High Pressure Sodium Lamps

HPS (High Pressure Sodium) lamps are a type of high-intensity discharge lamp known for their energy efficiency and high light output, producing a distinctive yellow-orange glow.

They are commonly used for outdoor area lighting like streetlights and for commercial growing, especially during the flowering and fruiting stages of plant growth, due to their intense, deep-penetrating light spectrum. Key features include a long lifespan, a ballast to regulate current, and a warm-up period to reach full brightness.

How they work

An electric current is passed between two electrodes at the ends of a ceramic arc tube.

The arc tube contains a mixture of mercury, metal salts, and sodium.

Xenon gas is used as a starter gas to help strike the arc.

As the arc is struck, the xenon and mercury are ionized and the arc tube heats up.

As the temperature and pressure increase, the sodium vaporizes and the characteristic yellow-orange light of the HPS lamp is produced.

The outer glass envelope insulates the arc tube and contains a vacuum or inert gas to help manage heat.

Metal halide Lamps

Metal halide (MH) lamps are high-intensity discharge (HID) lights that produce bright, white light by passing an electric arc through a gas mixture of vaporized mercury and metal halides.

They are known for high luminous efficacy, long lifespan (compared to older technologies), and excellent colour rendering, making them suitable for large indoor and outdoor areas like sports arenas, warehouses, and streets. However, they require a ballast to operate and have a warm-up period to reach full brightness.

How they work

An electric arc is struck between two electrodes inside a quartz or ceramic arc tube.

The arc vaporizes mercury and other metal halides (compounds of metal and halogens like bromine or iodine).

The mixture of vaporized gas and metal halides creates a high-intensity, full-spectrum light when energized.

Wire wound ballasts, commonly known as magnetic or electromagnetic ballasts, are traditional, durable components used to regulate the current flowing through fluorescent and High-Intensity Discharge (HID) lamps. They consist of copper wire wound around an iron core (a “choke”), which acts as an inductor to limit current, prevent lamp burnout, and provide the initial high voltage needed to strike an arc in the lamp.

Key Aspects of Wire Wound Ballasts:

Functionality: They provide an initial voltage boost to ignite the lamp and subsequently limit the current to a safe, stable level to prevent the lamp from drawing too much power.

Design & Construction: These are robust, heavy, and simple components, often containing copper coils and iron sheets. They are sometimes referred to as “chokes”.

Performance Characteristics:

Flicker & Noise: They operate at low frequencies (50/60Hz), which can cause noticeable humming, buzzing, or flickering.

Energy Efficiency: They are less efficient than electronic ballasts, often consuming about 30% of the rated lamp power as heat.

Lifespan & Reliability: Known for being rugged and durable, they are often used in industrial settings.

Applications: Primarily used for older fluorescent tube lights and HID lamps (metal halide, high-pressure sodium).

Vs. Electronic Ballasts: While electronic ballasts are more efficient, quieter, and flicker-free, wire wound ballasts are often considered more robust.

Maintenance: They can fail over time, often indicated by buzzing, flickering, or a burning smell. They may require a starter to initiate the arc.

Legacy Technology: Magnetic ballasts are increasingly being replaced by electronic ones, but remain in use where they were originally installed.
