Both the Growers Choice ROI-E720 and ECO Farm MB3 Pro 760W LM301B LED are among the top models in the industry for maximizing PAR efficiency, with the ROI-E720 coming in at 2.6 umols/J and the ECO Farm MB3 Pro 760W LM301B LED at 2.8 umols/J. How do they stack up to each other?
Growers Choice ROI-E720 LED Grow Light
The ROI-E720 is a user friendly commercial grade fixture. However, Grower’s Choice does not recommend the E720 for inexperienced growers or tent applications. The E720 is designed as a high output fixture for commercial cultivation's, emitting nearly the same PPF as a standard 1000w DE HPS fixture and lamp. With intense PPF, 3k full phase spectrum and balanced PPFD the ROI-E720 has the potential to produce the highest yields and superior quality. GC highly recommends this fixture be used in professional, environmentally controlled cultivation’s that supplement CO2. Without using CO2 the grower may be introducing more light than the plants can process, possibly causing stunted growth or light damage. Know your garden and provide light accordingly.
The 720 increases the wattage from 680 to 720 and includes newer improvements to LED technology. The ROI can also be used in the BOOST mode to increase the PPF of 1870 umol/s to 2050 umol/s (approximately 10%). The ROI-E720 is designed to be slightly more of a replacement for 1000w HPS lights in indoor grow rooms with taller ceilings. If you're growing in a room with lower ceiling height, or in a multi-tiered fashion, it may make sense to use the ROI-E680 instead so you can get closer to the plants without overpowering them with intensity.
You can set the ideal intesity at any time for optimal plant growth without the use of an external controller. If you prefer an external controller, no problem. This fixture is compatible with most lighting contollers including Growers Choice Master Lighting Controller. With the GC master controller, cultivators can set the fixture to turn off and on at desired times, program sunrise/sunset settings, program dimming options and set protective fail safes to dim or turn off fixtures in the event of excessive room temperatures, such as in the event of HVAC failure, potentially saving gardens from heat damage.
ECO Farm MB3 Pro 760W LM301B LED Grow Light
5 Memory Timing Functions: Designed with a periodic auto cycle ON/OFF memory timing function, stay on for 6/8/12/14/16 hours, then auto turn off for 18/16/12/10/8 hours, auto ON/OFF at the same time daily , No need to restart manually. Within 30 minutes of timing ON/OFF, it will simulate the light gradual effect of the sun rising or setting process. Reduce the wastage of forgetting to turn off the lights and your working time.
HD Digital Screen: Adopts the latest high-definition energy parameter screen design, which clearly displays the timing, PPF, electric power and light intensity. Understand the needs of plants in each growth stage, make plants better absorb sufficient energy, help you become an experienced planting expert and achieve surprisingly high yields.
Dimmable Commercial Daisy Chain: Support 0-10V dimming, turning the knob can adjust the brightness of 40%/60%/80%/100%, and also support the conversion of V1/F1 spectrum. The daisy chain function can connect up to 50 LED plant growth lights, which are widely used in commercial planting (horizontal and vertical), climate rooms, home gardens, home planting (planting boxes and tents), greenhouse cultivation, pipeline cultivation, and hydroponics.
Take a look at the following table, which closely compares the specifications of the Growers Choice and ECO Farm LED lights.
LED Specs Compared
Discussion: There are several specs, in addition to PAR intensity and spectrum, that vary significantly between these two LED brands and can affect a buyer’s decision.
The ECO Farm MB3 Pro 760W LM301B LED produces a considerably higher PAR intensity of 2128μmol/s over the Growers Choice LED of 1924 μmol/s, enabling the ECO Farm LED to cover a larger grow area: 6’ x 6’ instead of only 5’ x 5’. The ECO Farm LED, on the other hand, produces a slightly better PAR efficiency of 2.8 umols/J while the Growers Choice PAR efficiency is 2.6 umols/J.
Growers Choice LED manufactures a controller that can be used to program DLI, dimmability and fail safe responses of up to 200 lights together.ECO Farm offers a controller only for dimming 50 lights.
ECO Farm produces an LED model that accepts higher voltage inputs (347–480v); the Growers Choice brand does not. The ECO Farm MB3 Pro 760W also is considerably lighter, weighing just 30.86lbs.
Spectrum Differences

Discussion: ECO Farm MB3 Pro 760W LM301B LED has two spectrums： V1 Full spectrum (380-410nm, 660-665nm, 730nm, 3200-4200K, 4800-5000K) is perfect for all growth stages. ECO Farm Led grow light adopts advanced design F1 exclusive bloom spectrum to speed up photosynthesis of plants in flowering and fruit stages function, shorten the growth cycle and increase yield. Bring you a better harvest in a shorter time.
Despite these differences, we consider both LEDs equally matched in spectral quality, since each utilizes the latest in LED technology required for maximizing potential yields.Neither LED produces UV or IR radiation, so crop quality can be further improved by incorporating supplemental lighting to these spectrums. Both LEDs will look white to the human eye, with little sprinkles of red diodes. These LEDs do not come off looking red and blue as old LEDs did.

There are many things to consider when purchasing a LED grow light. The coverage area and light distance will help narrow down your search results and ensure your grow space is appropriately covered. PAR output is measured in different ways and misinformation about intensity is very common. The light spectrum that the LED grow light emits is important since cannabis has different needs throughout its life. Also, an even light spread will help with growth across the entire plant. Wattage is often confused for light intensity instead of what it actually is – energy consumption. It’s better to go with high-quality diodes and efficient drivers from trusted manufacturers instead of going with unknown brands. Lastly, the warranty that the LED grow light has will offer you protection in case the light becomes defective. Considering these things prior to buying a LED grow light will help ensure your money is being well-spent.
