HID Grow Light Controllers
HID grow light controllers manage multiple HPS or MH ballasts from a single control unit -- simplifying the electrical infrastructure of large grow rooms where running individual timers to each ballast is impractical. Multi-light controllers in this collection from Autopilot, California Lightworks, Growers Choice, and FloraFlex provide centralized on/off scheduling, in some cases 0-10V dimming output, and surge protection for the connected ballast circuits. A single 8-light controller replaces eight individual outlet timers while also providing more reliable ballast protection than a standard power strip setup.
Autopilot PX2 and Multi-Light Controllers
The Autopilot PX2 Advanced Digital Lighting Controller manages multiple HID ballasts from a single programmable digital unit with independent circuit control and protection. Multi-light controllers from Titan Controls and Autopilot in the 4, 8, and 16-light formats are the standard for commercial HID rooms where the number of ballasts makes individual timer management impractical. Each outlet on a multi-light controller is typically rated for one ballast at the appropriate wattage and voltage; verify per-outlet wattage ratings match your ballast specifications before connecting.
LED Dimming Controllers
California Lightworks SolarSystem Lighting Controller and Growers Choice Master Lighting Controller provide programmable spectrum and intensity control for compatible LED fixtures with 0-10V inputs. FloraFlex LED controllers manage compatible FloraFlex fixtures. For complete environment and lighting integration, see TrolMaster Hydro-X and all environment controllers.

HID Lighting Controllers FAQ
What is a multi-light controller and why use one?
A multi-light controller is a centralized electrical panel that provides timed switching and surge protection for multiple HID ballasts from a single unit. Instead of plugging each ballast into a separate timer outlet, all ballasts connect to the controller, which manages the on/off schedule for the entire room simultaneously. Benefits include: simplified wiring (one timer to program rather than many), surge protection across all ballast circuits from a single point, and in commercial systems the ability to add load management features (staggered startup delays that prevent simultaneous inrush current from all ballasts at lights-on). A properly specced controller also provides better electrical protection for expensive ballasts than generic power strips.
Can I use an HID controller for LED grow lights?
Standard HID multi-light controllers manage on/off switching for any connected load -- they will physically switch LED fixtures on and off on the programmed schedule. However, HID controllers do not provide 0-10V dimming output, which is required for LED intensity control. For LED operations, use an environment controller with 0-10V output (TrolMaster Hydro-X, California Lightworks SolarSystem controller) or the LED brand's specific controller accessory to manage dimming alongside on/off scheduling. Using an HID-style controller with LEDs is functionally acceptable for basic on/off scheduling but does not unlock the intensity management and spectrum control that are primary advantages of modern commercial LED systems.
How many ballasts can I connect to a multi-light controller?
Each lighting controller has a rated maximum circuit count and per-circuit amperage rating. A 1000W 240V ballast draws approximately 5A; an 8-circuit controller at 240V can handle 8 x 1000W ballasts if each outlet is rated at 5A or more. Verify the total load does not exceed the controller's main panel rating -- an 8-outlet controller at 240V with a 50A main breaker handles up to 12,000W total (50A x 240V), but individual outlet protection limits per-outlet load. For large commercial rooms with many fixtures, contact 888-815-9763 to discuss appropriate controller sizing and electrical configuration for your facility.
