Yr. Warranty

PHOTOBIO Multibar MX 680W LED grow lights change everything. We took a step back, evaluated all the fixtures on the market, and then set out to do things entirely different. Thus, we give you an LED grow light fixture delivering 15% more light to your canopy using 35% less power than a 1000W DE fixture. Therefore, you increase yields while driving down operational costs. The MX 680W LED grow light spectrums were developed in a private research laboratory to drive flower yield and elicit market desirable traits in short day resin producing crops.

In favor of a more efficient contiguous circuit board to deliver unparalleled PPFD uniformity to the plant canopy, the MX 680W LED abandons the bar-style grow light concept. Extensive thermal modeling and testing was conducted to ensure diodes remain well below operating temperature to maintain consistent light output and yields. The 0-10V PHOTO•LOC Light Output Control allows you to precisely regulate the amount of light delivered to the canopy when paired with the available Autopilot PX Series controller.

iLOC Integrated Light Output Control on board dimming knob allows you to adjust the photon output intensity to accommodate the various stages of plant growth for optimal photosynthesis activation. With the knob adjusted to 100% using 240V, the MX uses 664W and puts out 1700 μmol/s photon flux (PPF). When the knob is adjusted to 40%, the MX uses 270W and puts out 40% of the photon flux. High efficiency S4 spectrum does not change when using the dimmer knob. It still provides ideal red to blue ratio for vigorous growth and maximized flower development.

Extraordinary performance. Extreme efficiency. Exacting design.

PHOTOBIO Multibar MX 680W LED grow lights have a multilayer rack centric design, providing the ability to double or triple your canopy square footage within your existing structures footprint. Because the driver is mounted below the fixture and can be remotely mounted, vertical grow space is maximized.

This commercial LED grow light is designed for the serious horticultural professional who is looking to increase business sustainability by reducing power consumption and, simultaneously, improving crop performance and yield. The PHOTOBIO MX 680W Multibar LED grow light is also a qualified product listed with DLC, which makes the fixture eligible for energy rebates, thus giving you futher cost savings and saving significant energy while optimizing plant growth and health.
