Metal Halide

Metal halide lamps are similar to mercury vapor models except for the addition of metal

halides of sodium iodide and scandium iodide. Certain metal halide lamps feature other iodides to improve the efficiency and color balance of the lamp. Metal halide represents the most popular and widely used HID category.

Typical applications: General lighting such as commercial/industrial/outdoor flood lighting where good color

and high efficiency are desired.

Arc Tube

There is a series of HID lamps that has a protective glass shroud around the arc tube that acts as a barrier to block any particles from exiting the lamp’s outer bulb.

Since the arc tube of the HID lamp is a highly pressurized environment, it is mandatory that the fixture that houses the lamp have a protective lens. This lens will contain glass fragments or other hot particles should the arc tube experience a failure.

High Pressure Sodium/

Low Pressure Sodium (SOX)

This series of HID lamps incorporates solid sodium, mercury and xenon or a neon/argon gas mixture within the arc tube. This combination of metals and gasses produces an orange-white light in the high-pressure version and a yellow light in the low-pressure model. Both lamps boast a luminous efficiency that is much greater than its mercury vapor or metal halide counterparts.

Typical applications:

Street lighting, industrial hi-bay, parking lots, building flood lighting and general area lighting.

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.
