Lamp Life For Metal Halide

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.

Lamp life for metal halide. However some metal halide bulbs have a high color rendering index of 90. A halide is a chemical compound of a halogen combined with an electropositive element or in the case of lamps. A halogen is a monovalent element which readily forms negative ions. The average life is determined when 50 of traditional metal halide lamps initially installed are still operating.

So in keeping in the characteristics of metal halide they would produce the light output of a 400 wmh lamp in roughly 5 000 to 6 000 hours of use.

Most metal halide lamps have a low color rending index ranging in the 60 to 70 range. However larger lamps like 1000 watt metal halides have a lower life expectancy approximately 15 000 hours.

1000wmh lamps are rated for a life of around 11 000 hours. So in keeping in the characteristics of metal halide they would produce the light output of a 400 wmh lamp in roughly 5 000 to 6 000 hours of use. The average life expectancy of metal halide lamps is 20 000 hours. 1000 watt metal halide lose 50 even faster 1000w mh lamps are rated for a life of around 11 000 hours.

It is measured on a scale of 1 to 100 with 100 being the highest. When it comes to led lighting manufacturers use the l70 rating to define the life expectancy of their products. 1 how it works. 200w led corn light bulb e39 mogul base 5000k daylight 26000lm 1000 1200watt cfl hps metal halide equivalent outdoor large area lamp replacement for street garage warehouse high bay cob lighting 4 5 out of 5 stars 23.

Metal halide lamps that have a high cri include flood lamps used for retail lighting and grow lamps. 1000 watt metal halide lose 50 even faster. The lamp uses mercury vapor to create the powerful light like the high pressure mercury vapor but includes other metals halide salts to improve the color. A metal halide lamp or light fixture offers lighting with a high lumen output and life expectancy of 15 000 hours.

Rated or average median life for metal halide lamps is a value of lamp life expectancy based on laboratory and field tests of representative lamps operating on approved ballasts with a burn cycle of at least 10 hours per start.
