Notes on Dimming Compatibility
- #1: Transformers and dimmers are tested with the number of LED light sources specified. Using a different number may result in suboptimal behavior. Some combinations may support more light sources than tested.
- #1a: Non-LED dedicated dimmers/transformers can typically be loaded up to 20% of their maximum power for LED sources.
- #1b: LED-dedicated dimmers/transformers can be loaded up to their specified maximum power.
- #2: Check LED light source packaging for compatibility with occupancy motion sensors.
- #3: Dimming range color indications: Green (min <30%, max ≥80%), Yellow (min 30%-50%, max ≥70%), Red (not compatible), Grey (not applicable), White (no data).
- #3a: Single point flicker within the dimming range is acceptable.
- #4: Some dimmer suppliers offer "active loads" (e.g., Busch Jaeger Compensator 6596) to improve dimming performance.
- #5: Performance may vary with different mains voltages as tests were conducted under nominal conditions.
- #6: Manufacturers may update dimmer/transformer designs, potentially affecting LED compatibility.
- #7: Philips/Signify dimmable LEDs are generally compatible with all dimmer types (R, RL, RC, RLC).
- #8: Mixing loads may lead to unexpected behavior or damage; Philips is not responsible for such issues.
- #9: LEDs are dimmable within the indicated range but may exhibit minor flickering at certain settings.
- #10: Information is believed accurate but provided "AS IS".
- #11: DALI ET test data is based on Dynalite DDBC120-DALI controller under limited conditions. Signify reserves the right to final interpretation.
