Most metal halide lamps have a low color rending index ranging in the 60 to 70 range.
Metal halide lamp color.
Metal halide lamps are one of the fastest growing light sources around the world.
Metal halide lamps that have a high cri include flood lamps used for retail lighting and grow lamps.
Different colors are produced in metal halide lamps by using various arc tube shapes and metal halide salts.
The basis for the metal halide lamp starts all the way back in 1912.
In new lamps these halides need to burn in for approximately 100 hours before they reach their optimum color.
It is measured on a scale of 1 to 100 with 100 being the highest.
Double ended 150w in blue green magenta orange.
In addition cmh lamps feature long lifetimes similar to hps lamps.
Metal halide lamps are among the most energy efficient sources of white light available today.
New technologies particularly pulse starting technology now allow users to select among a variety of lamp types to suit a wide range of applications.
Colorlite metal halide lamps produce saturated colors of blue green magenta and orange.
These lamps feature special chemical compounds known as halides that produce light in most regions of the spectrum.
Steinmetz was the first person to take a mercury vapor lamp and use halide salts in an attempt to produce a better light color.
Specialty colors including blue green aqua and pink can also be produced.
As metal halide lamps age chemical changes occur causing.
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.
Developed in the 1960s they are similar to mercury vapor lamps but contain additional metal halide compounds in the quartz arc tube.
However some metal halide bulbs have a high color rendering index of 90.
A researcher by the name of charles p.
Colorlite lamps can be used with standard metal halide ballasts and fixtures.
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.
Designable color metal halide lamps can be designed to produce almost any color temperature desired from 2700k to 20 000k.
This is why new lamps can sometimes be unstable or vary in color.
