How To Choose The Best Metal Halide

What Is The Purpose Of A Metal Halide Light?

MH lights are commonly used for general lighting purposes because they provide excellent color rendering properties. In addition, they are very efficient and last longer than other types of bulbs.

How Do Metal Halides Compare To Other Types Of Lights?

The main advantage of MH lights compared to other types of bulbs is their efficiency. Because of its higher intensity, MH lights require fewer watts per lumen. For example, a 100W MH lamp uses only 10% more electricity than a 60W incandescent bulb. Another benefit of MH lights is their long lifespan. Most MH lights have lifespans of 25, 000 hours or more.

Benefits Of Using Metal Halide Lamps

There are many benefits associated with using metal halide lamps. One major benefit is the fact that these lamps emit little heat. Unlike CFLs which generate significant amounts of heat, MH lamps create no heat whatsoever. As a result, there is no danger of burning anything around the room. Also, unlike regular incandescent bulbs, MH bulbs do not contain lead. Therefore, children cannot touch them and put them into their mouths. Finally, MH lights are extremely durable. Even though they are expensive, they still last longer than traditional bulbs.

Types Of Metal Halide Bulbs

There are two main types of MH bulbs available: arc tubes and reflector systems. Arc tube MH bulbs consist of a glass envelope filled with argon gas along with mercury and sodium iodide. An electric current passes through the electrodes inside the tube causing the gases to ionize and form plasma. Once formed, the plasma emits ultraviolet radiation. The UV rays excite the mercury atoms resulting in visible blue light.

Reflector systems consist of a parabolic mirror attached to a quartz envelope containing mercury and sodium iodide. The parabola reflects the light emitted by the arc tube onto a diffuser plate where the light radiates outward.

Are There Any Disadvantages Associated With Using Metal Halide Bulbs?

Although MH bulbs are generally considered safe, there are certain precautions that must be taken before purchasing one. First, you should always read the manufacturer's instructions carefully prior to installation. Second, never leave a bulb unattended while operating. Third, avoid placing the bulb near flammable materials. Fourth, follow proper safety procedures when handling the bulb. Fifth, turn off the power supply immediately once the bulb has been removed from the socket. Sixth, store the bulb away from direct sunlight.

The Importance of Purchasing a Quality Metal Halide Bulb

CRI is a measure of the ability of a lighting source to reproduce colors accurately. High-quality metal halide lamps produce more accurate color reproduction than other types of incandescent lights. In addition, these lamps provide greater efficiency than compact fluorescent lamps. Because of their higher efficiency, metal halide lamps consume significantly less electricity than conventional incandescent lamps.

Benefits of Using a Metal Halide Light

There are many benefits associated with using a metal halide lamp. For example, metal halide lamps last longer than traditional incandescent lamps. Additionally, because metal halide lamps operate at lower temperatures, there is no danger of fire. Also, unlike most other types of bulbs, metal halide bulbs do not contain mercury. Mercury has been linked to health problems including brain damage and birth defects. Finally, metal halide bulbs emit very little heat. As a result, they are suitable for areas where heat could be problematic.

How To Choose A Metal Halide Lamp

In order to choose the right metal halide lamp for your needs, you must first determine whether you require a floodlight or spot light. Floodlights illuminate large spaces while spot lights are designed to highlight specific objects. Spot lights are typically smaller than floodlights. If you plan to install a metal halide lamp in a ceiling fixture, you will probably need a floodlight. However, if you intend to mount the lamp directly onto a wall, you will likely need a spot light.

Types of Metal Halide Lamps

There are two main categories of metal halide lamps: linear and reflector. Linear metal halide lamps consist of a single tube containing both the filament and the arc chamber. Reflector metal halide lamps have a parabolic shape and include a reflective coating inside the glass envelope. Both types of metal halide lamps are available in different wattages.


Watts refer to the amount of electrical power required by a given type of bulb. Generally speaking, the higher the wattage rating, the brighter the light output. Most metal halide lamps sold today are rated between 100 watts and 300 watts.

Color Rendering Index Rating

CRI refers to the degree to which a particular light source reproduces true colors. Higher numbers indicate a more faithful representation of actual colors.

Lighting Applications

Metal halide lamps are commonly used in commercial settings such as warehouses, factories, retail stores, restaurants, offices, schools, hospitals, museums, and theaters.

