Excalibur 680X Series Product Description

We’ve evolved our Excalibur King LED fixtures into the Excalibur 680X LED Grow Light. Moreover, the Excalibur 680X represents a foldable LED grow light that requires minimal assembly. Our Excalibur Series incorporates Samsung’s state-of-the-art LED technology, which utilizes robust heatsinks for passive cooling. We provide a variety of spectrum options for these fixtures, tailored to both price and efficiency (feel free to contact us for custom choices!). We select Inventronics drivers and pair them with Samsung’s finest LED technology, making them our exclusive preference for LED drivers. Their exceptional efficiency and remarkably low failure rates ensure uninterrupted operation with no maintenance costs.

Innovative Reflector Technology

We take pride in introducing TRUE reflectors on our Excalibur X and C series fixtures. These reflectors, with their revolutionary performance and innovative design, provide a 10 to 15% increase in PPFD efficiency. Our PPFD readings clearly demonstrate the results. This fixture sets the benchmark as the highest-performing 680W fixture available on the market!
