Factors to consider when buying the best HPS grow lights


The HPS grow light you plan to buy should be large enough to cover the plants. If your vegetation is growing in a 3×3 setup and the light only covers a 2×2 area, it is not worth it; otherwise, you will have to purchase two of these lights.

Also, make sure to buy the HPS grow lights depending on flowering coverage rather than the vegetable coverage.

Typically, this is a 4×4 vegetative cover that provides about 3.5×3.5 flower coverage, as the light requires to be brought down during the blooming phase and would therefore occupy a small area.

Power consumption

When buying the best HPS grow lights, you need to consider the power consumption. The more power the grow light uses, the higher the electricity bill.

The price of growing plants will increase if the HPS grow lights use a lot of energy. Always check the amount of power the light is drawing from the outlet before purchasing.


With the HPS grow lights you are dealing with, chemical fumes can be very toxic. You must ensure the device is safe for use and has every ratings and certification required by organizations like CE, FCC, etc.

Lighting details

You need to know the spectrum of which the HPS grow light operates and the PAR worth you get. The essential ideal applies to lighting where the brighter light is better.

Nevertheless, you may want a low bright light if you grow ornamentals or succulents and a highly bright light if you grow marijuana. Therefore, ensure you have the proper brightness.

Durability and design

The best HPS grow light is a good-looking and durable model which is well designed. Likewise, the design should not be too heavy or bulky.

These lights must be sturdy enough to withstand the occasional scratches or bumps in terms of durability. Waterproofing would be a huge benefit, but it’s rarely seen on these grow lights.

Cooling capacity

The best HPS grow light should have an efficient cooling mechanism. Since these lights are generally hot compared to fluorescent or LED lights, you need to pay attention to their cooling capacity!

Ensure the light has powerful fans, heating vents, and other comparable cooling features. Working temperatures must be kept low as possible.

Garden style

It’s crucial to consider the garden type to know which light is right for you. This could be an interior garden without natural light or a greenhouse. Since some plants are short-lived, especially in summer when they are sowed in a greenhouse, they don’t need much light.

Due to the growth system, some HPS grow lights have improved nutrition, climate, humidity, and temperature due to the growth system. All of this allows the average producer to achieve high yields. Besides, some lights require CO2, oxygen, and additional cooling.


Unfortunately, lights go out and need to be replaced from time to time. That’s why you don’t want to be caught unaware if a bulb explodes in the center of growing.

Just because you’re on a tight budget, it doesn’t mean you have to go for the low-quality and cheapest models on the market. Luckily, many good brands offer quality lights at affordable prices.


HPS grow lights prefer yellow and red-hued light that mimic autumn or fall light. In this spectrum, light stimulates the reproductive process of plants, like bud growth.

But plants require more red and yellow hues. Also, plants need light during the blue spectrum and with the HPS grow light with an extended spectrum will give the best outcome.

Some people choose the blue spectrum light through the plant’s growth phase. A yellow or orange HPS shade is recommended during flowering. When selecting a light, remember that buds and flowers work best with highly photonic infrared light or infrared radiation.


It is part of the HPS grow lights, beneficial in both large and small grow rooms. Typically, different ballasts include digital, electronic, and magnetic.

The digital ballast has become the common model that adjusts the voltage of the solid fluorescent light to manage overheating. It has the latest microprocessor technology to monitor and stabilize the voltage received by the light.

Additionally, this ballast gives the growers additional flexibility to manipulate and regulate the voltage received from the lighting system.

With the digital ballasts, you will control and regulate the lights’ voltage between 400 and 1000 watts. Likewise, this feature permits you to manage the heat of the lighting system to a safe level. However, the efficiency of the ballasts must exactly match the electrical requirements of the light it regulates.

Digital ballasts might be a significant investment, but they effectively develop long-term. The design allows for up to four lights at a given voltage.

Reflective style

The reflector improves the focal point of the HPS grow light and saves the bulb’s life. Typically, there are two reflectors types: air-cooled and open style.

The air-cooled reflector contains openings on both sides that direct air into the reflector. Captures hot air and keeps it away from vegetation.

The concave reflector is planned so that the plants receive a lot of air. It contains an exciting feature that permits you to regulate the light near the plant. This method is perfect for indoor plants.


This factor is also very significant when buying the best HPS grow light. Although all HPS lights have metal material, you should choose a high-quality, durable metal lamp that can withstand excessive heat also normal wear and tear.

But if the metal is very thin or brittle, the light will break quickly, or worse, dangerous. German hammered aluminum is the most durable fabric for HPS grow lights.
