About the product
- Ring-shaped Tunable White LED module with an adjustable colour temperature from 2700K to 6500K (= one print for 2700K or 6500K).
- This module can also be operated as a standard 2700K or 6500K version, as both colour temperatures can be controlled individually.
- Extremely high module efficiency (constant current)
- Very high colour rendering Ra >90 and still very high efficiency thanks to the new Samsung LM281B+PRO S90 LED
- Very narrow colour tolerance (MacAdam 3)
- The SIMRING is ideally suited for retrofitting an existing Circline luminaire or for circular downlights, wall luminaires and ceiling luminaires.
