I bought one of these beauties from Room & Board (also available from Design Within Reach) in the bronze finish.
It’s a task lamp with 18 white LEDs. Light intensity can be controlled via a rotary knob, although the lowest level is still fairly bright. The Brazo can be adjusted in 4 degrees of freedom for maximal control. The base and arm are aluminum (available in bronze, natural silver, white and black) with a machined concentric reticular pattern that looks impressive, although I am concerned it will also be a very effective dust trap. Best of all, it’s designed locally in San Francisco by a Venezuelan-born designer.
