GrowPros Solutions Under Canopy 125 / 250 Watt Grow Light Full Spectrum + Far Red

The GrowPros Solutions Under Canopy Grow Light (4 ft R60) is a specialized horticultural lighting fixture designed to illuminate the lower canopy of plants where traditional top lights cannot reach. By delivering targeted light beneath dense plant foliage, this interlighting solution enhances the development of shaded leaves and lower buds, helping growers achieve more uniform plant growth and higher overall yields.

Engineered with an optimized full-spectrum output enhanced by deep red and far-red wavelengths, the fixture supports photosynthesis throughout the entire plant—from the top canopy down to lower bud sites. This balanced spectrum promotes improved flower density, color, and overall crop quality, making it suitable for both vegetative and flowering stages of growth.

Each 4-foot light bar operates at 125 watts and delivers approximately 325 µmol/s of PPF, providing strong light intensity in areas that are typically shaded. The system uses high-quality diodes, including white LEDs (around 4000K), 660 nm red LEDs, and far-red diodes, ensuring efficient light distribution and enhanced plant performance.

The slim single-bar design with a 120° lens angle ensures even light spread across the lower canopy while remaining compact and easy to install between plant rows or trellis layers. Its built-in driver, lightweight construction, and IP65-rated housing make the fixture durable and easy to maintain in humid grow environments.

Designed for commercial cultivation, the under-canopy lighting system supports power and data daisy-chaining, allowing multiple fixtures to be connected efficiently across large grow spaces. It is compatible with 120–277V power inputs and external lighting controllers, giving growers the ability to automate lighting schedules and optimize plant growth conditions.
