The LED decorative table lamp is used mainly in places such as the bedroom, sitting room and so on for decorative illumination. It adopts LED white light technology, energy-conservation drive technology and single chip computer control technology, which makes it successful to take the place of traditional decorative table lamp that uses bulbs as its lighting source. We use rich and colorful LEDs in the decorative table lamp, which makes it more beautiful and full of artistic effect.

Three kinds of color change (seven-color gradual change, seven-color quick change, seven-color gradual change plus seven-color quick change) let users have more options.
