Dimmable andd Tonable White Fixtures

Dimpable fixtures allow clicicisians to adjuss light levels to suit different activies - bright (500 + lux) for procedures and charting, moderate (200- 300 lux) for general observation, and very dim (10- 50 lux) for nightim monitoring to avoid difficient patients.

Dimmable and tunable systems rely on digital control such as DALI or Zigbee, which enable precise, individual fixture control.

Integration with nurse call systems or patent monitoring plats automate lighting changes based on alarms or patient status (e.g., raiving lights during a Coding a Blue).
