While working at a building, a Duplicant can get a +15% speed bonus if they occupy a cell with at least 1 lux of light. This "Lit Workspace" status effect can be viewed when selecting a Duplicant, and generally applies to almost any operation that has a progress bar, which includes eating at a Mess Table, using a Lavatory, and pouring a drink from the Espresso Machine.
