HPIDD100-240-C Dimensions

With the removal of the ignitor and capacitor from the lighting circuit, electrically the HPIDD100-240-C can be used to replaced traditional wire wound chokes; such as the NAHJ 100.941

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.

Harvard Technology was a UK-based company specializing in smart lighting solutions, including LED drivers, light engines, and wireless control systems like the LeafNut and EyeNut systems. The company’s original business faced administration, but its assets were acquired and its products, particularly LED drivers and sources, are now sold under the new entity, Harvard Power Systems, which is part of the Gallant Lighting Group. The original company was known for pioneering early wireless smart lighting technology for both indoor and outdoor applications.
