Colors are created by using different arc tube designs and changing the mixture of chemicals within the tube.

HID Basics

HOW IT WORKS

The operational concept behind HID lamps is very similar to that of fluorescent lamps. Electrodes are positioned at either end of a tube, whose chamber is filled with gas and metals such as mercury. An electrical charge passes from one electrode to the other. In fluorescent lamps, this charge creates ultraviolet (UV) light, which converts to visible light once it passes through the phosphors on the tube’s interior.

In an HID lamp, the electrical arc, gasses and metals are contained in what is known as the arc tube. The arc tube is made from either quartz (used in mercury vapor and metal halide lamps) or transparent ceramic (used in high-pressure sodium lamps because of their high temperature). All arc tubes are housed within a larger outer glass envelope.

Unlike fluorescent lamps, the arc tube of HID lamps is filled with gas at a very high rate of pressure (up to 50 psi). This allows the electrical arc created by the electrodes to operate in the visible part of the spectrum, producing usable light without the addition of phosphors.

Like fluorescents, HID lamps require a ballast to control the electrical current in the arc tube. Certain HID lamps also require an ignitor, which produces a high voltage to pulse the arc tube, allowing the arc to strike.

The biggest difference in HID lamps is the fact that they need a start-up time to reach their full brightness. This usually takes five to 10 minutes, during which time the lamp will flicker until the metal inside fully vaporizes and the lamp reaches is full operating temperature.

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.
