Lighting Science, Health & Productivity

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.

Understand TM-30 and R9 to choose lamps that render colors faithfully, cut rework, and predict saturation shifts with Rf, Rg, and the TM-30 vector graphic.

Learn to assess blue-light risks in desk lamps with IEC 62471: read risk groups, match to your distance, and check flicker for lasting comfort.

Learn how to choose a desk lamp by color accuracy, not brightness: use CRI, R9, SPD, and TM-30 to judge spectrum quality and get true-to-life colors.
