Light up the entire canopy from top to bottom with this 8ft dual-channel fixture that boosts both veg and flower performance using UVA, blue, red, and far-red.
The GrowPros Solutions 8ft Under Canopy Light Model 3 is designed to provide supplemental light to the lower regions of plants in indoor cultivation environments by strategically placing them beneath the top canopy of plants to ensure leaves and flowers below the canopy receive optimal light exposure by eliminating shady areas. Under Canopy Grow Lights, benefits include uniform light distribution, maximized yield, and denser flowers.
GrowPros Solutions' first-ever under-canopy grow lights dual channel is engineered to enhance the yield and color of lower flowers. These supplemental lights can significantly enlarge B-buds and C-buds, promoting better growth and development in areas that typically underperform.
Built with premium housing and glass lenses, the Cobra UCL Model 3 is a dual-channel LED grow light designed for growers who want full control. One channel focuses on UV and blue wavelengths to drive resin production and quality, while the second channel emphasizes red spectrum output for yield. This flexibility makes it ideal for craft operations aiming to fine-tune plant response through each stage.

Interconnect Cables and Power Cords
Grow Pros Solutions Under Canopy Lights do not include a power cord. Each lighting run requires at least one Under Canopy Light Power Cord 240V with Attached Data Cable to connect the first fixture to a power source and enable data communication. Additional fixtures can then be connected using the Under Canopy Light Interconnect Cable, which carries both power and data between lights.
Interconnect cables are not required when mounting lights end-to-end. They are only needed to bridge gaps of up to 4 feet between fixtures or to create a U-shaped layout with two rows of lights on a single bench.
Refer to the daisy-chain chart below for the maximum number of fixtures that can be connected to a single power cord based on your operating voltage.
