Light appearance is | 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 cool 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. With the most common gear, an electromagnetic ballast along with an ignitor, flicker is noticeable. | ||
This type of single-ended lamps were used sometimes for lighting exterior areas, especially for higher powered lamps but the most frequent application was indoor accent lighting, especially for lower wattages. The lamp was relatively affordable (for a metal hallide lamp) and very 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. The universal operating position is a major benefit even if the lamp life is relatively short. While warm up time is low, with the lamp achieving high output quite quickly, they are slow to restart, 15 minutes pauses not being uncommon. Only sodium vapour ballasts can be used if provided with a suitable ignitor. | This type of single-ended lamps were used sometimes for lighting exterior areas, especially for higher powered lamps but the most frequent application was indoor accent lighting, especially for lower wattages.
