Best Answer

An HQI metal halide lamp belongs to the family of metal halide HID lamps. Hydrargyum quartz iodide (HQI) lamps differ from standard metal halide lamps in that they are often smaller and are offered in double ended versions and require a special socket. The gasses and metal halide salts used in HQI and standard metal halide lamps are the same.

Which light is brighter Metal Halide or mercury Vapor?

Metal Halide lights are generally brighter than mercury vapor lights. Metal halide lights produce a higher quality and more natural light, making them a popular choice for outdoor lighting in stadiums, parking lots, and other large commercial spaces. Mercury vapor lights tend to have a bluish-green tint and are less bright compared to metal halide lights.


Can A 70 watt metal halide bulb be replaced with A 150 watt halide bulb?

No. A 70 Watt metal halide bulb can not be replaced with a 150 Watt halide bulb.


What are advantages of ed28 metal halide lamp over a ed37 metal halide lamp?

The ed28 metal halide lamp typically has a smaller size and lighter weight compared to the ed37 metal halide lamp, making it more suitable for fixtures with space constraints. Additionally, the ed28 lamp may provide more focused light output due to its smaller diameter, which can result in better light distribution and efficiency in certain applications.


Why does metal halide light flicker?

Metal halide lights can flicker due to a variety of reasons, such as a failing ballast, loose electrical connections, or improper voltage supply. These issues can lead to fluctuations in the electrical current, causing the light to flicker. Regular maintenance and proper installation can help prevent flickering in metal halide lights.


How does a metal halide ballast work?

A metal halide ballast works just by transforming the line voltage into much more useful voltage to the metal halide, and by regulating the current so that the bulb will have its useful life at the most.


Will a hps luminaire run a metal halide lamp?

Yes the ballast and starter are the same you can run halide in hps, but not hps in halide.


When A halogen reacts with the metal what is formed?

When a halogen reacts with a metal, an ionic compound called a metal halide is formed. This compound is formed by the transfer of electrons from the metal to the halogen, resulting in the formation of a positively charged metal ion and a negatively charged halide ion. The exact formula of the metal halide depends on the specific metal and halogen involved in the reaction.


Can you use a 400W high pressure sodium bulb in a metal halide ballast?

No, the ballast has to be matched to the lamp. 250 watt ballast, 250 watt lamp. Also be sure to match the lamp type to the proper ballast even though the wattage is the same. HPS ballast to HPS lamp, Metal halide ballast to metal halide lamp and mercury vapour lamp to mercury vapour ballast.


Can you use 250W metal halide bulb in a 1000W metal halide ballast?

No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.


Does a metal halide and mercury vapor use the same ballast?

No, metal halide and mercury vapor lamps do not use the same ballast. Metal halide lamps require a ballast specifically designed for metal halide lamps, while mercury vapor lamps require a ballast designed for mercury vapor lamps. Using the wrong ballast can result in poor performance and potential safety hazards.
