Group Control Lighting Adaptor, for ThinkGrow Model-I

Split ThinkGrow Model-I Fixtures Into Independent Groups

A single lighting schedule doesn't always fit an entire canopy, particularly when different sections of a room need their own dimming level or timing. The TrolMaster LMA-G Group Control Adapter is built for ThinkGrow single-bar LED fixtures, including Model-I and Model-I Plus, adding the ability to manage those lights in separate groups instead of one uniform block.

Connected inline with an LMA-T lighting control adapter, the LMA-G activates group control, letting growers create up to 10 lighting groups, each with its own independent settings.

Key Features & Benefits

• Built for ThinkGrow Single-Bar Fixtures — is designed specifically for Model-I and Model-I Plus lights.
• Up to 10 Lighting Groups — supports independent settings for each configured group.
• LCD Display — shows group addressing at a glance.
• Requires Inline LMA-T Connection — activates group control only when paired with an LMA-T adapter.

Who Should Use the LMA-G

Growers running multiple ThinkGrow single-bar fixtures who want to control sections of a canopy independently, rather than running the entire room on one schedule, are the intended users of the LMA-G. Each group requires its own LMA-G, so total group count should be planned before ordering.

About TrolMaster

The LMA-G extends TrolMaster's ThinkGrow lighting integration beyond simple on/off control, engineered at the Sacramento, California company's headquarters for growers who need section-by-section flexibility rather than a single uniform schedule. It works alongside the LMA-T rather than replacing it.

Frequently Asked Questions

Does the LMA-G work alone?

No, it must be connected inline with an LMA-T lighting control adapter to activate group control. Without that connection, group settings will not take effect.

How many groups can I create?

Up to 10 lighting groups, each with independent settings. Every group needs its own LMA-G adapter.

What fixtures is this compatible with?

ThinkGrow single-bar LED fixtures, including Model-I and Model-I Plus. It is not designed for ThinkGrow's LED strip products.

What's included in the box?

One Group Control Adapter and one 12-foot RJ12 to 4-pin connector cable (ECS-9). No additional cabling is required for a standard group setup.
