Touch & Touch with a touch and a heat-detecting sensor. A touch sensor is installed on the front side of the product. By using the touch sensor when you are at the table, you can adjust the levels of brightness appropriate for different activities (such as drinking wine, drinking tea, having meals, and reading books), without leaving the table or getting off the chair in order to use the switch on the wall or use a remote control. Four different modes of color temperature are available: “2,500K” for “drinking wine”, “4,200K” for “drinking tea”, “5,200K” for meals and “6,400K” for “reading books”.
