Who This Is For

  • You are integrating 3.5mm pigtail LEDs into a TrolMaster setup because standard RJ12 cables do not fit the ports.
  • You are expanding your control network because your specific light fixtures require a 3.5mm pigtail connection point.

What We Found

  • The T-shaped splitter is the real hero here since it lets you chain multiple pigtail fixtures from a single port.
  • We found the 16-foot cable length is usually plenty to reach from the controller to the first light in a 4x8 tent.

What Users Say

  • Users who added this kit say they finally got their mismatched LED brands talking to the same central controller.
  • Buyers report that the included barrel connector made it possible to fix short pigtail leads without any soldering.

TrolMaster ECS-2 RJ12 to 3.5mm Pigtail LED Cable Kit

LED grow lights that use pigtail (3.5mm) wiring require a different cable interface than standard RJ12 connections — and the TrolMaster ECS-2 provides exactly that. This cable kit bridges a controller like the TrolMaster Hydro-X HCS-2 to pigtail-wired LED fixtures, including a 16ft RJ12 cable for controller-side reach, a 4ft RJ12 to 3.5mm jack adapter for the fixture-side connection, a T-shaped splitter for branching, and a 3.5mm female barrel connector. Everything needed for a clean pigtail LED integration is in the box — plug in and go.

FAQs

What is the ECS-2 used for? +

The ECS-2 is a cable kit that connects a TrolMaster controller to LED grow lights that use pigtail (3.5mm) wiring — a common interface on many LED fixtures that cannot connect via a standard RJ12 cable alone. The kit includes all the cables and connectors needed for a complete installation without sourcing additional parts.

What is the difference between the ECS-1 and the ECS-2? +

The TrolMaster ECS-1 is a standard RJ12 cable and splitter kit for extending module and sensor connections within the TrolMaster ecosystem — it uses male-to-male RJ12 cables throughout. The ECS-2 is specifically designed for LED grow lights with pigtail (3.5mm) wiring, and includes a 4ft RJ12-to-3.5mm adapter cable and a female barrel connector. For other specialized lighting interfaces, you may also consider the ECS-3 or ECS-5 kits.

Which LED fixtures is the ECS-2 compatible with? +

The ECS-2 is designed for LED grow lights that use a 3.5mm pigtail dimming interface — one of the most common LED control input formats. If your fixture has a 3.5mm pigtail or barrel dimming port, the ECS-2 should provide the correct connection. If you are unsure about your fixture's dimming input type, consult the fixture's documentation or contact TrolMaster support before ordering.

What does the 3.5mm female barrel connector do? +

The 3.5mm female barrel connector provides the termination point for the fixture-side connection, allowing the ECS-2 to mate with the LED fixture's pigtail dimming port. It works in conjunction with the 4ft RJ12-to-3.5mm adapter cable to complete the signal path between the TrolMaster controller and the LED fixture.

Can I use the ECS-2 alongside an LMA adapter? +

The ECS-2 provides the physical cable connection between the controller and pigtail LED fixtures. Depending on your specific fixture and control setup, an LMA series adapter, such as the TrolMaster Hydro-X LMA-9, may also be required to handle signal conversion between the controller's output and the fixture's control input. Consult your fixture's documentation to determine whether both components are needed for your specific integration.
