The GrowPros Solutions COBRA Under Canopy Light – Model 3 is a high-performance dual-channel interlighting system designed to deliver targeted light beneath dense plant canopies. Installed below the top foliage, the fixture ensures that shaded leaves and lower bud sites receive sufficient light, improving plant uniformity, enhancing flower density, and increasing overall crop yield.

This advanced under-canopy lighting solution features two independently controllable spectrum channels that allow growers to tailor the light recipe for different growth stages. Channel 1 combines UVA, blue light, and 5000K white spectrum, supporting vigorous vegetative growth, improved plant structure, and enhanced resin development. Channel 2 delivers deep red, far-red, and warm 3000K white light, which promotes flowering, bud development, and higher biomass production.

The COBRA Model 3 is available in two sizes—4 ft and 8 ft—to accommodate different grow layouts and canopy widths. The 4-foot model operates at approximately 150W (75W per channel) and delivers around 450 µmol/s of PPF, making it ideal for single bench rows or compact grow spaces.
For larger installations, the 8-foot model provides about 300W total output (150W per channel), offering wider coverage and stronger photon delivery to deeper canopy layers.

Designed with a slim aluminum housing, built-in driver, and passive cooling system, the fixture produces minimal heat while maintaining reliable long-term performance. Its IP65-rated waterproof construction ensures durability in humid grow environments. The light also supports RJ12 data connectivity and 0–10V dimming, enabling integration with lighting controllers and allowing growers to automate light intensity and spectrum management.

With power and data daisy-chain capability, multiple fixtures can be connected easily across large grow rooms, vertical farming systems, or greenhouse benches. The COBRA under-canopy lighting system helps transform shaded lower canopy zones into productive flowering areas, improving overall crop quality and harvest consistency.
