Lighting Science, Health & Productivity

Match desk lamp Kelvin to tasks and time of day to cut eye strain, improve focus, and protect sleep. Get clear ranges and an easy preset framework to tune light for reading, screens, color work, and late nights.

Reduce eye strain and errors with a layered setup that hits a precise 3:1 task-to-ambient ratio, verifies lux at the work surface, controls glare, minimizes flicker, and tunes color temperature through the day. Use the 10-minute phone-based audit to calibrate your desk lighting and track measurable comfort gains.

Prioritize usable, even, flicker-stable light at the desk - not big lumen numbers - to reduce eye strain and sustain deep focus. Learn clear metrics and simple at-desk tests (around 500 lux with uniformity ≥0.6, PstLM <1.0 across dimming, and precise beam control), plus day/night color guidance to boost productivity without harming sleep.

Reduce eye strain by optimizing for metrics, not lumens: target 500 lux at desk height with uniform, flicker-stable lighting and glare-free placement. Follow simple measurement steps and a quick checklist to verify your setup.
