High-Pressure Sodium Grow Lights

High-pressure sodium (HPS) lamps are best used when color rendering is not of great importance.

High-pressure sodium (HPS) lamps are best used when color rendering is not of great importance. They are a good alternative to metal halide lamps but have a lower color-rendering index (CRI) rating. HPS comprises a compact grow light system with high lumens, and is an often recommended as a
high-intensity discharge (HID) option.

The color temperature you need depends mainly on the type of crops you're growing. For most plants,
however, high-CRI and low-CRI systems make no observable difference. On a scale of 1-100, 100
represents artificial light that is identical qualitatively to natural sunlight.

HPS systems can produce a high-powered beam, but the light must be managed efficiently. Many HID
lights take several minutes to warm up and in the process waste power, which can be expensive as well as dangerous. Some HPS lights have occupancy sensors that dim the output automatically when unattended, reducing the output to a fraction of their capacity.

Hydrofarm makes one of the most widely used HPS systems on the market. These HPS lamps are quieter than most compact systems and have good ventilation to keep them cool. Their rugged steel design ensures durability. The well-built transformer mounting and housing unit are designed to withstand plenty of bumps.
