A single small lamp leaves dark corners across two screens, and finding the best desk lamp for dual monitors starts with the width: the lamp should span both monitors and state its lumens, color modes and mount. We compared five desk lamps by stated width, brightness, color modes, mount and warranty. Every figure below comes from the listings; where a listing contradicts itself, we say so.
