High Pressure Sodium Lights - Features and Applications

High pressure sodium lights are a type of lighting called High Intensity Discharge or in short term know as HID. Among other types of high intensity discharge lighting also includes metal halide, mercury vapor and low pressure sodium.

One of the good things about high pressure sodium lights is that they generally have a greater light output, although they require special ballasts and fixtures for each specific lamp. One of the characteristics of these high pressure sodium lamps is the bulb produce golden white light or sometimes people say yellowish. Due to their energy efficiency, their maximum use is seen in industrial,  security lights, roadway lighting others are used to light the sides of landmarks and buildings.

Other than industrial usage, many indoor growers and hydroponics enthusiasts use high pressure sodium grow lights because they are high in reds and yellows on the light spectrum. Before that, hydroponics is one of method of gardening without utilizing soil. In this technique, food and water are supplied directly to the roots of the plant. Therefore, the root system does not need to develop in search for food and water. Thus, the energy that normally used to search for food is use by the plant for faster upward growth together with better rate of fruit production.

Since no soils are needed, hydroponics enables you to grow beautiful flowers and vegetables virtually anywhere even indoors with proper lighting conditions which made available by high pressure sodium lights. In an indoor hydroponics system or indoor planting, plants receive sunlight through imitation means such as high pressure sodium lights.

The major advantage of high pressure sodium light is its high efficacy in lumens per watt along with long lamp life. As compared to the usage of mercury vapor and incandescent, they reduce electricity costs to great extend.

Following are some examples of high pressure sodium lights systems and accessories available in the market and even you can get them by purchase from the internet.

400 Watt Electronic Ballast Hydroponic Grow Light Lamp

This 400W hydroponics lighting system represents the best value grow light. Its advanced electronic ballast supports both High Pressure Sodium (HPS) and Metal Halide (MH) bulbs, giving the grower the flexibility to choose the best selection simply by changing the bulb, instead of having to own two separate light systems.MH is used for accelerated vegetative growth, then switch to HPS to encourage flowering, fruiting and budding.

Hydrofarm Sunburst System 400W High Pressure Sodium (HPS)

UL Listed features self-contained ballast and a smaller diffused specular aluminum reflector for optimal intensity and the option to air cool. High Pressure Sodium (HPS) Lamps have initial lumens between 120,000-140,000 lumens and deteriorate slower than metal hallide lamps. They are dominant in the red-yellow spectrum and possess minimal amounts of the blue-green spectrum.
