Metal Halide Uv Lamp Spectrum

Developed in the 1960s they are similar to mercury vapor lamps but contain additional metal halide compounds in the quartz arc tube.

Metal halide uv lamp spectrum. But since the salts inside a cmh are able to heat up to much a high temperature they re actually turned into what resembles plasma. Cmh grow lights provide uv ultra violet radiation which although being outside of our range of vision is beneficial at certain ranges and intensities to plant growth and development. An electrical current vaporizes the mercury and creates spikes of light mostly in the uv. As the high temperature of the arc discharge excites the halogenides to evaporate and separate into atoms the metallic atoms illuminate and release the predetermined target ultraviolet wavelength.

Ushio mhl series metal halide lamps contain mercury scandium and various other metal halogens in an inner bulb that produces a very high light output. The reef brite twin arc metal halide lamp is one of the most exciting new developments in aquarium lighting in almost a decade. Most ceramic metal halide lamps were designed for use in the retail space so the uv light was blocked. Some manufacturers mix the metal halide technology with others to improve light output and add a few variations into the color spectrum for a more complete solution.

Usually they re rated with a high lumen output of around 100 lm per watt a lamp life of up to 20 000 hours and pretty decent degradation rates. When the mercury arc is struck the heat vaporizes the metal halides and this process broadens the spectrum of light produced. In 1860 john thomas way used arc lamps operated in a mixture of air and mercury vapor at atmospheric pressure for lighting. There are salts inside of the arc tube that heat up to a high temperature and that give off a certain spectrum.

They produce uv a uv b and uv c light but uv c is generally very harmful to human eyes. 11 8 3 metal halide light sources. Hortilux uses a glass that allows the uv light to pass through benefiting plant growth. 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 are quartz tubes filled with trace amounts of mercury and metal halide salts. The eye hortilux cmh 315 grow lamp was designed specifically for horticulture. Charles wheatstone observed the spectrum of an electric discharge in mercury vapor in 1835 and noted the ultraviolet lines in that spectrum. Cmh lamps burn just like a normal metal halide lamp.
