controlled exposure to ambient light moderate ambient light exposure 1,000 to 15,000 lux exposure 2026-01-08T17:01:15Z GEO:GSE306375 PMID:41484209 This is any condition in which the main influencing factor is exposure to controlled moderate ambient light at an intensity of about 1,000 to 15,000 lux, which is somewhere between normal home lighting (50-150 lux) and direct sunlight (100,000 lux). 1,000 lux means that 1000 lumens (a measure of total light output) are distributed over an area of 1 square meter (1000 lm/m²).
