Metal Hallide lamps are still widely used on commercial, industrial and architectural lighting but in these applications LED lamps are quickly replacing them due to much better performance, lower energy consumption and easy servicing. Light appearance is coll white or daylight, depending on lamp model, with good colour reproduction and low ultraviolet emission. The lamp can be used indoors as well as outdoors, when intense lighting is required as most surrounding look quite pleasing being light with new lamps. | Metal Hallide lamps are still widely used on commercial, industrial and architectural lighting but in these applications LED lamps are quickly replacing them due to much better performance, lower energy consumption and easy servicing.

With the most common gear, an electromagnetic ballast along with an ignitor, flicker is noticeable. | ||
These type of double-ended lamps were used sometimes for lighting exterior areas, especially for higher powered lamps but the most frequent application was indoor accent lighting with lower wattages. The lamp was relatively affordable (for a metal hallide lamp) and compact, having a successful niche until LED lamps appeared. Since they are very compact light sources it should be noted that heat output is very high, making the lamp unsuitable for open-air operation, seriously limiting flexibility. Another very important limitation is caused by the mandatory operating position and relatively short lamp life. While lamp warm up time is low, with the lamp achieving high output quite quickly, they are slow to restart, 10 minutes pauses not being uncommon. Both high pressure mercury vapour as well as sodium vapour ballasts can be used if provided with a suitable ignitor. | These type of double-ended lamps were used sometimes for lighting exterior areas, especially for higher powered lamps but the most frequent application was indoor accent lighting with lower wattages.
