Grow-It-LED Excalibur King Series 740W Veg LED Grow Light

The Excalibur King Series 740 watt LED Grow Light is the industry's best value in a high intensity full spectrum light. With 740 watts of LED power, you'll notice an improvement in your plants' overall health and vigor. Excalibur King series LED grow lights offer multiple spectrum options, allowing you to have excellent flexibility for your indoor garden or grow operation. These lights will pay for themselves many times over with increased efficiency and plant growth.

The Excalibur King Series comes in the spectrum packages you need to offer both tiered pricing and spectrum options. These are some of the best LED grow lights on the market, featuring a passively cooled design that provides completely silent operation. Each LED is under-driven for increased efficiency and longevity so you can expect 100,000 hours of life from this system.

Each spectrum is itself an excellent option, depending on your specific needs. Even the lowest priced option can easily replace a 1000w HPS grow light and still produce a product that is far better than anything you’ll get from an HPS fixture. UV to IR grow lights utilize 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 are compatible with the optional Casambi wireless controller, giving you the ability to control DLI, sunrise/sunset functions, and spectrum tuning for each fixture individually. The Casambi system can be used on Apple or Android devices.
