Lighting Science, Health & Productivity

Understand IEC 62471 risk groups, how to read lamp safety labels, and how flicker, CCT, and illuminance choices reduce eye strain at the desk.

Avoid CRI-only traps. Use R9 and TM-30 to judge true color, test dimming and flicker, and set spec baselines that match casual, video, or color-critical work.

Learn to tune desk lighting for reading and video calls: measure real lux, set CRI/R9 and CCT, cut glare and flicker, and use presets for seamless mode shifts.

Learn how to choose and position task lighting for low vision: measure lux, prioritize high CRI/R9, and ensure even beams to reduce fatigue and see true color.

Position lamps by height and angle to deliver 200+ EML to your eyes, cut glare, and switch morning/evening setups to boost daytime alertness and sleep.
