Do you want the best dimming? Do you want to use your light's full potential? Do you want to create scenes and record and call up your favorite lighting moods? And all without laying new cables and involving a specialist? Then the GRAU app is exactly the tool you need to achieve this. You can control lights with the GRAU app either via the app, or you can pair the lights with Bluetooth-enabled buttons, so you only need the app for setup and not for daily operation. This Bluetooth dimming is already integrated into the Team and Flying lights, and we can also install this control in other GRAU lights. Information about which lights offer the GRAU app control option can be found on the respective product pages in the e-shop area. If you have any further questions, please feel free to contact us.
