Metal Halide Lamps

Metal halide lamps consist of the following main components. They have metal base (in some cases they are double-ended) that allows an electrical connection. They are covered with an outer glass shield (or glass bulb) to protect the inner components and provide a shield to UV light generated by the mercury vapor. Inside the glass shield, a series of support and lead wires hold the electrodes and the inner "arc tube". It is within the arc tube that the light is actually created. Some bulbs have a phosphor coating on the inner side of the outer bulb to diffuse the light.

Metal halide lamps were initially preferred to mercury vapor lamps in instances where natural light was desired because of the whiter light generated (mercury vapor lamps generating light that was much bluer). However the distinction today is not as great. Some metal halide lamps can deliver very clean "white" light that has a color-rendering index (CRI) in the 80's. With the introduction of specialized metal halide mixtures, metal halide lamps are now available that can have a color temperature as low as 3000K (very yellow) to 20,000K (very blue). Some specialized lamps have been created specifically for the spectral absorption needs of plants (hydroponics and indoor gardening) or animals (indoor aquariums). Perhaps the most important point to keep in mind is that, due to tolerances in the manufacturing process, color temperature can vary slightly from lamp to lamp, and the color properties of metal halide bulbs cannot be predicted with 100% accuracy. Moreover, color properties can change over the lifetime of the bulb.
