The metal halide high bay or lower bay light is no longer working. Here certainly are a few recommendations to troubleshoot your metal halide:

a) Assure voltage is current at fixture by studying which has a voltage meter.
b) If there is voltage, make sure the wires are effectively wired to your proper voltage. In our metal halide high bay and lower bay lights, multi tap ballasts permit for that lights to get wired for 120, 208, 240, or 277 volts.

c) Assuming the very first two methods are satisfactory, it truly is time to check the light bulb. The most typical strategy to test a light bulb would be to try out your bulb inside a operating light fixture to make sure it operates properly.you will discover two kinds:metal halide lamp and high pressure sodium lamps.
Metal halide lighting differs from High Pressure Sodium (HPS) while in the shade and quality of light delivered. Metal halide is really a very effective light source capable of delivering a white light from the array of 2700 to 5500 Kelvin with normal CRIs while in the mid-60s to mid-70s. Some lamp chemistries even get CRIs during the 80s. In contrast, high pressure sodium lamps yield yellow lighting (2200K) and also have a very bad shade rendering index of 22.

HPS lamps are available in color-corrected versions that shorten their existence and only slightly increase color temperature. Even with enormously enhanced CRIs, the color temperature nonetheless delivers yellow light. This colour limitation is present due to the fact the HPS lamp generates light through the excitation of sodium. Metal halide lamps, on the other hand, create light as a result of the excitation of 2 to five various chemical compounds within the arc tube. On top of that, the unique Uni-Form formed physique arc tube can be a newly-designed, compact light source sculpted to observe the bodily form from the arc itself. The precise geometry of this distinctive arc tube, accurately reproducible from lamp to lamp, generates a metal halide lamp of higher efficiency, improved colour uniformity, and longer life.

At last, the over three actions are satisfactory, your problem is most likely together with the ballast and/or capacitor. We recommend putting in a fresh ballast kit.
