Growers Choice ROI-E420 LED Horticultural Lighting Fixture
$699.00
The specially deployed GC-3K full phase spectrum fills the lack of the main photoreceptors and pigments outside the 660-450nm range. The GC 3k spectrum is very close to natural sunlight. The modest blues, extra red, and UV light exceed the photosynthetic needs of your plants during the flowering phase and increase the yields.
Due to the 4-bar design and a small fixture that sends light from the center, the light travels at the same distance to reach all corners. The manufacturer recommends the ROI-E420 for a 3’x3′ to 4’x4′ footprint, hanging at a distance of 8” above the canopy. For larger grow space and if your plants are in the vegetation stage, you can hang it 6-24” above the canopy.
This LED grow light features top bin OSRAM diodes that are considered the best diodes in the industry. These diodes have an incredible lifespan of 54,000 hours. Some of these diodes are 660nm, which is extremely beneficial for flowering. The grow light is passively cooled, so there are no active cooling fans consuming extra wattage.
You can use it with the Grower’s Choice Master Lighting controller for better control over a timed on/off, sunrise/sunset, and temperature readings.
The ROI-E420 LED grow light has several safety certifications, including ETL, CE certification, and IP65 waterproof. Also, the light comes with a 3-year factory warranty from Grower’s Choice.
