Top Features of the ROI-E420
Full Phase Spectrum
This fixture performs best using a 4ft x 4ft veg and 3.5ft x 3.5ft flower footprint, perfect for compact gardens and cultivation tents with a Recommended Hanging Height of between 6" and 24".
This fixture delivers the entire spectrum of light to your plants, giving them exactly what they need to grow big and beautiful. Grower's Choice famous GC-3K Full Phase Spectrum for will bring your plants to new heights with the best possible LED diodes available.
High Performance & Energy Savings
For growers with strict requirements on power, this fixture cranks out 1090 umols/s. At 420 Watts of power, that gives this system an PAR efficinecy of 2.6 umols/J. With dimming capabilities and a voltage range of 120 Volts - 277 Volts, you truly can find the perfect amount of power output and consumption. The ROI-E420 truly gives you a return on investment with up to 40% energy saving & 40% less HVAC requirement.
Compact Size
This fixture is approximately 3 ft in length (35.3") & width (34.6") making it a great fixture for 4' x 4' or 5' x 5' grow tents for the hobby grower and can even fold when not being used to reduce its storage size in half. Even with the compact size, the ROI-E420 still packs enough power to be used in commercial applications.
Onboard Dimming
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.
