The TrolMaster LMA-G is a group-control adapter designed specifically for ThinkGrow Model-I and Model-I Plus single-bar LED fixtures. Used inline with the LMA-T, it allows a single Hydro-X controller to divide ThinkGrow fixtures into independently addressable lighting zones, with each group able to have its own schedule and dimming settings. Up to 10 separate light groups can be addressed per controller channel.

Key Advantage: The LMA-G adds zone-level control to ThinkGrow Model-I lighting installations, allowing multiple production areas to operate independently from a single Hydro-X controller. The LMA-T provides the ThinkGrow protocol bridge, while each LMA-G assigns a separate group address for independent scheduling and dimming.
