Sun System HPS 150W is a great choice for small indoor farms. It has quite a low output wattage - 150W; however, with the highly reflective aluminum insert, the light produces a huge amount of lumen, which is a measurement of the light intensity on the surface. Moreover, Sun System HPS 150W produces a natural spectrum. So, the light meets the need of almost any plant.

Sun System HPS 150W is very easy to set up and use with replaceable parts. So the lifespan of the product may be really long. However, since this is a small light setup, it is only suitable for a small garden crop - about 3 x 3 ft.

Best For Beginners: iPower GLSETX400DHMWING 400 W

iPower 400W has medium and stable power output, 400W. This ensures flicker-free light. You can adjust the intensity of light - there are 3 dimmable options: 50%/75%/100%.

Like two lights above, iPower 400W produces a natural spectrum with a high PAR, ideal for all types of plants in all stages of growth. The bulb is replaceable, you can replace it with HPS & MH bulbs.

iPower 400W comes with a 19-inch Wing Reflector, which can cover an area of 4 x 4 ft. Wing reflector is the cheapest type of reflector but has the highest reflective effect - up to 95%. However, the wing reflector generates a lot of heat. You don't want to use this lamp in an enclosed area without ventilation.

Best For Seasoned Gardeners: iPower 600 Watt HPS MH Grow Light

Basically, iPower 600W is a higher-power version of iPower 400W. Everything is pretty much the same, except this light has higher output wattage - 600W and a 6-inch Air Cooled Hood Reflector. iPower 600W can cover up to 5 x 5 ft.

The air-cooled reflector is the most effective type of reflector. It is ideal for grow tents; moreover, it does not generate too much heat that can damage the plant. Although it is not overly hot, you’ll don’t want to place iPower 600 in an enclosed area without ventilation, which may reduce the product’s life.

How To Choose The Best HPS Grow Lights?

Although LED or COB grow lights are getting more and more popular these days, HPS grow lights with old-fashioned technology remain their place in the market. HPS or High-Pressure Sodium lights are favorable thanks to their natural spectrum, which is like the sunlight. This type of light is perfect for the plant to thrive. HPS lights also have a price to start with; they produce a massive amount of light as well. However, HPS lights also have some disadvantages. They produce a lot of heat, consume a log of electricity, and are not so durable. So, it depends on your preference to choose the type of grow light.

When choosing an HPS grow light, you’ll need to pay attention to some specs.

• The output wattage: The more the output wattage is, the more bright the light is. A small HPS light has the output wattage of 150W, medium ones have about 400W or 600W.

• Type of reflector: There are three types of reflectors - Air Cool Hood, Cooled Tube, and Wing Reflector. The air-cooled reflector is the most effective type of reflector but more expensive. The cooled tube reflector can fit in a small place and dissipates heat effectively but does not reflect very much. The wing reflector has an impressive reflecting effect, can cover a large surface area, and is affordable but can get very hot. It depends on your preference to choose the right type for your system.

• Coverage: You’ll want a grow light that can cover nicely your indoor garden. A small HPS grow light can cover 3 x 3 ft surface; some bigger HPS grow light can cover 4 x 4 ft or 5 x 5 ft surface.

• Dimmable options & Safety features: Dimmable option is a good feature to adjust the intensity of the light to feet your plant’s need. Safety features include Overheating Protection; End-of-Bulb-Life Protection; Short Circuit Protection; Ignition Failure Protection.
