The exposure of an artifact to light is a product of illumination level and time: Light level (lux) x Time (hours) = Exposure (lux hours) Understanding this formula, it is clear that exhibiting an object for 1 hour at 100,000 lux (direct sunlight) is equivalent to exhibiting the object for 200 hours at 50 lux (museum lighting).

• Lighting levels (photopic illuminance) are assumed to be appropriate for the task in both the baseline condition and the post-installation condition. If baseline lighting levels are too low for the task, the lighting should be repaired, refreshed, or modified as needed for an appropriate comparison. 2.2 Site Selection and Setup
