Catalyst® GH
Designed for high-voltage greenhouses—including 480V—Catalyst® GH is ideal for large-scale operations. By delivering light from below, Catalyst® GH compensates for canopy shadows, promoting healthier lower growth and higher-quality flower. With flexible mounting options like stands, sliding mounts, and custom configurations, Catalyst® GH adapts to any facility layout.
Growers can expect up to a 40% increase in premium flower.

Mounting Options
We offer various mounting configurations to fit the needs of your greenhouse. We also offer the Catalyst® Mobile, featuring custom mounts specifically designed for Mobile Grow Tables and Containers in high voltage greenhouses.
Sliding Mounts
Sliding Mounts are adjustable in length to
easily mount onto trellis bars.
Stands
Lightweight, durable stands that mount directly
to the bottom of the Catalyst and your grow table.
One system, flexible power and layout configurations.

Key Benefits
Increase Yields Up to 40%
Early adopters report 20–40% yield increases by delivering more light beneath the canopy.
Safe for High Voltage
Operates safely from 208–480 VAC via remote driver, while delivering safe low-voltage DC near plants.
Stationary, Easy to Work Around
Lights remain in place for quick room turnovers and minimal wear.
Greenhouse-Optimized Spectrum
Broad-spectrum light with 52% red, 17% blue, 29% green, and 2% far red to maximize growth.
Custom Power Configurations
Whether your grow calls for a single high-power fixture running down the center or dual-row medium-power units for wider coverage, we can configure the system to match your exact needs.
