Mercury Lamps: A Comprehensive Guide

With so many energy efficient light bulbs on the market, it can be extremely difficult choosing one to suit your needs. Now BLT Direct, the leading suppliers of light bulbs, light fittings and low energy light bulbs, are offering sound yet practical advice on one of lightings most popular bulbs- The mercury lamp, Also known as the mercury vapour lamp, this efficient lamp, uses mercury in an excited state to produce light. Usually confined to a small fused quartz arc tube mounted inside a glass bulb, this efficient light source can be either clear or coated in phosphor.

When a mercury lamp is first turned on, it produces a dark blue light partly down to the fact that only a small amount of mercury is ionized and the pressure in the arc tube is kept to a minimum level, usually inside the ultraviolet mercury bands. Once the gas has been left to heat up, it causes the mercury emission bands to broaden and the final effect is that the light produced is much whiter.

Offering the user with a long lasting solution to their lighting requirements, and an intense light, mercury lamp is suitable for a number of applications including office lighting, lighting for public places, lighting for outdoor use or even for use in floodlights.

Boasting benefits such as consistent quality, a low purchase price and maintenance fee, being easy to install and offering consistency of colour, there really is no reason to go back to the traditional light bulb.

Whether you require self-ballasted or blacklight lamps, BLT Direct have something to suit every need and budget requirement.
