Lantern Schedule Lighting Adapter Compatible with any light controlled by 0~10V code

What the LMA-24 Does

The TrolMaster LMA-24 Lantern Schedule Lighting Adapter is purpose-built to automate the lantern photoperiod — a well-documented vegetative lighting strategy in commercial horticulture. The schedule runs as follows: 12 hours lights on, 5.5 hours off, 1 hour on, 5.5 hours off, then repeat. The 1-hour interruption during the dark period signals the plant to remain in vegetative state, preventing premature transition to flowering under long-day-sensitive genetics.

To execute this split schedule, the LMA-24 uses both lighting control channels on the TrolMaster Hydro-X (HCS-1, HCS-2, or HCS-3) simultaneously — one channel drives the primary 12-hour photoperiod, the other handles the 1-hour night interruption. The result is a fully automated, controller-managed lantern cycle with no additional timers or manual intervention required.

Fixture Compatibility

The LMA-24 is designed for any lighting system that accepts a standard 0–10V low-voltage control signal. This covers a broad range of commercial-grade HID fixtures — including Gavita, Nanolux, Luxx, Growers Choice, Illuminar, and PL ballasts — as well as LED systems such as Fluence, Next Light, and Spectrum King, among others. If your fixture has a 0–10V dimming or control input, the LMA-24 can drive it.

TrolMaster produces an entire family of LMA adapters, each targeting a specific fixture protocol (Phantom, Dimlux, SunSystem, etc.). The LMA-24 is specifically for the universal 0–10V standard, making it the most broadly applicable adapter in the lineup for facilities running modern commercial drivers or ballasts. Confirm your fixture's control input type before ordering — if it uses a proprietary protocol, a different LMA model may be required.

Where It Fits in a Commercial Build

For vegetative rooms running long-day or indefinite-vegetative schedules, the lantern photoperiod is a scientifically supported alternative to a straight 18/6 schedule, and the LMA-24 is the hardware that makes it controller-managed rather than manually timed. It is particularly relevant in multi-room facilities where the veg room's photoperiod needs to be logged, repeatable, and remotely adjustable alongside temperature, humidity, CO2, and irrigation — all within the same Hydro-X environment.

The LMA-24 connects directly to the Hydro-X lighting control ports and integrates cleanly into an existing TrolMaster wiring scheme. Where multiple adapters are needed across a large canopy, TrolMaster's SPH-1 Splitter Hub can expand the system's capacity by boosting signals and providing additional RJ12 output ports, keeping the installation organized and eliminating daisy-chain Y-splitters.

Installation & System Integration

The LMA-24 uses TrolMaster's standard RJ12 connection interface, consistent with the rest of the Hydro-X accessory ecosystem. It occupies both lighting control channels on the controller — Channel 1 and Channel 2 — to coordinate the two separate on-periods that make up the lantern cycle. Because both channels are consumed by the LMA-24, plan accordingly if you need independent control of multiple fixture zones; in those cases, additional Hydro-X controllers or a group control adapter may be the right configuration.

The adapter is rated for a working environment of 0–50°C and up to 90% relative humidity, appropriate for standard controlled-environment grow rooms. Package dimensions are 160mm × 86mm × 86mm and the gross packaged weight is approximately 60g, making it compact and easy to mount or tuck into an existing control panel. Refer to the TrolMaster LMA-24 tech sheet (available in the Trolmaster Help Center) for full wiring diagrams before installation.
