Gardening is a beautiful thing. It is a noble thing to do. However, gardening comes with responsibilities. We all want to create the best possible conditions for our plants to grow. How to define it? Well, we want them to be happy. That is because for us gardening is not something ordinary, boring.. it is not a job. It is a pleasure.

As a gardener, l always want to ensure that my plants have the best possible equipment to help them develop. Because of that, l pay attention to every single detail.

Therefore I have created a list of HPS grow lights that l have found the most satisfying and worth reviewing.

HPS grow lights (High-pressure sodium lights) emit light in the red/yellow perceptible light. It can emit fragments of other visible lights as well.

These lights serve as a kind of help to daylight in greenhouse lighting. Of course, it can be used as the only source of light for grow/indoor chamber.

Nowadays, even football stadiums use the HPS grow lights to foster grass growth.

MIXJOY 1000 Watt

Another HPS grow light kit. MIXJOY has various products to offer. If you prefer LED grow lights they have it, as well.

Anyway, l did my research and saw that they were not so popular among gardeners and farmers around the world.

That was surprising for me because they have a wide range of available products on Amazon. Honestly, l think it is the question of time when they will become globally well-known.

When it comes to MIXJOY 1000 Watt Double Ended Grow Light System kit one can see that it is a high-cost product. Moreover, I think that there are more cost-effective solutions in the market.


  • Brand: MIXJOY
  • Max Wattage: 1000W
  • Material and shade material: Aluminum
  • Light source type: HPS

What plants is it good for

A huge output of PAR light (2,050 μmol/s) fosters photosynthesis. Moreover, because the bulb emits a lot of UV and IR light, it increases the essential oils of the plants and potency.

The great number of emitted lumens will surely help you if you have a huge garden.

Key features

Like with other kits, this HPS grow light kit comes with all components you need: digital dimmable ballast, aluminium reflector, double-ended HPS 1000W bulb, power cord and 8ft rope.

I do not think that you will have any serious issues with a setup. The assembly of this product is generally easy.

The digital dimmable ballast is specially designed and developed for double-ended grow lights. It is adjustable for various outputs (600/750/1000/1150W). It runs on a 120-240V power supply. 240V adapter is included.

VIVOSUN Hydroponic 4-Pack

And the last product that we will show you today is again, VIVOSUN’s. We all know that bulbs should be changed at least once a year.

That is because we want to keep the performance of our grow light kit on the highest possible level. Therefore, VIVOSUN saw the opportunity and made a pack of four HPS grow light bulbs.

Because the bulbs should be changed regularly, and because they can unexpectedly break at some point, it is always good to have some put aside.

Therefore, I think that this is a good investment for people who need to have continuous grow light for their plants, flowers, fruit or vegetables.


  • Brand: VIVOSUN
  • Wattage: 1000W
  • Special features: Enhanced orange and red spectrums

What plants is it good for

A red and orange spectrum lights are one of the most energy-efficient “springs“ of indoor lighting. It can extend the growing season, as well.

Generally, it is used through the vegetative, fruiting and flowering periods. The yellow spectral output, for example, makes them ideal for flowering.

Key features

Generally, l think that VIVOSUN HPS bulbs have better efficiency than ordinary bulbs. Their efficiency is great, therefore they have a strong penetrating force.

However, although these bulbs are very good they are a consumable product. Regardless of the light bulb type (HPS, LED, fluorescent, incandescent, MH), the lumen will decrease in time.

Of course, as all serious lights do, this one emits red and orange spectrum lights, as well. These bulbs can emit around 140,000 lumens with appropriate ballasts. 

The manufacturer advises, and honestly, l agree that the bulbs should be changed after 12 months of continuous use. It is because of the decreased performance rate and safety of your plants.

In order to light up this bulb, your ballast needs to reach the standard. The standard is: output frequency- 100K, and the trigger voltage of your ballast must be at least 7000V. These grow lights high pressure sodium are compatible with magnetic and electronic ballasts.

Of course, because VIVOSUN is manufacturing ballasts as well, they offer their dimmable, electronic ballast to pair with these HPS bulbs.

However, you can choose whatever ballast you want, as long it has the same watts as the bulb when igniting. Moreover, the addition is to be able to adjust the lumen of the bulbs.

You should always be careful when igniting the bulbs. Always give them a few minutes to cool down if they are hot.

What we like
  • Optimized orange and red spectrum
  • High PAR (Photosynthetic Active Radiation)
  • Reliable
What we don’t like
  • Cannot lighten up if the ballast cannot reach the standard

Things to Consider When Buying HPS Grow Lights

1. Wattage

I believe that, for serious indoor gardening, anything below 400 watts is pretty inefficient. I have mentioned that with the 600 watt HPS grow light you get the most proportion of light per watt of electricity.

However, it depends on the size of your garden, as well. For example, 600w grow light covers 16 square feet.

Moreover, many would agree that it is better to cover your grow space with more 600w grow lights than with less 1000w.

Anyway, it is up to you to make that choice.


Most kits include these two types of light bulbs- HPS and MH (metal halide in case you have never heard of it).

I would recommend you to use both because the plants would need both. How? Well, HPS bulbs give you a lot of orange and red light, and it is great for the flowering stage.

However, for plant growth, you need cooler light (light with a lot of blue color in it). Therefore, that is why you need MH bulbs. Of course, you will not need HPS bulbs if you are growing plants that do not flower.

To conclude, vegging stage demands for the MHs, the flowering demands HPS’.

3. Double-ended and single-ended type of bulbs

This is another thing you should know before buying a bulb or kit in general. Firstly, let me pinpoint that for beginners I strongly recommend buying a kit.

It includes everything you need and you will understand how for example 600w HPS grow lights function.

Generally, the main difference between double-ended and single-ended bulbs is that double-ended last more.

Moreover, they give you a stronger output. However, at the same time double-ended are more expensive and they generate more heat.

Therefore, if you are a starter, go with the single-ended. Later, you can make a choice based on your own experience and not only on the recommendation.

Frequently Asked Questions

How far should a 1000 watt HPS light be from plants?

Of course, the distance between the bulb and the plant varies. Everything depends on the HPS wattage. You should always know that too much light is as bad as little light.

Therefore, be very careful when adjusting the distance. The 1000 wat HPS light is the hottest and the strongest. They should be placed around 5 feet (152.4 centimeters) above the plant.

Why is HPS better than led?

I am in love with the results of HPS bulbs. The best HPS grow lights have a balance between intensity and light penetration, 600-watt HPS grow lights, for example, are much more cost-effective than LED, and finally HPS is more consistent.

Is HPS best for flowering?

HPS fosters maximum flowering because, due to the red and orange output, it looks like the natural sunlight. Moreover, HPS grow lights provide more than enough lumens. Therefore the results are better and yes l can confirm this. 


There are a lot of factors that can influence your decision. You choose the best HPS grow light according to the size of your garden and your own needs.

Like l mentioned, I advise you to start with an HPS grow light kit. Therefore, due to the efficiency, l would recommend VIVOSUN Hydroponic 600 Watt HPS. I hope that these reviews will help you to make the best conditions for your plants.
