From 20,000 to 23,000 lumens depending on the brand.
Average figures:
Incandescent: 10 lumens per watt
Halogen 13 lumens per watt
CFL (low-energy) 50 lumens per watt
Typical LOR (lumen output ratio) of a reasonable MH downlight would be around 0.6 meaning that you get 60% of the lumen output of the lamp out of the fitting. Any manufacturer should be able to provide the LOR for a particular fitting
No, it is not recommended to use a 70 watt metal halide lamp with a 150 watt ballast. The lamp and ballast wattage should match to ensure proper operation and to prevent damage to the lamp or ballast. It is best to use a compatible lamp and ballast with matching wattages.
A pulse start lamp can work with a metal halide ballast, but compatibility depends on the specific ballast and lamp type. It's essential to ensure that the ballast is rated for pulse start lamps, as not all metal halide ballasts are designed for this purpose. If the ballast is compatible, the pulse start lamp can provide improved efficiency and better performance compared to standard metal halide lamps. Always consult the manufacturer's specifications for optimal results.
There really are no advantages of an ED28 over an ED37. If they are both metal halide lamps then the only difference between them, provided they have the same wattage and color temperature, is that they have different dimensions and different size bases. They will require different size sockets and will likely require different ballasts.
Metal halide ballasts are designed for standard metal halide lamps and may not work properly with pulse start lamps, which require a different starting method. Pulse start lamps typically need a specific type of ballast that provides a higher starting voltage to ignite the lamp. Using a standard metal halide ballast could result in insufficient performance or even damage to the lamp. Always check compatibility with the manufacturer's specifications before use.
A 100-watt metal halide lamp typically produces around 8,000 to 10,000 lumens, depending on the specific design and efficiency of the bulb. This lumen output can vary based on factors such as the manufacturer and the lamp's age. Metal halide lamps are known for their bright, white light, making them popular for outdoor and commercial lighting applications.
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.
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.
Typical LOR (lumen output ratio) of a reasonable MH downlight would be around 0.6 meaning that you get 60% of the lumen output of the lamp out of the fitting. Any manufacturer should be able to provide the LOR for a particular fitting
No. The lamp has to match the ballast. The lamp will not ignite if the wrong ballast is used.
Yes, you can replace a 100-watt metal halide lamp with a 70-watt metal halide lamp, but it will result in lower light output. The 70-watt lamp will provide less brightness, which may not be suitable for applications requiring high illumination levels. Additionally, ensure that the fixture is compatible with the lower wattage to avoid any electrical issues.
The luminous output of a 400-watt metal halide lamp typically ranges from about 30,000 to 40,000 lumens, depending on the specific design and efficiency of the bulb. To convert lumens to lux, you need to consider the area over which the light is distributed. For example, if the light is spread over an area of 10 square meters, the illuminance would be approximately 3,000 to 4,000 lux.
6000lm
Yes the ballast and starter are the same you can run halide in hps, but not hps in halide.
No, it is not recommended to use a 70 watt metal halide lamp with a 150 watt ballast. The lamp and ballast wattage should match to ensure proper operation and to prevent damage to the lamp or ballast. It is best to use a compatible lamp and ballast with matching wattages.
A metal halide lamp's Harmonized Tariff number would fall in the category of "8539.32.00 Mercury or sodium vapor lamps; metal halide lamps". See "Related Links" below for the US government's online list of Harmonized Tariffs.
