The TrolMaster LMA-15 is a specialised lighting control adapter designed to connect compatible DLI-controlled lighting fixtures to the TrolMaster Hydro-X environmental control system, enabling centralised switching and dimming through the controller.

Rather than switching the mains supply to the lighting fixtures, the LMA-15 communicates with compatible lighting equipment through its low-voltage DLI control interface. This allows the Hydro-X to manage lighting output while the fixtures remain connected to their normal electrical supply.

Once integrated into a compatible installation, the Hydro-X can control the connected lighting system according to programmed lighting schedules and output settings, bringing lighting management into the same platform used for environmental control.

The LMA-15 is intended specifically for lighting systems using the compatible DLI control protocol. Lighting-control protocols and connections vary considerably between manufacturers, so fixture compatibility should always be confirmed before installation.

Why choose the TrolMaster LMA-15?

  • Hydro-X lighting integration - connects compatible DLI lighting systems to the TrolMaster Hydro-X controller.
  • Centralised lighting control - manage compatible lighting alongside temperature, humidity and other environmental functions.
  • Lighting output adjustment - enables compatible fixtures to respond to dimming commands from the TrolMaster controller.
  • Automated lighting schedules - integrate lighting operation with programmed day and night periods.
  • Low-voltage control interface - communicates with the fixture's control system rather than carrying the main lighting load.
  • Purpose-built DLI adapter - designed specifically for compatible fixtures using the DLI lighting-control protocol.
  • Plug-and-play TrolMaster design - provides a straightforward interface between compatible lighting equipment and the Hydro-X control network.
  • Suitable for multi-fixture installations - compatible fixtures can be linked according to the lighting manufacturer's control-network requirements.

Bring lighting into the Hydro-X control system

Environmental control and lighting are closely connected. Lighting affects crop development as well as the heat load placed on the controlled environment, so incorporating lighting into the same control platform can simplify day-to-day management.

The LMA-15 acts as the communication interface between the Hydro-X and a compatible DLI lighting system. The Hydro-X provides the control commands, while the LMA-15 translates those commands into the signal required by the compatible lighting fixtures.

This allows the lighting system to form part of the wider TrolMaster environmental-control installation without requiring the controller itself to carry the electrical load of the fixtures.

Automated dimming control

When used with compatible dimmable fixtures, the LMA-15 allows lighting output to be adjusted through the TrolMaster controller rather than relying solely on manual controls fitted to individual luminaires.

This is particularly useful in installations containing multiple fixtures, where manually adjusting every luminaire can be time-consuming and can make consistent settings more difficult to maintain.

Centralised dimming also provides greater flexibility when different light-output levels are required as a crop develops.

DLI protocol vs Daily Light Integral

In the LMA-15 product name, DLI refers to the lighting control interface used by compatible fixtures. It should not be confused with Daily Light Integral, which is a horticultural measurement describing the total quantity of photosynthetically active light received over a 24-hour period.

The LMA-15 does not itself measure PAR, PPFD or Daily Light Integral. Where actual photosynthetic light measurement is required, TrolMaster's MBS-PAR Full Spectrum Quantum Sensor is designed for that purpose on compatible control systems.

Check lighting compatibility before installation

Lighting manufacturers use several different control protocols and connector arrangements. The LMA-15 should therefore only be used with fixtures specifically compatible with its DLI control interface.

Do not select a lighting adapter purely on the basis that a fixture is dimmable. A fixture may use 0-10V, PWM, RS485, DLI or another manufacturer-specific control method, and the correct TrolMaster adapter must match the lighting system.

If the lighting system uses a different control protocol, another adapter from the TrolMaster LMA range may be required.

How the LMA-15 works

The LMA-15 is installed between the compatible TrolMaster control network and the lighting system's low-voltage control connection.

The lighting fixtures continue to receive their normal mains electrical supply independently. The LMA-15 carries control information only and does not act as a mains contactor or provide operating power to the fixtures.

Where several compatible fixtures are linked together, follow the lighting manufacturer's requirements for control cabling, daisy-chaining and maximum fixture quantities.

TrolMaster LMA-15 Lighting Control Adapter FAQs

What does the TrolMaster LMA-15 do?

The LMA-15 provides an interface between a compatible TrolMaster Hydro-X controller and lighting fixtures using the supported DLI control protocol.

Can the LMA-15 dim compatible lights?

Yes. When used with compatible dimmable lighting equipment, the LMA-15 allows lighting output to be controlled through the TrolMaster system.

Can the Hydro-X automatically switch the lights on and off?

Yes. Compatible lighting can be operated according to lighting schedules configured through the TrolMaster control system.

Does DLI mean Daily Light Integral on the LMA-15?

No. In the context of the LMA-15, DLI identifies the compatible lighting control interface. The adapter does not itself measure Daily Light Integral.

Does the LMA-15 measure PAR or PPFD?

No. It is a lighting control adapter rather than a light sensor. PAR and PPFD measurement requires a compatible quantum sensor such as the TrolMaster MBS-PAR.

Will the LMA-15 work with any dimmable LED fixture?

No. Dimmable lighting systems can use different communication protocols. The fixture must be compatible with the control interface supported by the LMA-15.

Can I use the LMA-15 with a 0-10V light?

Not simply because the fixture is dimmable. TrolMaster produces different LMA adapters for different lighting protocols, so the correct adapter should be selected for the specific fixture.

Does the LMA-15 power the lighting fixtures?

No. The lighting fixtures retain their normal mains electrical supply. The LMA-15 handles the low-voltage control signal used to manage compatible fixtures.

Does the LMA-15 replace a lighting contactor?

No. It is a control-interface adapter and does not carry the mains electrical load of the connected lighting system.

Can multiple compatible lights be controlled together?

Yes, where the lighting system supports linking multiple fixtures through its control network. Always follow the fixture manufacturer's requirements for control cabling and maximum connected fixture quantities.

Why use centralised lighting control?

Centralised control allows compatible fixtures to follow common schedules and output settings without manually adjusting each individual luminaire, making larger installations easier to manage consistently.

Can lighting output be changed as the crop develops?

Yes. Compatible dimmable lighting can be operated at different output levels through the TrolMaster system, allowing lighting intensity to be adjusted as requirements change.

How do I know whether my light needs an LMA-15?

Check the lighting manufacturer's control protocol and TrolMaster's compatibility information for the specific fixture model. The correct LMA adapter is determined by the control interface used by the lighting system.
