The TrolMaster LMA-9 is a dual-channel lighting adapter that converts standard 0–10V analog dimming signals into the digital RS485 protocol used by ThinkGrow LED fixtures. This allows ThinkGrow lights to be controlled from TrolMaster Hydro-X or other third-party environmental controllers that provide standard 0–10V outputs. Its two independent channels preserve separate control of the fixture's full-spectrum and supplemental-red diode arrays, rather than combining them into one dimming signal.
• SKU: LMA-9

• Operating Humidity: 5–90% RH
• Status Indicator: Built-in LED for signal/connection verification
• Fixture Connection: RJ12 to the first ThinkGrow fixture in the lighting string
• Daisy-Chain: ThinkGrow fixtures can be chained from the first fixture; maximum count depends on the specific fixture model

• In the Box: LMA-9 adapter, ECS-9 12-ft RJ12-to-4-pin IP65 cable, power and signal connection cables
Key Advantage: The LMA-9 preserves independent full-spectrum and supplemental-red control when integrating ThinkGrow LEDs into a conventional 0–10V lighting-control system. This lets operators retain the fixture's dual-channel spectrum capability while keeping lighting schedules and dimming under an existing Hydro-X or other 0–10V control platform.
