TrolMaster 4-Pin Waterproof Splitter Cable

Interconnect Multiple ThinkGrow Fixtures or LMA-T Modules

Wiring several ThinkGrow LED fixtures or LMA-T modules together on one lighting line calls for a splitter that can handle the moisture and dust common in a grow environment, not just a bare RJ12 branch. The TrolMaster ECS-12 is a 4-pin IP65 cable built for exactly that job, interconnecting multiple ThinkGrow LEDs or LMA-T modules within the ThinkGrow lighting system.

Its waterproof, dustproof construction holds up where moisture and dust are routine, and because it uses the same connector as the primary fixture cabling, it also works as a replacement or spare part when a cable in the field needs swapping.

Key Features & Benefits

• 4-Pin IP65 Rated — seals against both water intrusion and dust.
• Connects Adapter to Fixture — bridges the TrolMaster lighting adapter with a ThinkGrow LED.
• Connects Multiple Fixtures to SPH-1 — supports wiring more than one fixture on a shared line.
• Doubles as a Spare Part — serves as a drop-in replacement cable when one fails.

Who Should Use the ECS-12 Splitter Cable

ThinkGrow lighting system users who need to interconnect multiple LED fixtures or LMA-T modules, including in moist or dusty grow environments, are the intended buyer for the ECS-12. Keeping a spare on hand is also common practice for facilities running several fixtures on one line.

About TrolMaster

The ECS-12 is one of the cables that ties TrolMaster's Sacramento, California-engineered Hydro-X controllers into ThinkGrow's LED lighting system, reflecting the working relationship between the two affiliated brands. Splitter cables like this one are what let a single lighting adapter manage more than one fixture at a time.

Frequently Asked Questions

What's the IP rating?

IP65, sealed against both water and dust intrusion. That suits typical grow-room and greenhouse conditions.

What does it connect?

Multiple ThinkGrow LEDs or LMA-T modules within the ThinkGrow lighting system. It is not compatible with fixtures outside that system.

What's the working temperature range?

32-122°F (0-50°C). Working humidity is rated at 90% or less.

Can it be used as a spare part?

Yes, it can also serve as a replacement for a failed fixture or splitter cable. Keeping one on hand avoids downtime if a cable fails in the field.

How many fixtures can be daisy-chained on one ECS-12 run?

The practical limit depends on the SPH-1 or LMA-T module's own output rating rather than the cable itself. Checking that module's specification sheet confirms the maximum fixture count for a given line.
