Operating at 645 watts with an output of 1700 µmol s-1, this fixture achieves an impressive efficacy of 2.6 µmol s-1 per watt. Eight passively cooled LED bars provide intense light coverage with no fans or moving parts—significantly reducing the number of possible fail points compared to other fixtures. The Gavita Pro 1700e LED is dimmable and distributes broad, full-spectrum light anywhere from 50% to 100% while maintaining efficiency. Dim using the Gavita E-Series LED Adapter and Gavita EL Master Controller to create ideal lighting levels as needs change from veg to bloom for various crops throughout their growth cycles. The Gavita E-Series LED Adapter – 120-277 V (sold separately) is required for each fixture when using the controller; non-controlled fixtures simply operate at 100%. You can connect up to 500 – 1,000 LED fixtures, depending on the controller, using a setup with daisy-chained splitters. IP66 wet rated and UL8800 compliant (IP56 wet rated and CE/CB compliant in EU) for use in wet environments which allows versatile placement in growing spaces. Its wet rating provides complete protection from dust, oil and water, allowing you to mount this light source in low rooms, on vertical racks, over rolling benches or even in tents. The 8-bar configuration allows you to mount this light source in low rooms, on vertical racks, over rolling benches or even in tents. For maximum uniformity, hang the fixture 24-36 inches from the crop. Reliably sourced components including Philips AdvanceDrivers, Samsung white LEDs and Osram deep-red LEDs create improved performance. The Gavita 1700e gently drives LEDs to optimize fixture life and improve spectral output. The 8 passively cooled bars provide full-spectrum, broad-coverage light for full-term growth.
