The Grower's Choice ROI-420 LED grow light is inspired by a collaboration between two of the most prominent and respected companies in the indoor grow lighting industry: TSL Horti Tech and Growers Choice.
These two brands have come together to combine their years of experience and innovation in grow lighting to create this high performance, cost effective, efficient lighting solution for commercial growing.
ROI-E420 LED Grow Light Features
Highly efficient: 1090 umol/s total output while using only 420w (2.6 umol/j efficacy)
Large coverage area: 3.5'x3.5' for bloom and 4'x4' for veg
Great spectrum: 3000k full-spectrum white plus 660nm deep red (Osram diodes)
Dimmable: dim from 0 to 10v to save on power when full output is not needed
- Remote operation: control multiple lights with Grower's Choice Master Lighting controller (choose the add-on above)
- Great light distribution: multiple bar light configuration makes for a more even light distribution
Fanless design: bar light design also means fans are not required to deal with heat
Rated for commercial use: IP65 waterproof plus UL8800, UL1598, DLC and CE certification
5 Year warranty
Great Spectrum For All Stages Of Growth
The ROI-E420 has the same 3000K full-white spectrum as Grower's Choice's well known 3K CMH Full Phase Spectrum. This light provides excellent growing power and monster yields.
Huge Output, High Efficiency
This powerful LED grow light provides 1090 μmol/s of total output, and with a wattage draw of 420 watts, it has a 2.6 μmol/J system efficacy.
This means up to 40% savings on electricity costs. Lower heat output additionally cuts cooling requirements by about 40%.
Provides Growers Full Control
The onboard dimming function allows you to dial back the intensity at times when your plants don't need the full power of this light, saving you money on electricity costs.
The ROI-E420 is compatible with most lighting controllers, but works best with the Grower's Choice Master Lighting Controller (which you can purchase with the fixture by selecting the option above, directly beneath the price).
Even Light Distribution
The large size of the Growers Choice ROI-E420 LED grow light makes for a much more even light distribution, because the light from the fixture always travels the same distance downward toward the canopy.
A small fixture sends light from a central point, which means it travels much further to reach the corners, and loses intensity along the way.
Growers Choice and TSL Horti Tech wanted to make sure only the best components went into their light, so they used industrial grade Osram Top Bin Diodes and an ultra-efficient driver when designing this fixture.
