Lighting Adapter Converted to Digital Signals for TG LEDs

Precision Digital Dimming for ThinkGrow LED Strips

ThinkGrow LED light strips need a stable, precisely controlled brightness signal rather than a simple on/off switch, and covering longer transmission distances without signal degradation adds another requirement on top of that. The TrolMaster LMA-9 is a precision dimming adapter built for exactly that job, interfacing with Hydro-X controllers through the LMA-14 module and adjusting connected ThinkGrow LED light strips' brightness based on the voltage signal it receives.

It communicates with the light strips over RS485, a protocol suited to long transmission distances and a stable signal across the varied environmental conditions found in both indoor grow rooms and greenhouses.

Key Features & Benefits

• Precision Brightness Control — adjusts connected ThinkGrow LED strips based on the received voltage signal.
• RS485 Communication — maintains a stable signal over long transmission distances.
• Works Through the LMA-14 Module — interfaces with Hydro-X controllers via the LMA-14 rather than connecting directly.
• LED Activity Indicator — shows adapter status at a glance.

Who Should Use the LMA-9

Growers running ThinkGrow LED light strips, particularly in greenhouses or larger rooms where the dimming signal has to travel a longer distance, are the intended users of the LMA-9. It's built specifically for strip-style ThinkGrow fixtures rather than the company's single-bar Model-I lineup.

About TrolMaster

The LMA-9 is one of several adapters tying TrolMaster's Sacramento, California-engineered Hydro-X controllers into ThinkGrow's LED product line, reflecting the operational relationship between the two affiliated brands. Its RS485 backbone is a deliberate choice for reliability in larger installations where a simpler signal type might degrade over distance.

Frequently Asked Questions

What does the LMA-9 connect to?

It interfaces with Hydro-X controllers through the LMA-14 module rather than plugging directly into the controller. The LMA-14 must already be installed for the LMA-9 to function.

What communication protocol does it use with the light strips?

RS485, chosen for long transmission distances and a stable signal. This suits both indoor rooms and larger greenhouse installations.

What's included in the box?

One LMA-9 adapter, one 12-foot RJ12 to 4-pin IP65 connector cable (ECS-9), and one power and signal connection cable set. No additional cables need to be sourced separately.

How is the LMA-9 different from the LMA-14 it connects through?

The LMA-14 handles general 0-10V protocol lighting control, while the LMA-9 adds precision digital dimming specifically for ThinkGrow LED strips. The two work together rather than as alternatives to each other.
