An upgrade from the standard desk lamp, the Kilby Court walnut LED Wireless Charging Mult-Function Desk Lamp takes desk lamps to the next level with extra functionality and a sleek black and walnut wood finish. Full control over the 5 different color temperature modes and 5 different brightness levels offers an infinite range of lighting selections. In addition, a Qi certified wireless charging pad is conveniently located inside of the base. Many smartphones (list below) have Qi technology built in, so just place your phone on the pad and it will charge right up. No cords, no mess. It's that easy! A USB is located on the base and can charge up a second device simultaneously. The LED's are integrated into this lamp and are not replaceable. However, our LED's are top quality and last around 50,000 hours! Partial assembly may be required.
