Excalibur King Series by Grow-it-LED is a commercial LED grow light designed for 1000w DE HPS replacement. They designed this system to outperform the competition at an extremely competitive price. The Excalibur King Series offers multiple spectrum packages at various price points to offer tiered pricing and spectrum options. The fixture design offers a completely silent operation due to its passively cooled design. Each LED is under-driven for increased efficiency and longevity. 100,000h should be expected from this system. It offers quite a few spectrum options for this grow light to give you some flexibility with your grow.
Each spectrum is an excellent option in its own regard. The lowest priced option can easily replace a 1000w HPS grow light and still produce a product that is far better than that of an HPS product. While their highest priced UV to IR grow light utilizes new technology to leverage growing techniques such as the Emerson effect for quicker flowering times. UV is also an excellent addition due to its known properties for increasing oil production and terpene profiles.
All fixtures come with a wireless control option, the Casambi system can control each fixture individually. This allows for DLI control, sunrise/sunset functions, and spectrum tuning. Casambi can be used on Apple or Android devices.
Wireless Casambi control is available for this product along with the Aegis Series, Cool Cob Series and Excalibur Series.
