Grow-It-LED Excalibur King Series 740W Full Spectrum LED Grow Light

The experts at Grow-it-LED have designed the Excalibur King Series 740 Watt Full Spectrum LED Grow Light to consistently outperforms the competition while maintaining an extremely competitive price. This commercial grade LED grow light can easily replace a DE HPS fixture up to 1000 watts. Excalibur King series LED grow lights offer multiple spectrum options, allowing you to have excellent flexibility for your indoor garden or grow operation.

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.

Full Spectrum Control

The Excalibur King 740w gives you full spectrum control at a very affordable price.
I purchased this light with the S3 Samsung L09 and L2 Horticulture Blended Spectrum.
Grow-it-LED paired the LED boards with Osram LED drivers and a Casambi wireless controller.
The Casambi gives you more features than a $500 master controller for $50 and is all controlled by a Bluetooth smart phone app.
The fixture housing it’s made out of aluminum so it’s fairly light but built like a tank.
I really love the fact that each LED bar is replaceable/upgradable and has its own driver. No total loss of light in the case of a failure. I was worried about heat in a 4 x 4 tent but it does not seem to be a problem.
My plants responded positively after introducing them to the new light and have shown positive improvement since I adjusted the spectrum.
This is an awesome LED built in the USA by a family owned company, so sweet!
