Choose the installation configuration

The linear format can be positioned for crop-side interlighting, undercanopy supplementation or overhead use. Select compatible mounting hardware, power connections and controls for your layout. Power connections, stands and controls must be checked separately; this is a fixture listing, not a trial kit. Electrical loading and the permitted number of interconnected fixtures depend on input voltage, wiring and installation. Have a qualified electrician verify the system before use.
