Description

The ROI-E420 is the perfect balance between energy efficiency and performance

From the minds of both Grower's Choice & TSL Horti Tech, the same pair that brought out the ROI-E680, one of the best LED Grow Lights in the industry. Introducing the ROI-E420 full-spectrum, compact horticulture LED fixture. Utilizing Grower's Choice proven 3K full PAR spectrum, this LED is perfect for professional cultivators and grow enthusiasts alike, who require a powerful LED fixture with a lower profile frame. This new, sleek LED is also perfect for hobby growers or entry-level professional cultivators who want to maximize their yields while working with limited space.

Top Features of the ROI-E420

Full Phase Spectrum

All Growers Choice LEDs use Osram Top Bin Diodes

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 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 a PAR efficiency 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 intensity 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 controllers 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 an HVAC failure, potentially saving gardens from heat damage.

 

 

Growers Choice Master Lighting Controller

Grower’s Choice digital lighting controller enables the grower to control up to 200 fixtures. It is compatible with all GC-315 CMH, GC-630NS CMH, GC-1000 DE fixtures, ROI-E420 & ROI-E680 LED grow light.

This dual-channel controller allows daisy chaining up to 100 fixtures per zone. En-abling complete control of your growing environment with timed on/off switching, sunrise/sunset, and precise temperature readings with dual thermal probes and thermal-threshold auto dim-shutdown for additional protection.
