The fixture primarily provides glare-free downward directed light. The angle of the shade can be adjusted to optimize light distribution. A slim opening in the top of the shade provides soft, ambient upward illumination. A mechanical system provides great freedom of movement, so the light can always be set in the ideal position in the workspace, living room etc. Built-in LED technology provides a high quality of light with stepless dimming from 100% to 15%. Optional timer capability automatically turns off the light after a chosen duration of 4 or 8 hours. Returns to the last dim level setting when switched on. A button at the top of the tube acts as switch and dimmer.
