Fluence Whisper 2.0 Dimmer

Centralize Dimming Control Across an Entire Fluence Fixture Zone

The Fluence Whisper 2.0 Dimmer is a compact controller that manages 0-100% light intensity across up to 50 compatible Fluence LED fixtures from a single control point. It supports both 0-10V and PWM dimming protocols over up to 200ft of signal wire, integrating cleanly into commercial grow room control architectures without requiring complex building automation.

Its compact 3.92 x 3.43 x 1.35in footprint mounts easily in panels, junction boxes, or wall enclosures, and it accepts either 120V AC or 12V DC power input, making it adaptable to a range of panel and control cabinet configurations.

Key Features & Benefits

• Controls Up to 50 Fixtures: A single unit manages up to 50 compatible Fluence LED fixtures, reducing the number of control points in large commercial arrays.
• 0-100% Full-Range Dimming: Smooth, continuous dimming from full intensity down to minimum output for stage-specific light recipes.
• 200ft Signal Wire Range: Covers large grow rooms and multi-bay facilities without additional signal amplifiers in most layouts.
• 0-10V and PWM Compatibility: Works with a wide range of building management systems and third-party environmental controllers.
• 120V AC / 12V DC Power Input: Flexible power options adapt to diverse panel and control cabinet configurations.

Who Should Use This

Commercial indoor cultivators and facility managers running Fluence LED fixture arrays who want centralized, precise dimming control without complex building automation systems are the direct fit for the Whisper 2.0, particularly operations dialing in stage-specific light intensities or managing heat loads during peak temperatures.

Frequently Asked Questions

Can the Whisper 2.0 integrate with a building management system?

Yes, the Whisper 2.0's 0-10V output is compatible with most commercial building management systems and third-party environmental controllers that provide a 0-10V control signal. This enables automated dimming based on temperature, CO2 levels, or time-of-day schedules.

What happens if my array exceeds 50 fixtures?

For arrays exceeding 50 fixtures, deploy additional Whisper 2.0 units, one per zone of up to 50 fixtures. Each unit operates independently, so large facilities simply use one Whisper 2.0 per lighting zone or circuit.

How do I choose the right signal wire type and gauge for this dimmer?

Fluence recommends low-capacitance 2-conductor signal wire of the gauge specified in the Whisper 2.0 installation guide. Using the correct wire type and gauge ensures signal integrity over the full 200ft range and prevents dimming instability at long cable runs.

Can the Whisper 2.0 dim fixtures all the way to zero?

The Whisper 2.0 supports a 0-100% dimming range, but individual Fluence fixtures may have a minimum dimming floor below which they turn off rather than continuing to dim. Refer to your specific fixture's dimming specification for its effective minimum output level.
