) episodic, traditional, highly ecotypified historicized narrative performed in a conversational mode, reflecting on a psychological level a symbolic representation of folk belief and collective experiences and serving as a reaffirmation of commonly held values of the group to whose tradition it belongs.

Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively optical radiation.

In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization. Its speed in vacuum, 299792458 m/s, is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particles. The study of light, known as optics, is an important research area in modern physics.

The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight.

Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

Indoor lighting is usually accomplished using light fixtures, and is a key part of interior design. Lighting can also be an intrinsic component of landscape projects.

Progress is movement towards a perceived refined, improved, or otherwise desired state. It is central to the philosophy of progressivism, which interprets progress as the set of advancements in technology, science, and social organization efficiency – the latter being generally achieved through direct societal action, as in social enterprise or through activism, but being also attainable through natural sociocultural evolution – that progressivism holds all human societies should strive towards.

The concept of progress was introduced in the early-19th-century social theories, especially social evolution as described by Auguste Comte and Herbert Spencer. It was present in the Enlightenment's philosophies of history. As a goal, social progress has been advocated by varying realms of political ideologies with different theories on how it is to be achieved.
