Lamps & Lightbulbs

Lamps are a device for giving light, either one consisting of an electric bulb together with its holder and shade or cover, or one burning gas or a liquid fuel and consisting of a wick or mantle and a glass shade. A light bulb is a glass bulb that is inserted into a lamp or a socket in a ceiling, which provides light by passing an electric current through a filament or a pocket of inert gas.

Compact Fluorescent CFL Lamps
A Compact Fluorescent CFL lamp can be described as a compact fluorescent light that is an energy-saving light and a compact fluorescent tube. It is a fluorescent lamp that is designed to replace an incandescent lamp. Some types fit into light fixtures that were formerly used for incandescent lamps. These types of lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.

Fluorescent Lamps
Fluorescent lamps or fluorescent tubes are low-pressure, mercury-vapor, gas-discharge lamps that use fluorescence to produce visible light. There is an electric current in the gas that excites mercury vapor, which produces short-wave ultraviolet light. This causes a phosphor coating on the inside of the lamp to glow.

Halogen Lamps
Halogen light bulbs or lamps are a type of incandescent lamp. They use a halogen gas that increases both light output and rated life. They are used for moderately high efficiency, quality of light, and high rated life compare to regular incandescent lamps.

High Pressure Sodium Lamp HID
High Pressure Sodium lamps work by creating an electric arc through vaporized sodium metal. Other materials and gases are used to help start the lamps or control its color. High-pressure lamps are efficient lamps and are very powerful lamps for the use of large areas. There is a warm up time of 5 to 10 minutes when it restarts immediately if there is a brownout and the lumen output does not drop with age.

Incandescent Lamps
Incandescent Lamps are an electric light that has a wire filament that is heated to a high temperature by passing an electric current through it until it glows with a visible light. The hot filament is protected from oxidation with a glass or quartz bulb that is filled with inert gas or evacuated. A chemical process redeposits metal vapor onto the filament, extending its life and preventing the filament evaporation.

LED Lamps
LED Lamps are “directional” light sources. This means that they can emit light in a specific direction. LED Lamps are unlike incandescent and compact fluorescent bulbs. These can emit light and heat in all directions. LED lighting is able to use light and energy more efficiently in many applications.

Metal Halide Lamp HID
A Metal Halide lamp is an electric lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides, which are compounds of metals with bromine or iodine. It is a type of high-intensity discharge (HID) gas discharge lamp.

Miniature Lamp
Miniature Lamps are by definition generally small in size and used for task or indicator lighting. A number between one and four digits generally identifies them. They may or may not include letters. Some examples are flashlight bulbs, car indicator lights, landscape lights and appliance bulbs.
