Mercury vapor lamp

Online For Delivery Or Collection. A mercury - vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small. Introduction: The mercury vapor lamp is a high intensity discharge lamp. It uses an arc through vaporized mercury in a high pressure tube to create.

High pressure mercury - vapor lamps are the oldest high pressure lamp type and have been replaced in most applications by metal halide and the high pressure sodium lamps. They require a shorter arc length. In case of fluorescent lamp the mercury vapour pressure is maintained at lower level such that of the total input energy gets converted into 253.

The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering. A mercury-vapor lamp is a gas discharge lamp which uses mercury in an excited state to produce light. It makes light by a spark in a tube that contains mercury.

The spark makes the mercury atoms release ultraviolet and visible.

The ballast sends electrical power to the electrodes, which excites the gas and makes it glow. The protective bulb filters out harmful ultraviolet light and keeps the mercury gas contained if the inner chamber breaks. The outer bulb can also be coated with phosphor to diffuse the light.

Medium-pressure lamps draw a much greater current than low-pressure lamps, leading to a rapid rise in the mercury vapor pressure. This gives a typical diffuse medium. Before there were metal halide lamps, there was the mercury vapor lamp. In fact, the mercury vapor lamp is considered the first type of.

A mercury-vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light. Mercury-vapor lamp electric lighting source. Mercury vapour pressure is typically around ten atmospheres. Free Shipping on Orders Over £45!

The reason for the creation of this second category of mercury lamp was to allow the efficacy to be maintained as high as possible for low wattage sources. Mercury-vapor lamp definition is - an electric lamp in which the discharge takes place through mercury vapor —called also mercury lamp. The bulbs have an inner quartz tube. A lamp in which ultraviolet and yellowish-green to blue visible light is produced by an electric discharge through mercury vapor. The color spectrum may be corrected.

A vapor lamp consists of a double tube. The vapor is contained in the internal tube, while the outer tube is kept empty of air, and absorbs dangerous high-energy ultraviolet radiation.

Mercury Vapor lamps feature low initial cost, but have higher operating costs than HPS or Metal Halide due to its lower efficiency. Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level.
