Can metal halide bulbs explode?

Can metal halide bulbs explode?

Metal halide (MH) lamps can explode (typically referred to as sudden nonpassive failure) because they operate at high pressures, but some products are manufactured with safety features to prevent injury.

What are the characteristics of metal halide lamps?

Characteristics

  • Characteristics.
  • The unique characteristics of metal halide lighting provide high performance such as: Long Life.
  • Better Light Quality.
  • Designable Color.
  • Excellent Color Rendering.
  • Compact Size.
  • Versatility.
  • High Efficiency.

Why is my metal halide bulb flickering?

With mercury lamps, improper ballasting can cause flickering or erratic operation. With metal halide lamps, the effect is generally noticed in the startup period when the lamp ignites, starts to warm up and then extinguishes (cycling). This may be caused by improper voltage/current relationships delivered by ballast.

What color is metal halide light?

white light
Metal halide lamps generate a very cool white light. They are available in color temperatures as low as 3000K. Some metal halides are available with extremely cool color temperatures up to 20,000K.

Are metal halide bulbs safe?

Broken and unshielded high intensity metal halide and mercury vapor light bulbs continue to cause eye and skin injuries, particularly in school gymnasiums.

Are metal halide bulbs toxic?

Exposure to broken metal halide bulbs can result in skin and eye irritation, including photokeratitis, particularly in settings such as sports facilities where balls or other objects are routinely thrown.

How hot do metal halide bulbs get?

When fully lit, the Metal Halide lamp will reach a temperature of 2000 degrees Fahrenheit and operates at a vapour pressure between 70 and 90 pounds per square inch. Normal use of Metal Halide lighting requires that they are very rarely, if ever shut off.

How can you tell if a metal halide bulb is bad?

Usually the lamps will gain a pinkish hue when compared to other lamps in the same system. This is caused when metal vapors in the lamp are expired from heat or burning, and the lack of a particular mixture in the arc tube renders a different color.

How can you tell the difference between an HPS and an MH bulb?

What is the Difference Between Metal Halide and High Pressure Sodium? Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange.

Can metal halide (MH) lamps explode?

Metal halide (MH) lamps can explode (typically referred to as sudden nonpassive failure) because they operate at high pressures, but some products are manufactured with safety features to prevent injury. For example, many luminaires include a tempered-glass or acrylic enclosure to contain any debris in the event of explosion.

What are metal halide lights and how do they work?

Metal Halide Lights: What are they and how do they work? Since the 1960s, the metal halide (MH) lamp has been a used as a viable light source for a number of applications, from illuminating sports fields, to parking lots and street lighting, to general indoor lighting for retail stores and factories.

What is the color temperature of a metal halide lamp?

With the introduction of specialized metal-halide mixtures, metal-halide lamps are now available with a correlated color temperature from 3,000 K to over 20,000 K. Color temperature can vary slightly from lamp to lamp, and this effect is noticeable in places where many lamps are used.

What gases are in a metal halide lamp?

With a metal halide lamp, that mix of gases will normally include mercury, xenon or argon, and a variety of metal halides. Metal halides are produced as a result of combining halogen with a metal. In metal halide lamps, that is normally metals that have been mixed with iodine or bromine.