The CRI rating measures how well a lamp renders colors. In general, higher numbers indicate greater accuracy. However, there are many factors that influence the actual CRI rating of a particular lamp. Some manufacturers claim a CRI rating of 100 while others only claim 90. There are several other features to be aware of when purchasing a metal halide lighting fixture.

Color Rendering Index Rating

The CRI rating is measured by comparing the output of the lamp to the output of a reference illuminant. The most common reference illuminants are D65 and D50. Both produce white light which has been standardized to match daylight. If you're using a tungsten filament lamp, the CRI rating will be lower because the tungsten does not emit pure white light.


Most metal halide fixtures operate at around 1000 watts. While this is more power than incandescent lamps, it is still significantly less than fluorescent tubes. Fluorescent lights typically run anywhere from 10, 000 to 20, 000 watts.

Lighting Angle

This refers to the angle at which the light spreads. Metal halide bulbs spread light evenly across a room. Incandescents generally throw light toward the center of the room.

Lamp Life

Metal halides last longer than traditional incandescents. Typically, metal halide bulbs will last 15 years or more. Incandescents typically burn out within 5 years.


Some metal halide bulbs contain mercury. Mercury is toxic so please take care when handling these bulbs. Also, never leave children unattended near these bulbs.

Fixture Size

Metal halide fixtures vary greatly in size. Smaller fixtures are ideal for smaller rooms. Larger fixtures are best suited for larger areas.

Mounting Options

There are two types of mounting options available. One type mounts directly into the ceiling grid. The second type attaches to the wall bracket.

Wall Bracket Mounted Fixtures

These fixtures mount onto a standard 2x4 stud wall bracket. Wall brackets are commonly found in bathrooms and kitchens.

Flush Mounted Fixtures

Flush mounted fixtures attach directly to the floor. Flush mounted fixtures are great for large spaces where ceilings are too low to install a ceiling mounted fixture.


Many metal halide fixtures include dimmable ballasts. Dimming controls allow you to adjust the brightness of the fixture.

Energy Efficiency

Metal halide fixtures are very efficient. Because they use less electricity than incandescents, they require fewer electrical outlets.

Different Types of Metal Halide Bulbs

Metal halides are high-intensity discharge lamps which produce white light. Sodium iodide has two advantages; it increases the amount of visible light produced by the lamp while reducing ultraviolet radiation. In addition, it reduces the amount of heat generated during operation. Metal halide bulbs are available in many different styles including compact fluorescent versions.

Types of Metal Halide Lamps

The main differences between metal halide lamps are the shape of the arc tube and the power rating. There are three main categories of metal halide lamps based on these features.

Tungsten Arc Lamp - Tungsten arc lamps consist of a tungsten filament inside a quartz envelope. The arc tube contains a small quantity of inert gas along with other additives. The arc tube is filled with argon and sealed shut using either glass or ceramic materials. The tungsten filament heats up to very high temperatures causing it to emit electrons. As the electrons travel down the length of the filament, they collide with atoms in the tungsten creating additional free electrons. The combination of the heated tungsten and the free electrons creates an electric current.

Mercury Vapor Lamp - Mercury vapor lamps contain a mixture of mercury and rare gases. Rare gases include neon, xenon, krypton, etc. The mercury vapor lamp produces more blue light than the tungsten arc lamp. However, the mercury vapor lamp does not generate enough UV rays to be considered a good choice for outdoor lighting applications.

Benefits of Using Metal Halide Lights

There are several benefits associated with using metal halide lights. First, they last longer than incandescent bulbs. Second, they require lower operating voltages than traditional incandescents. Third, they consume less electricity than conventional incandescents. Fourth, they are more efficient than standard incandescents. Fifth, they are safer than regular incandescents. Sixth, they are generally brighter than incandescents. Seventh, they are easier to install than incandescents. Eighth, they are cheaper than incandescents. Ninth, they are more durable than incandescents. Tenth, they are more environmentally friendly than incandescents.

How To Choose Metal Halide Lightbulbs

Choosing the right metal halide lightbulb depends largely upon the application. For example, if you plan to hang your light fixture outside, you might choose a low voltage version. If you're going to put your light fixture indoors, you might opt for a higher voltage model.
