The LED grow light industry has gotten to a point where it can finally deliver the same quality to the small scale grower as it can to large commercial operations. Most importantly, it can do so without breaking the bank.

As many will recall, it wasn't all that long ago that small to medium to sized growers were priced out of quality LED lighting options. Unless you had bottomless pockets, you couldn't afford to shop for LED grow fixtures.

It's not the case today, with a recent series of high powered LED lighting options targeting the small-time operation. Today, LED grow lights are well worth the investment.

These fixtures have come down in price, but crucially still deliver the high-quality performance expected from commercial installs. These options are an affordable and approachable fixture for even the home grower.

FULL SPECTRUM LED GROW LIGHT provides plants in all stages from veg to flower with everything they need in the natural sunlight. 

Here we will compare two notable options on the market today:

  • Growers Choice ROI E-680
  • Fluence SPYDRx PLUS

For the home hobbyist or small scale craft cultivator, there are a few notable LED grow options now. Of particular note is the Growers Choice ROI E-680 fixture. It's a unique collaboration between two industry leaders (TSL Horti Tech and Grower's Choice), and one which dominates its competition.

Without getting ahead of ourselves, the ROI E-680 fixture is the best in the market today, in nearly every category worth comparing. It clearly meets or beats conventional lighting when it comes to performance, and as we'll see, the ROI E680 beats the LED options as well. 

In our experience, the price point, output, efficiency, and features of the Growers Choice fixture make it a clear choice for any operation.

 

By far the most powerful LED in its class with a standard PPF of 1850 umol/m2/s and a “BOOST” mode that raises the output to 2050 umol/m2/s, for professional cultivators who demand ultimate light output.


The ROI-E720 was engineered with greater dimensions to provide more versatility and better canopy coverage, especially to the outer edges of 4’x4’ cultivation areas.


The ROI-E720 is IP65 water-resistant rated, UL8800 certified, and Horti DLC certified for energy efficiency rebate eligibility. With unbeatable safety, reliability, savings and performance, the ROI-E720 is unquestionably the right choice for cultivators who demand only the best.

The SPYDR 2i 40" provides excellent coverage over a 4' x 3.5' canopy. Perfect for smaller areas or to fill in rows where another full-sized (47") 2i would more be than what's needed (e.g. using two 2x 40" fixtures plus one 47" fixture to cover a perfect 11' long row).

All SPYDR models are dimmable with our light intensity Dimmer for precise control over PPFD and offer flexibility to instantly accommodate a new crop with varying light requirements.

The SPYDR 2i is a high-performance top-lighting solution for commercial horticulture cultivation. Designed for growers to push the envelope with high-PPFD cultivation practices. Not intended for grows without CO2 supplementation.

PhysioSpec Indoor is a full-cycle spectrum optimized for rapid growth and complete plant development. Tailored for growing plants from initiation to senescence (germination, clones/cuttings, mothers, vegetative and flowering applications) in indoor environments.  With a CRI rating of 85, PhysioSpec Indoor offers a beautiful work and research environment with vivid colors and greater contrast to study the health of your crop.

Space Considerations

All two LED grow lights on this list are passively cooled LED light bars. This means, based on the fixture design of long bars attached to an open metal frame, the heat considerations are minimal. They have no reflectors and have a significantly lower profile than traditional lighting options.

Additionally, this means no monstrous HVAC and cooling systems to keep the environment stable and safe — instant space savings on this point.

The ROI E-680 fixture requires at most 12" between the canopy and the fixture. Some growers report as little as 6", however, that may depend on perfecting all other environmental conditions.  The SPYDRx PLUS seems comparable, with similar height suggestions to the ROI E-680.

During flower, set at a lower intensity, it still needs much more space than the Grower's Choice. According to some suggestions, that's roughly 18" above the canopy.

This could mean you'll need a proper cooling system, depending on set up.

Considerations for Choosing LED Growing Lights

Before you go out and buy grow lights there are some things you need to consider. The best grow lights for indoor plants may not work well for you.

Budget – The first thing to ask yourself is ‘What is my budget?’  While you can buy reasonably cheap led lights these days, it’s always recommended to buy the best you can afford. Don’t be tempted to buy the cheapest lights you can find. As with most things, you get what you pay for when it comes to cheap LED grow lights. That said, if you are on a tight budget, there are affordable grow lights that perform well. You can find our top 5 picks in their own section below.

Space – Plant LED lights come in a wide range of shapes and sizes. Obviously, it’s important to measure the surface area you want to cover with your lighting system. Don’t forget to measure the height you have available as well.

Plant Varieties – What are you going to grow? The LEDs you chose for general vegetable grow lights will not necessarily be the same as the best pot growing lights.

Growing Style – How are you going to grow your crops? Are you looking for the best hydroponic grow lights? Do you want the best grow lights for seedlings or flowering plants? Are you looking for the best LED for cannabis grown in the sea of green (SOG) style? The answers to your questions will result in different grow light options.

A Clear Winner - the Grower's Choice ROI E-680

For most cultivators, three categories make an LED grow light feasible: output, efficiency, and price. Other features and specs are helpful but don't ultimately sway the final purchasing decision.

It's the best bang per buck, with the highest output, industry-standard efficacy, and all for the lowest price point. Furthermore, it's affordability still comes with many (if not more) of the additional features you love to see in a grow light Including dimmers, uniformity of PAR, and the option of advanced controls.

The team behind the 'Grower's Choice ROI E-680 has figured out how to finally make a great product, at a reasonable price point. Growers buy based off results, and this fixture delivers far above its competition.
