Unlike other reading lamps, our lamp features a special ET horizontal head that illuminates a wider lateral area with more uniform light. It provides a wide field of homogeneous illumination without harsh edges. The ET head design creates just the right amount of light to enjoy reading without disturbing others. 3 colors, 3 dimmable brightness levels. This bedside reading lamp has 3 color temperatures: amber (1800K), soft (3400K), and natural (6000K). Amber provides warm, dim light for night reading; soft provides cool white light for recreational reading; and natural restores daylight for high concentration and greater efficiency. You can also adjust the brightness levels to your preference. All e-readers are rechargeable via USB-C, which is a design with older users in mind.
