Mercury vapour lamps were traditionally used on industrial and street lighting and they can be used on these areas although LED lamps offer much better performance with lower energy consumption. There are still some specific uses that are specific to this technology. Light appearance is cool white with a bias towards reds as well as blues, and, especially ultraviolet. | |||
Although this is rarely specified or even mentioned in datasheets, UV-A emission is significant if the lamp is used as is, with no cover. This means that most surfaces that are painted white look even whiter in this light. Trees foliage is also emphasized, so this type of lamps are very well suited in gardens. Flowers are not as well showcased as some colours are missing except for red, orange, white, blue and violet. | |||
Houses can be properly light but such a lamp is less suited for living rooms, bedrooms but is well suited for workshops, halls or any other space that requires wide area lighting. Generally, low power lamps such as 50W are to be avoided as they are quite fragile so typical applications focus on 125 and 250 watt lamps and 400, 700, 1000W lamps are typically too large or cumbersome to be used as free standing lamps or in light fixtures. Due to the fact that fixtures are getting harder to find, outside applications such as area lighting should consider a minimal protection for lamps, meaning that floodlighting is harder than in the past. Of course, any metal-hallide and high pressure sodium fixture can be adapted, if found. | |||
