There's no section in the home where LED lighting has taken off more than in the home office, where a myriad of task lights now flaunt their efficient LED credentials. But the Kelvin LED GREEN II has an extra trick up its sleeve: daylight and motion detection...
Designed by Antonio Citterio with Toan Nguyen, the Kelvin LED GREEN II (with Motion Sensor) Daylight/Motion Sensor is an update to a 2010 design. Offering no visible switches or buttons, the light is instead engaged by touch at the top of the lamp head where users can choose between 100%-66%-33% brightness emanating from 30 2700K temperature LED bulbs (the same warm temperature as incandescent lights), with a highly positionable double pantograph arm and nearly 360 degree head that would make any architect happy.
Where the updated Kelvin LED Green Mode I & II improves on the original is with an eco-energy setting; once the Daylight Sensor is activated by touch (indicated by a color change from orange to green at the top of the lamp), similar to the auto screen brightness featured in most smartphones, the lamp's output is then automatically regulated according to the brightness of the work surface it is illuminating.
Additionally, a motion-detecting sensor keeps tabs on movement around the lamp, putting the light into sleep mode after 5 minutes if no movement is detected, and completely off after 2 hours of stillness. It's all icing on a cake when the task light only requires 8.4 watts for operation, but ideal for anyone who works from a desk long into the night and doesn't want to worry about leaving the light on.
