How to configure or set the lighting on a Razer device with Razer Synapse 3

| Answer ID: 1895
This is a guide on how to configure or set the lighting on a Razer device with Razer Synapse 3.

Effective February 3, 2026, Razer Synapse 3 will no longer receive updates or support cloud services. After this date, cloud syncing of configurations across PCs using the same Razer ID will be disabled.

Note: Your installed devices will continue to be configurable in Razer Synapse 3. However, if you uninstall these devices completely, you will need to upgrade to Razer Synapse 4 to continue customization.

Download Razer Synapse 4 and migrate your existing Razer Synapse 3 profiles using the Profile Migration Tool to retain access to your configurations. See How to migrate your Razer Synapse 3 Profile to Razer Synapse 4 for instructions.

Note: Lighting settings and Chroma effects differ. Chroma effects focus on the lighting effect and color applications on your device, while the lighting settings focus on brightness and trigger to switch off the lighting.

  1. Open Razer Synapse 3.

  2. Select your Razer device from the list of devices. In this example, we are going to enable the lighting on a Razer mat.

  3. Select the lighting setting to change:

    • Brightness – located at the upper-left side of the Razer Synapse window.
    • Switch off lighting – located at the lower-right side.
