Flush mount ceiling light or pendant: how to decide
A flush mount ceiling light is the obvious choice under 8 ft 2 in (2.5 m), in rooms people walk through and anywhere a pendant would be in the line of sight: entryway, hallway, low bedroom, open kitchen. It lights more evenly, because the light starts at the ceiling and bounces off it. A pendant remains preferable above a table or an island, where you want to bring the light closer to the surface. In a combined living and dining room, the two pair well: a ceiling light in the center of the living area, a pendant above the table.
