End table lamps can illuminate a living area on a table, and, you’ll want at least 450 lumens if you want to be able to read or write by the light of your end table lamp.

If the table is too tall, it will loom over the sofa. If it's too short, it will be dwarfed by the sofa. Picking a lamp for your end table is like picking art: It has to speak to you.
