GFX-DIM Universal Dimmer
Product Information:
The Universal Dimmer is a device designed for controlling
horticultural lights. It allows users to adjust the dimming level
of the lights. The dimmer is compatible with various lighting
manufacturers and can be operated with or without an internet
connection. The package includes the Universal Dimmer, a screw
terminal adapter cable, a power adapter, and a quickstart
guide.
Safety Precautions:
- Always consult lighting manufacturer’s product documentation
before installing, servicing, or operating horticultural
lights. - Respect all locally applicable laws, codes, and
regulations. - Avoid staring at operating lights as they may emit hazardous
optical radiation, including invisible UV and IR light. Use proper
vision protection and light blocking protective clothing when
working near or below operating lights. - Take precautions to avoid electrical shock when servicing or
installing horticultural lights. Follow the safety precautions
provided by your lighting manufacturer and ensure AC power service
to lights is connected to (earth) ground.

Product Usage Instructions:
Step 1: Plug in Dimmer
Only use the AC power adapter included with your Dimmer. If
waterproof power connection is required, use an IP67 power cable
available separately from GrowFlux.
Step 2: Connect Dimmer to Light(s)
Before servicing wiring, disconnect AC power from your lights.
Consult your lighting manufacturer’s documentation to verify proper
signal connections.
Connect the Dimmer to your light(s) using the supplied adapter
cable or dimming signal cabling (sold separately). Follow the
wiring diagram provided on the next page for the included
cable.
Unscrew the cable gland from the adapter cable, insert the
dimming signal cable through the seal, and connect the wires to the
internal terminals. Use a Philips screwdriver to secure the wires
in the screw terminals on the included cable. The cable gland seal
accepts wires with a diameter of 4mm to 6.5mm.
For most lights, connect the Violet wire to the copper terminal
(DIM +) and connect the Black/Gray/White wire to the silver
terminal (DIM -). Refer to your lighting manufacturer’s
documentation for specific instructions.

FAQ
IS THE UNIVERSAL DIMMER COMPATIBLE WITH MY GROW LIGHT? The Universal dimmer is compatible with any light that accepts analog 0 10V dimming. Most horticultural lights support dim-to-off; this feature is supported by the Universal Dimmer. Pick from a library of compatible lights in the GrowFlux dashboard to estimate the output in horticultural units (micromoles), including photosynthetic photon flux density (PPFD), daily light integral (DLI), and power consumption. If your light is not already in the light library, input the light’s wattage and PPFD measurements to create a custom light model.
11
FAQ
HOW CAN I GET ACCURATE PPFD CALCULATIONS IN THE INTERFACE? PPFD measurements taken at the canopy level can be entered into the interface to calculate PPFD within Light Formulas. See the PAR Calculation Guide at growflux.com/dimmer for more information or ask your lighting designer for these values. IS THE DIMMER WATERPROOF? When powered with the included AC adapter with a 2.5mm x 5.5mm barrel jack connector, the Universal Dimmer is NOT waterproof. When connected with an IP67 power cable (available from GrowFlux), the Universal Dimmer is fully waterproof. Contact GrowFlux or your authorized distributor for a waterproof power cable.
12
FAQ
DOES THE DIMMER WORK WITHOUT AN INTERNET CONNECTION?
Yes – the Universal Dimmer can be operated without an Access Point with push-button control.
WHAT ABOUT THE BUTTONS?
If the Universal Dimmer is not connected to a GrowFlux Mesh network, dimming level can be adjusted with push-button control. The set light level will stay fixed indefinitely, even through power cycling the Universal Dimmer.
If the Universal Dimmer is connected to a GrowFlux Mesh network, the buttons are disabled. Buttons are enabled if the Universal Dimmer loses Mesh connectivity.
