Sodium vapor lamps are gas-discharge lamps that use sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Two varieties of such lamps exist: low-pressure and high-pressure. The high-pressure types of fluorescent growing lamps emit high levels of light with a color temperature of approximately 3000K.

HPS lamps have many benefits over other types of grow lamps because they produce a large amount of usable light while maximizing lumens per watt. In other words, HPS bulbs will consume less electricity than other forms of lighting while producing the same level of usable lighting for your plants.

Another benefit to HPS lights is the lifespan of about 24,000 hours and is fairly cheap to replace compared to the metal halide bulbs. When using HPS lights consumers do not run the risk of coming into contact with mercury, infrared, or UV lights that can cause harm to animals and people.

HPS bulbs are an excellent choice for most indoor grow operations because they simulate the natural light spectrum, which generally leads to higher quality and higher yield of plants. Also, since the light spectrum is similar to natural sunlight, the plants will remain healthy and develop a good structure with good roots and strong stems.

This article will discuss the pros and cons of the best HPS bulbs available in the market for your convenience.
