A beautifully unified piece of design made from aluminium and opal glass. The base is a faceted cylinder that works as both the light switch and the stem that holds the spherical glass diffuser in place. Turning the base in a clockwise direction clicks the LED light on, with further rotation increasing the lumen output. This movement built into the design, allows the user to intuitively brighten or dim the light. The base comes in four anodised finishes: black, aluminium, orange or green. Turn On is a design made at human scale, effortlessly simple and pleasing to touch.
