It covers common issues such as flickering, buzzing, or unresponsiveness and offers practical solutions for a stable and reliable setup. **Signs of incompatibility can affect the performance of your lighting and other connected devices, leading to issues such as flickering, buzzing, or unresponsiveness. Identifying these signs early helps ensure seamless operation and prevents potential disruptions. This article outlines common compatibility issues, their causes, and the steps you can take to resolve them effectively.** ### πŸ” Understanding Bulb Incompatibility If your lights are flickering or not responding as expected, they may not be fully compatible with your Lightwave system. Bulb incompatibility is a common issue that can affect performance, particularly with dimmable bulbs. Identifying and resolving these issues ensures a smooth and reliable lighting experience. ### ⚠️ Signs on the Dimmer - **πŸ”„ Flashing Green and Purple – Calibration Loop** – Try switching it off from the consumer unit for a few seconds and turning it back on. However, this indicates that the dimmer is not compatible with the bulbs you are using. - Ensure the bulbs are not **12V LED Strip or Bulbs, non-dimmable, and meet the minimum wattage requirements.** For more information on minimum wattage requirements, check our compatibility guide [here](https://support.lightwaverf.com/knowledge/why-are-my-lights-slightly-dim?hsLang=en). - **🚨 Flashing Red** – A strong indication that the dimmer does not support the current load. - Ensure the bulbs are not **12V LED Strip or Bulbs, non-dimmable, and meet the minimum wattage requirements.** For more information on minimum wattage requirements, check our compatibility guide [here](https://support.lightwaverf.com/knowledge/why-are-my-lights-slightly-dim?hsLang=en). ### πŸ’‘ Signs on the Bulbs - **✨ Flickering when dimming** – Often indicates an incompatibility between the bulb and the dimmer. - **⚑ Flickering when off** – Some bulbs may briefly flicker due to residual voltage. - **πŸ”† Permanently on (Residual Glow)** – This can occur with certain LED bulbs. For additional details on residual glow and how to address it, check our detailed guide [here](https://support.lightwaverf.com/knowledge/why-are-my-lights-slightly-dim?hsLang=en). - **🌟 Flickering at full brightness** – The bulb may require calibration to function correctly. For a step-by-step calibration process, refer to our calibration guide [here](https://support.lightwaverf.com/knowledge/how-to-calibrate-your-dimmer-for-optimal-performance?hsLang=en). ### βœ… Ensuring a Compatible Setup For the best performance, always check Lightwave’s list of tested bulbs before purchasing.
