Whois & Analysis for topbulb.com

An electric light is a device that produces visible light by the flow of electric current.

It is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities.

In technical usage, a replaceable component that produces light from electricity is called a lamp.

Compact lamps are commonly called light bulbs; for example, the incandescent light bulb.

Lamps usually have a base made of ceramic, metal, glass or plastic, which secures the lamp in the socket of a light fixture.

The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a bayonet cap.

An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire heated to such a high temperature that it glows with visible light (incandescence).

The filament, heated by passing an electric current through it, is protected from oxidation with a glass or quartz bulb that is filled with inert gas or evacuated.

In a halogen lamp, filament evaporation is prevented by a chemical process that redeposits metal vapor onto the filament, extending its life.

The light bulb is supplied with electric current by feed-through terminals or wires embedded in the glass.

Most bulbs are used in a socket which provides mechanical support and electrical connections.

The stock (also capital stock) of a corporation is constituted of the equity stock of its owners.

A single share of the stock represents fractional ownership of the corporation in proportion to the total number of shares.

In liquidation, the stock represents the residual assets of the company that would be due to stockholders after discharge of all senior claims such as secured and unsecured debt.

Stockholders' equity cannot be withdrawn from the company in a way that is intended to be detrimental to the company's creditors.

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect.

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.
