Choosing Between LED and HPS Grow Lights

Before selecting which Luxx or Gavita grow light is best for your cultivation, it’s important to first decide if you’re going to go with LED vs HPS.   There have been many articles written about the differences between LED and HPS, but for the purposes of this comparison we’ll break it down for you quickly:

  • LED grow lights are the only lighting option effective for grow racks
  • LED grow lights are more efficient and will deliver a higher ROI
  • LED grow lights come with better grow light controls
  • HPS grow lights are much cheaper upfront, but more expensive to run
  • Both LED and HPS grow lights will grow high-quality product

When comparing the Luxx and Gavita product-line, you must first determine whether you’ll be growing indoors or in a greenhouse. If you’re growing indoors, there’s great benefit to stacking your lights on vertical racks to double your plant yields. If you do decide to grow vertically, you’ll want to use either the Luxx 645 or Gavita 1700e.   If you’re growing in a high-bay or greenhouse application, we strongly recommend that you do your research on the benefits and disadvantages of LED vs. HPS grow lights to determine if the Luxx Lighting 1000W DE and Gavita Pro 1000W DE will suit your needs.   If you have additional questions on the best LED vs. HPS grow lights for you, our advisors are happy to point you in the right direction when you book a consultation.

#2  Grow Light Output

Grow light output is much like comparing horsepower for your car. You may not use it at max capacity all of the time, but you always want more.

led grow light output

Comparing light output for the Luxx 645 LED Pro vs. Gavita 1700e LED is a lot like comparing a Ford Mustang and Dodge Challenger. They both go fast, and you don’t buy either one for the negligible boost in HP.   The Luxx 645 LED comes in at a strong 1727 umol/s, with Gavita slightly winning at 1745 umol/s. Since cannabis photosynthetic photon flux density (PPFD) requirements hover around 700 to 800 μmol m-2 s-1, we’ll call this light output comparison a wash because both LED lights are capable of meeting robust flowering goals.   But don’t take our word for it. Below we’ll dive into the details of PPFD for powerful Luxx and Gavita fixtures.

#3  Coverage, Uniformity & PPFD

When looking at the light coverage for the Luxx 645 LED Pro and Gavita LED, it is important to keep in mind that cannabis needs vary between 150 and 800 PPFD depending on the stage of the growth cycle.   Both Luxx LEDs and Gavita LEDs are capable of full-cycle plant development, so you can run a crop from propagation through flower in the same grow rack.   Still, it’s important to consider the hang height of your light fixture in your racks, as well as the width of your grow trays. In a grow tent, this hang height is less important due to the enclosed reflective space. But in plant racks, a high hang height may mean that you’re losing light in your aisles.

#4  Luxx vs. Gavita LED Light Spectrum

If light output is like your cars horsepower, then light spectrum would be the handling. Choosing the appropriate light spectrum, or using a grow light controller to adjust your light’s channels  will determine how your plant will grow.   Both Luxx 645 Pro LED and Gavita 1700e are extremely similar in the light quality they produce. The Luxx uses a 3900 Kelvin light spectrum, while the Gavita 1700e uses a 3000 Kelvin spectrum with additional 660 nanometer (nm) Osram red diodes to balance the spectrum for full-cycle production.   You’re not going to find much difference in terms of spectral performance from these fixtures, again making both good options for cultivation at any growth stage.

#5  Cooling

Both the Gavita 1700e and Luxx 645 LED are passively cooled, meaning that there are no fans to collect dust and debris.   Although there may not be a sticking point between these two LED grow lights in this lineup, you may want to consider the risks of actively cooled fixtures if you’re to compare Gavita vs. Luxx against other LED grow light brands.   With so many similarities between Luxx and Gavita, you now can see how it really comes down to brand and price.

#6  Pricing

Like most things in life, it has all come down to the price you pay. Again, both fixtures are similarly priced, with some large fluctuations on reported MSRP online for Gavita, with some distributors reporting as high as $1,499 per fixture.   The fixture quality and performance is similar between the Luxx 645 LED Pro and the Gavita 1700e LED, so depending on your scale of facility you will want to choose carefully.   Both LED grow lights command great brand recognition in the market, and oftentimes with grow lights it’s the brand you’re paying for.


MSRP *(estimated) $1,099 $1,099 to $1,499
MSRP/Watt *(estimated) $1.70 (estimated using $1,099/fixture) $2.09 (estimated using $1,299/fixture)
MSRP/PPF *(estimated) $0.64 $0.74

Great Light! Great Customer Service! What more can we ask for!  

Anonymous | Gavita 1700e LED Review

I went with the 1700e. No qualms whatsoever. The price of the 1700e is still a little high, but I’m happy with the performance.


The Luxx 645 Pro LED and Gavita 1700e LED are both well-designed, high performing grow lights for full-cycle development.   All other things equal, such as 5-year warranties and useful rated lifetimes, choosing between the two is really like choosing which look and feel you prefer the most.   For hobbyists and small cultivators, the MSRP for the Gavita may cost you more depending on the deals you’re able to find. Competitive commercial pricing is offered for the Luxx 645 Pro LED, making it a great value for commercial cultivators interested in performance over all else.   To get competitive commercial pricing on grow lights and for a complimentary consultation and lighting report, contact an advisor today to get started.
