Add deep red spectrum under your canopy to boost bud density, and total yield with this high-efficiency 250W LED fixture.
The Grow Pros Solutions 8' under canopy light red spectrum version 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.
Engineered with approximately 80 percent 660nm deep red, paired with a refined blend of pure blue for improved color expression, 3000K warm white, and 730nm far red. This UCL Model 2 spectrum enhances canopy penetration, improves bud density, and supports more uniform development across plant layers.
Maximize Flowering and Concentration
Under canopy lights are designed to illuminate beneath the dense plant canopies where traditional overhead lights struggle to reach. This strategic lighting approach not only boosts the yield but also enhances the quality of your crops by:
Increasing Flowering: By providing essential light to lower canopy areas, these lights promote more extensive flowering even in the shaded parts of the plant.
Enhancing Concentration: The added light spectrum encourages terpene compounds, improving the potency and profile of your harvest.
Spectrum Balancing for Optimal Growth
To achieve these benefits, it’s crucial to select the right spectrum based on your existing setup:
- Model 1 Lights: Ideal for complementing HID top lights, which are rich in ROY (red, orange, yellow) spectrums.
- Model 2 Lights: Best paired with full-spectrum LED top lights to ensure comprehensive coverage.
This customization allows growers to balance light spectrums effectively, ensuring that every plant receives the optimal wavelengths necessary for peak growth and quality. By integrating these advanced lighting solutions, you can achieve increased yields and superior product quality, setting your harvest apart in appearance and chemical composition.

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.
