HPS vs. LED Grow Lights — Which is Better for Growing Medical Plants?

Pick UPS or LED for indoor plants

For growers, plant grow light is already essential tools. There are additionally lots of kinds of expand lights on the marketplace to pick from. From the difference of light grains, they are mainly divided into HPS and also LED

There have been a lot of misconceptions over the years regarding which option is the superior selection. What’s the distinction in between LED and also HPS? What type of light should I pick for my plants? This is one of the most usual plant growers concerns.

If you’re wondering which choice is right for you, keep reading. You will get the solution.


A light-emitting diode is a semiconductor light that emits light when current circulations with it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.
The shade of the light is established by the power needed for electrons to cross the band gap of the semiconductor. White light is obtained by using numerous semiconductors or a layer of light-emitting phosphor on the semiconductor gadget.


HPS represents High Pressure Sodium. HPS lights give a full spectrum of light yet have an emphasis on the red end of this range. They can be made use of for the whole life process of a cannabis plant.
HPS lamps have actually been widely utilized in industrial illumination, especially in huge manufacturing centers, and also are frequently used as plant grow lights.

5 Advantages of LEDs

Efficiency— LED diodes are extremely electrically effective and also give off more lumens per watt than incandescent light bulbs. The effectiveness of LED lights fixtures is not impacted by shape and size, unlike fluorescent light bulbs or tubes.

Dimming— LEDs can very easily be dimmed either by pulse-width inflection or decreasing the ahead current.

Cooling— The majority of LED lights have heatsinks and little built-in followers to help disperse heat up as well as far from the light, which lets them run cooler.

Life time— LEDs can have a relatively lengthy useful life. One report quotes 35,000 to 50,000 hrs of beneficial life. Fluorescent tubes typically are rated at concerning 10,000 to 25,000 hrs and incandescent light bulbs at 1,000 to 2,000 hours.

Spectrum— It is recognized that the shade spectrum of light influences exactly how plants expand. Each LED diode can be set up to emit light of a really particular color spectrum picked by the customer.

Disadvantages of HPS

The primary trouble is usually the warmth created by both the ballast as well as the light. With temperatures exceeding 400 ° C, this system does not use power really efficiently. The infiltration of these lights also lessens extremely swiftly and can come by virtually 90% at range of just one meter.

HPS lights make use of a ballast, and also few to none are FCC compliant or UL noted. Their ballasts are seldom examined and also removed for security. HPS is a larger potential fire risk since they obtain hotter as well as produce even more concentrated warm.

It may take 5 to 10 minutes after the HPS begins to reach full light output. They also call for at the very least a one minute cool-down to re-strike.

When you read below, I assume you already have the solution. LED lights can offer long-term cost savings and also power effectiveness, as well as do not call for additional devices. Although the ahead of time expense of LED lights is usually greater than that of HPS lights. With long-term savings, investing in high-quality LED illumination systems is the only means to go. Whether you require LED lights for massive expand or little procedures, we have something to fit your requirements!
