Marked with best advantages of energy effectiveness, affordable, long life, clear white light and high color rendering capabilities, the metal halide wall packs are one of the many High Intensity Discharge or HID illumination fixtures. Most industrial and business production units prefer installing metal halide high bays and wallpacks due to the excellent color rendering and uniform brightness which is essential for assembly work in factories while the illumination without high glare is important for the safety of the workers.
The long life of the metal halide lamps along with low maintenance and replacement is one of the major reasons that it is preferred choice in lamps. And the metal halide lamps are not restricted to wallpacks but most of the industrial and business production units use high bay light fixtures. Most of the high bay lights are used in docks, ceilings of the warehouses and industrial units. But the best aspect of using metal halide wallpacks is that there are no replacements that are required on a regular basis but offers long term working of the wallpacks.
Usually none of the wallpacks and light fixtures using metal halide require replacements so the industrial unit or business saves money on the replacement costs. With durable polycarbonate covering, power cables and lamp fitted within the secure aluminum casing, wallpacks are protected from winds, extreme temperatures and dust. The change over to different and innovative technology oriented lighting is due to the energy efficient lighting provided by the metal halide lamps. This ensures a large cut in the energy bills and with no maintenance that is required, replacement costs are reduced.
The CRI of metal halide lamps is 65 to nearly 95 on an average depending upon the wattage. However, all of the metal halide lamps have intense brightness and the CRI depends upon the ballast control, wattage, position of the wallpack. On comparing the illumination lumens per wattage of metal halide to CFL and mercury vapor, the difference in light intensity is visible.
With constant technological innovations that have been evolving over the years, the latest offering of pulse-start metal halide wallpacks has enhanced the chances of lower costs of energy consumption. It is best for designers and contractors to talk to the consumers about the benefits of quick start pulse-start MH technology and how it can effectively cut electricity bills every month.
Most of the metal halide bulbs used to take about 2 minutes to resume illumination due to the slow arc lighting but with the quick action striking within the arc, the power comes on instantly. The illumination has remained constant while the watts required have gone down considerably.
