Measuring and Understanding Light at Home
Walk your rooms at 9 a.m., noon, and 3 p.m. Note where direct beams land, measure lux at display spots, and track seasonal changes. Map reflections from mirrors and bright floors. This quick audit reveals sneaky angles and helps you move treasures before damage silently accumulates.
Measuring and Understanding Light at Home
Aim for around 50 lux for very sensitive items like textiles and watercolors, and under 200 lux for moderately sensitive objects. Keep UV minimal, ideally under 75 microwatts per lumen. Remember exposure is dose-driven: lux-hours add up over days and seasons, so brief midday beams really matter.
