Main Features of ROI-E420 Grow Light
Full Phase Spectrum
This fixture provides your plants with the whole spectrum of light, giving them everything they need to grow big and beautiful. Grower's Choice's renowned GC-3K Full Phase Spectrum will propel your plants to new heights by utilising the best-LED diodes available.
High Efficiency & Energy Savings
This fixture produces 1090 umols/s, which is ideal for growers who have stringent power requirements. With 420 Watts of power, this system has a PAR efficiency of 2.6 umols/J. You can select the ideal quantity of power production and consumption with dimming capabilities and a voltage range of 120 Volts - 277 Volts. The ROI-E420 genuinely provides a return on investment with up to 40% energy savings and 40% reduced HVAC requirement.
Compact and Small Size
This fixture is roughly 3 ft in length (35.3") and width (34.6"), making it a fantastic fixture for 4' x 4' or 5' x 5' grow tents for the hobby grower. It can also fold when not in use, reducing its storage size in half. Despite its small size, the ROI-E420 has adequate power to be employed in commercial applications.
Onboard Dimming
Without the use of an external controller, you may set the right intensity at any time for optimal plant growth. No problem if you prefer an external controller. Most lighting controllers, including the Growers Choice Master Lighting Controller, are compatible with this fixture. Cultivators can use the GC master controller to programme the fixture to turn on and off at specific times, programme sunrise/sunset settings, programme dimming options, and set protective fail safes to dim or turn off fixtures in the event of excessive room temperatures, such as an HVAC failure, potentially saving gardens from heat damage.
Master Lighting Controller by Growers Choice
The Farmer's Choice Master Lighting Controller digital lighting controller allows the grower to operate up to 200 fixtures. It works with all GC-315 CMH, GC-630NS CMH, GC-1000 DE fixtures, as well as the ROI-E420 and ROI-E680 LED grow lights.
This dual-channel controller supports up to 100 fixtures per zone. With time on/off switching, sunrise/sunset, and exact temperature measurements with dual thermal probes and thermal-threshold auto dim-shutdown for added protection, you have complete control over your growing environment.
