GrowPros Solutions Under Canopy 125 / 250 Watt Grow Light 80% Deep Red Spectrum

The GrowPros Solutions Under Canopy Grow Light R80 (4 ft) is a specialized interlighting fixture designed to deliver powerful illumination to the lower canopy of dense plant structures. Installed beneath the plant canopy, this light ensures that shaded leaves and lower bud sites receive the photons needed for healthy development, resulting in more uniform plant growth, improved flower density, and increased overall yield.

Engineered with a high-intensity spectrum containing approximately 80% 660 nm deep-red light, the fixture is optimized for flowering performance and canopy penetration. The spectrum is complemented with a refined blend of blue, warm white (around 3000K–4000K), and 730 nm far-red wavelengths, helping enhance photosynthesis, improve bud formation, and support balanced plant growth throughout the canopy layers.

Each 4-foot light bar operates at approximately 125 watts and produces up to about 325–350 µmol/s of PPF, delivering strong light intensity directly to areas that are typically underlit in traditional top-lighting setups. This targeted lighting strategy helps stimulate lower flower sites, boost terpene and resin production, and increase harvest quality.

The fixture features a slim single-bar aluminum design with a 120° lens angle, providing wide and even light distribution across the lower canopy while remaining compact and easy to install between plant rows or grow benches. Built with IP65 waterproof protection, passive cooling, and a built-in driver, the light is engineered to operate reliably in humid indoor cultivation environments.

Designed for professional cultivation, the system supports 0–10V dimming and RJ12 controller connectivity, allowing growers to automate lighting intensity and integrate multiple fixtures through power and data daisy-chain connections for large-scale grow facilities.
