The Growers Choice ROI-420 LED grow light is a high performance and cost-effective lighting solution for commercial and home horticulture. The powerful ROI-E420 LED grow light optimizes plant growth at all stages, from seedling to vegetative growth. Suitable for large indoor grow space, the full spectrum ROI-E420 meets all demands of growers looking for a natural light spectrum, while consuming less energy and reducing operating costs.
High Efficiency: With a total output of 1090 μmol/s and a wattage draw of 420 watts, the ROI-E420 has a 2.6 μmol/J system efficacy. So you save about 40% on electricity costs compared to HID. Additionally, lower heat output cuts cooling requirements by up to 40%.
Provides Full Control: The onboard dimming function lets you adjust the light output down from 0-10V when plants don’t need the full power, cutting down on your electricity costs.
Even Light Distribution: Because of the large 4-bar design size, the light from the fixture travels evenly across the grow space, without losing intensity.
