Metal Halide Lamp Color

New technologies particularly pulse starting technology now allow users to select among a variety of lamp types to suit a wide range of applications.

Metal halide lamp color.

History of the metal halide lamp. A metal halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides compounds of metals with bromine or iodine it is a type of high intensity discharge hid gas discharge lamp. Metal halide lamps have gone through a number of revolutionary changes and improvements over the last several years. This is why new lamps can sometimes be unstable or vary in color.

Metal halide lamps are one of the fastest growing light sources around the world. They offer high efficacy excellent color rendition long service life and good lumen maintenance. These lamps feature special chemical compounds known as halides that produce light in most regions of the spectrum. However some metal halide bulbs have a high color rendering index of 90.

It is measured on a scale of 1 to 100 with 100 being the highest. Developed in the 1960s they are similar to mercury vapor lamps but contain additional metal halide compounds in the quartz arc tube. As metal halide lamps age chemical changes occur causing. Specialty colors including blue green aqua and pink can also be produced.

Different colors are produced in metal halide lamps by using various arc tube shapes and metal halide salts. In addition cmh lamps feature long lifetimes similar to hps lamps. The special mixture of halides provide all of the color without the use of expensive gels or color filters. Excellent color rendering metal halide offers excellent color rendering with a 65 90 cri color rendering index.

Steinmetz was the first person to take a mercury vapor lamp and use halide salts in an attempt to produce a better light color. In new lamps these halides need to burn in for approximately 100 hours before they reach their optimum color. The latest advancements in ceramic metal halide technology provide lamps with high color temperature cct and a variety of high cri values available for various applications vastly improving visual acuity. Most metal halide lamps have a low color rending index ranging in the 60 to 70 range.

Colorlite metal halide lamps produce saturated colors of blue green magenta and orange. Metal halide lamps are among the most energy efficient sources of white light available today. Designable color metal halide lamps can be designed to produce almost any color temperature desired from 2700k to 20 000k. The basis for the metal halide lamp starts all the way back in 1912.
