The Lunatone DALI-2 Display 4" packs Lunatone's touchscreen lighting control into a compact 88 × 88 mm format that mounts on a standard back box — the size of a light switch, the capability of a control panel. Its capacitive 4-inch screen with 24-bit colour depth handles configuration, control and operation of a DALI system directly from the wall.Key features Dimming and switching of DALI groups and individual addresses Scene recall, RGB colour management and colour temperature control (DT8) Widget-based interface, customisable per room and per user DALI and WLAN interfaces Integrated sensors: temperature, humidity, air pressure, air quality Multimaster capable, DALI-2 certified Technical specifications Screen 4" capacitive touch, 24-bit colour Supply 24–56V DC (SELV), 3W — recommended PSU: PS 24V 130mA or 300mA Interfaces DALI, WLAN Mounting on back box (standard installation box) Dimensions 88 × 88 × 8.5 mm Ambient temperature 0°C to +45°C · IP20 Available with white or black frame. The 4-inch format is the right choice for individual rooms — offices, meeting rooms, hotel suites, residential living areas — where a full 7-inch panel would be oversized but the client still wants touch control of scenes and colour.
