GrowPros 4' Viper Under Canopy Grow Lights Model 4 - 150W Dual Channel 80% Red + White / Far Red (730nm)
GrowPros 4' Viper Under Canopy Grow Lights Model 4 - 150W Dual Channel 80% Red + White / Far Red (730nm)
Boost bud quality and increase yields by lighting up the lower canopy with a compact dual-channel system designed for deeper, more uniform flower development.
GrowPros Solutions' first-ever under-canopy lights with dual channels are 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. By targeting the understory, Growpros Solutions ensures a more uniform and abundant harvest, maximizing the potential of every plant.
Designed for aggressive flowering strategies, Viper UCL Model 4 delivers approximately 80 percent red spectrum on Channel 1, with an independent 730nm far red Channel 2. This setup activates the Emerson Effect, where deep red and far red light together increase photosynthetic efficiency beyond their individual impact. The result is improved light penetration, phytochrome shifting, and earlier bud set.

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.
