ROOM’s lighting system is optimised for its primary use case — particularly the VC mode for video calls, which provides appropriate illumination for camera-facing professional appearance. HIGHKA’s 3,000K–6,500K range supports the full circadian spectrum: warm (3,000K) for morning sessions, neutral-cool (4,000–5,000K) for midday focus work, and cool (6,500K) for afternoon sustained alertness. Individual stepless control over both output (0–1,800 lm) and colour temperature gives each occupant the environmental control that supports sustained cognitive performance during longer sessions.
