What Does High Pressure Sodium (HPS) Mean?

A high pressure sodium (HPS) light is a type of grow light that is commonly used for indoor gardening. This particular light stimulates plant growth by diffusing the portion of the electromagnetic spectrum that is ideal for the whole process of photosynthesis. High pressure sodium lights are also used to prevent the plants from growing overly spindly and long. It mimics general outdoor conditions, especially as far as color and temperature is concerned.

HPS bulbs, along with other types of grow lights such as metal halide (MH) and mercury vapor (MV) are known as high intensity discharge (HID) lights.

Benefits of Using HPS Grow Lights

Why should you use an HPS grow light as opposed to all the other types of grow lights on the market? There are a number of benefits to these lights that make them the best choice:

Mimic Natural Light

Plants thrive when they have the wavelengths and strength closest to their natural amount. HPS grow lights are the best at doing just that, and their light contains a spectrum almost identical to the sun. Combined with the strength of a given ballast, a plant will receive optimal amounts of light to grow- sometimes better than it would in nature.

Powerful and Effective

One of the biggest benefits of HPS grow lights is their high potential for light output. A 1000W HPS bulb, for example, gives off 130,000 lumens of light at 1150 PPFD, compared to other forms of lighting that offer far less lumen output. That means you can grow a wider variety of plants than you would with other grow lights.


For starters, HPS bulbs are as affordable as grow lights come, and you’re not sacrificing any quality for the price! Plus, if one part of your HPS light system fails, it’s easy and cost-efficient to replace as opposed to having to buy a whole new system.


Most HPS lights have dimmable ballasts. This makes it easy to control the intensity of light your plants are getting to ensure optimal intensity.


There are a lot of different types of reflectors to give you the light that your plant and spatial needs. No matter if you need tons of light for lots of plants or a little bit for a few, there's an HPS grow light to suit any indoor garden and gardener.
