Group Control Lighting Adapter, for 0-10V protocol

What the LMA-14G Is

The TrolMaster LMA-14G is a Group Control Lighting Adapter designed for operations running multiple independent lighting zones under a single TrolMaster environmental controller. It accepts a 12V input from the controller and outputs an analog 0-10V signal that translates the Hydro-X system's digital scheduling and dimming commands into the low-voltage signal your fixture's driver expects.

Where the standard LMA-14 adapter handles a fleet of lights on a shared schedule, the LMA-14G adds zone-level granularity: each adapter is assigned its own schedule group via the onboard LCD, so different rooms, benches, or cultivation stages can run different photoperiods and intensity ramps — all managed from one Hydro-X Pro or Hydro-X Plus controller. Connection to the controller is via RJ12 cable for a clean, plug-and-play install with no custom wiring at the controller end.

Who It's For

The LMA-14G is the right adapter for licensed cannabis and hemp facilities that need zone-differentiated lighting control: think a veg room and a bloom room on separate photoperiods, a propagation bench on a third schedule, or any multi-stage layout where a single shared schedule would be a bottleneck. It's also the right call for retrofits — if your facility already runs TrolMaster Hydro-X Pro or Plus and you're adding a new zone or canopy area, one LMA-14G per new group is all you need to bring those fixtures into the existing controller ecosystem.

Because it's designed for most horticultural lighting fixtures with a standard 0-10V dimming input — including a wide range of commercial LED drivers and HID ballasts — the LMA-14G works across common fixture platforms without requiring a proprietary cable set or brand-specific firmware.

Key Features

Group addressing via onboard LCD: each LMA-14G is assigned its own group ID, giving the Hydro-X Pro or Plus controller distinct scheduling and dimming lanes per adapter. This is the core differentiator from the standard LMA-14, which does not provide independent group assignments.

Pigtail wiring connects the adapter directly to your light drivers — no breakout box or additional cable set required. The RJ12 port on the controller side gives a secure, indexed connection that won't back out during normal facility operation. The adapter operates across a working environment of 32–122°F (0–50°C) at up to 90% relative humidity, appropriate for the temperature and humidity swings inside a commercial grow environment.

One LMA-14G controls one group of lights. For facilities with multiple zones, deploy one adapter per zone and address each through the LCD. This modular architecture scales cleanly as a facility adds canopy or restructures room layout.

How It Fits a Commercial Build

In a typical commercial deployment, the LMA-14G installs between the TrolMaster Hydro-X Pro or Hydro-X Plus controller (via RJ12 cable) and the 0-10V dimming leads on your fixture drivers. The controller treats each LMA-14G as a separately addressable lighting group, which maps cleanly to a room, a bench run, or a cultivation stage. If the controller's native lighting ports are already occupied, TrolMaster's SPH-1 Splitter Hub can expand available RJ12 connections to accommodate additional adapters.

For facilities standardizing on TrolMaster automation — environmental monitoring, fertigation, CO2, and lighting all on one platform — the LMA-14G is the component that ensures your lighting zones aren't forced onto a one-size-fits-all schedule. Properly spec'd, it eliminates the need for separate standalone timers or secondary dimmer controllers for each zone, reducing both hardware count and the number of failure points in your lighting control chain.
