For comfortable reading choose a lamp delivering 800 to 1,100 lumens, roughly the output of a 60 to 75 watt incandescent bulb. For ambient or accent light on a console or sideboard, 400 to 800 lumens is plenty. Warm white at 2700K to 3000K suits living rooms and bedrooms, while 3500K to 4000K keeps text and detail crisp at a desk. A dimmable lamp covers both uses from a single fixture, which is why most of this collection ships dimmable.
