ANSI Codes

All HID lamps and ballasts are identified by an ANSI code. The purpose of these codes are to make sure that the lamp from one manufacturer is properly matched to any other manufacturers ballast, therefore resulting in safe operation, and produce the designed light output. Especially with the increasing complexities of metal halide product offerings, it is very important that the ballast and lamp ANSI codes are matched before use. The most recent changes to the ANSI lamp codes have added the E, S, and O letter designations. For example, a 400 watt probe start metal halide lamp will have an ANSI code of M59/E, M59/S, or M59/ O. This should be used only on a ballast with an ANSI code of M59.

E - Lamps must be used in enclosed luminaires which meet the requirements of UL1598.

S - Lamps are considered “suitable” for open luminaire operation, only if operated in the vertical ±15° position. Lamps do not meet ANSI criteria for containment and must be turned off at least once per week for a minimum of 15 minutes if operated continuously. In addition these lamps must be group relamped before reaching rated lamp life.

O - Lamps can be operated in open or enclosed luminaires within the manufacturer’s specified operating position limits. This type meets the ANSI criteria for containment rated operation. Special exclusionary sockets are available for these lamps to ensure that the wrong lamp type is not used.

Rated Life

The rated life of metal halide lamps is based on the point when 50% of the lamps have burned out, based on a burn cycle of 10 hours per start. Various operating conditions affect lamp life. One key factor is operating position. Lamps designated universal can be operated in any position. However, life expectancy and lumen output are sacrificed in certain positions. Published “rated life” for universal lamps is based

on operation in the vertical position. “Rated life” for universal lamps operated horizontally is 75% of the published rating. Shorter operating cycles also severely reduce life. At operating cycles shorter than 10 hours per start, life will shorten as follows:

5 hrs per start: Life is approx. 75% of rating

2.5 hrs per start: Life is approx. 55% of rating

Initial Lumen Listings

Rated initial lumens are based on measurements at 100 hours of use, and are based on specified burning position. The measures listed for universal position lamps are based on a vertical burning position; horizontal usage decreases the output by 25 to

30%. For specifics on any particular lamp, call Satco customer service (800-43-SATCO).

Safety Warnings

It is the responsibility of the purchaser to read all safety warnings on the lamp package before use. For more information, call Satco customer service (800-43-SATCO).

HID lamps

Steps to choosing the correct Metal Halide lamp.

1)Determine the correct wattage.

2)Determine the base.

3)Choose the shape. ED and BT style lamps are generally interchangeable

4)Determine the correct size, some wattages come in multiple sizes. For example, 400w lamps are standard ED37, but are also commonly available in an ED28 compact envelope.

5)Determine burning position, BU, BD, Vertical, Horizontal, or Universal.

6)Determine Pulse Start, or Probe Start. Pulse Start is standard on lower wattage lamps, (39 through 150 watts). Probe Start is standard on higher wattage lamps, (175 through 1500 watts), however Pulse Start technology is being used more and more on the higher wattages.

7)Determine whether the project is calling for the newer Ceramic Arc tube lamps. These lamps offer higher color rendering, and Lumen Output than the more traditional Quartz Arc tube lamps.

8)Determine whether fixture requires an Open Rated (Protected) lamp, or an Enclose Rated lamp.

9)All Metal Halide lamps and ballasts are identified with an ANSI code. It is best to make sure that the ANSI code matches between the ballast and lamp.

HID Lamps specifications

Satco Products is a leader in the lighting industry, renowned for its wide array of high-quality HID (High-Intensity Discharge) lamps. These lamps provide efficient and powerful lighting solutions, ideal for diverse applications ranging from industrial and commercial spaces to outdoor lighting.

One of the primary features of Satco HID lamps is their impressive lumen output. These lamps can produce a significant amount of light while using less energy compared to traditional incandescent or fluorescent bulbs. This makes HID lamps a cost-effective solution for facilities requiring bright illumination.

Satco utilizes several advanced technologies in their HID lamps, including Metal Halide, High-Pressure Sodium, and Mercury Vapor. Metal Halide lamps are particularly favored for their excellent color rendering capabilities, making them suitable for areas where color distinction is crucial, such as retail environments and sports facilities. High-Pressure Sodium lamps are recognized for their efficiency and longevity, as they emit a warm golden light and are often used in street lighting, parking lots, and warehouses. Mercury Vapor lamps, while less common today, are valued for their reliability and are still used in some industrial applications.

The characteristics of Satco HID lamps further enhance their appeal. With a variety of wattages and sizes available, these lamps provide flexibility for numerous lighting designs and requirements. Their long lifespan, which can range from 12,000 to 20,000 hours, reduces maintenance costs and frequency of replacement.

Another notable aspect is the quick start and warm-up time of Satco HID lamps, particularly Metal Halide. This feature is essential in environments where immediate illumination is necessary, such as in stadiums or emergency response areas.

Furthermore, Satco is committed to sustainability, emphasizing energy efficiency in their products. Many of their HID lamps are designed to comply with environmental standards, contributing to reduced carbon footprints for businesses utilizing them.

In summary, Satco Products offers a comprehensive range of HID lamps characterized by their high lumen output, advanced technologies, and energy-efficient designs. Whether for commercial, industrial, or outdoor use, Satco's HID lamps provide versatile and effective lighting solutions that meet the demands of today's energy-conscious consumers.
