The Pro Grow LED 630W is an energy-efficient alternative to HID fixtures, delivering a 25% increase in grams per Watt compared to traditional 600W HPS lamps. With a high CRI of 91.1, it enhances terpene profiles through increased full spectrum light intensity while minimizing heat. Featuring top bin SMD diodes from Samsung and Osram, it achieves an outstanding efficacy of over 2.73 μmols/s and an industry-leading PPF of 1,720 μmols/s. The 630W emits a 4,000 Kelvin full spectrum light with a CRI of 90, and its durable design includes a fanless, silent operation and IP-55 water resistance. The fixtures are dimmable via the driver dial, and extended reliability is ensured with cleanable housings. The 630W models come with four mounting rope ratchets.
