Walnut wood and brushed steel pair off in a sharply angled task lamp that uses LEDs for top performance. The shade arm (which is detached for shipping) revolves 360? to direct light where it?s needed. The 9 Watt LED produces 450 lumens of warm light that turns on and off using a rocker switch located underneath the shade. This lamp has a black cord and is smart outlet compatible. The LED bulbs are integrated into the lamp and are not replaceable, but last 50,000 hours.
