The Excalibur 680XT 8 Array offers a distributed array configuration specifically designed for grow tents. The 680XT 8 Array increases the overall average PPFD you would expect from a bar style grow light by shifting the arrays towards each side of the fixture. This allows for the best coverage possible by while being ultra efficient!
The Excalibur 680XT 8 Array showcases the most cutting-edge LED technology from Ledestar. Passively cooled with a robust heatsinks for an incredibly long lifetime. Pared with the best Ledestar LED technology, Inventronics drivers are our sole choice for LED drivers. High efficiency and incredibly low failure rates ensure constant uptime with zero maintenance costs.
We are proud to offer TRUE reflectors on our Excalibur X and C series fixtures. These reflectors offer 10 to 15% increase in PPFD efficiency due to their revolutionary performance and innovative design. Our PPFD readings speak for themselves! This is the highest performing 320w fixture on the market!
Our latest boards are conformal coated to help withstand the harsh environments that are commonly associated with indoor horticulture applications. Conformal coating ensures that each board will maintain its rated lifetime and be protected from intrusion from water, foliar spray, and other liquids that may come into contact with the diodes.
Our fixtures are designed for harsh environments where plastic just wont make the cut! We designed these fixtures to be incredibly robust and opting for a 100% aluminum construction not only for increased fixture performance but for a long lasting, corrosion resistant, American Aluminum housing. We designed this housing to help reduce the junciton temperature of the diodes for an long lasting lumen maintenance (lighting industry term for how long the fixture will output light without degrading). This translates into a fixture that will maintain its output for a much longer time vs our competitors.
Our brand new Hotri-Centric spectrum offers top tier performance compared to our competition. We designed this spectrum over years of testing to ensure our customers will producing high yields and quality flowers run after run. Utilizing dual-blue LED phosphors, we can proudly state we manage to achieve a PPF efficacy of 2.98 umol/J and an ePAR efficacy of 3.05 umol/J!
Our specially designed heatsinks offer top notch thermal performance compared to our competition. Standard heatsinks on other commercial grow lights rely solely on passive cooling with a large surface area. Our heatsinks with open obround design, allows for natural convection to occur. When the heatsink warms up to operating temperature, the natural convection action from the heat being produced pulls cooler air through the strategically placed holes to further increase the cooling performance of the heatsink itself.
Not only are the LED boards conformal coated but the entire housing is protected from water intrusion! We use special IP67 connectors, IP67 Drivers, and Conformal coated LED Boards, resulting in a combined rating of IP65. Never worry about getting you LED fixtures wet again!
Our 680XT 8 Array is specifically designed to fit snuggly inside of a 4×4 grow tent and provide your plants with a more even PPFD across the canopy. By shifting the arrays towards the edges of your tent, we have successfully increased the average PPFD levels across the canopy. This distributed light source coupled with our innovative reflector design drastically increases the overall efficacy of the fixtures by a substantial amount! See our PPFD comparison below:
Control the Excalibur series with our GIL100 Touch Screen Controller or if you already are using another controller, enjoy complete compatibility with other industry leading control systems through the integrated RJ14 port! The Excalibur Series also comes standard with a Dimmer Knob for fixture output control right out of the box.
