▽Hidden Cable▼: New design, the USB cable is perfectly hidden! The cable can be cleverly hidden in the base of the lamp by slightly twisting the bulb, so you don't need to wind the cable manually. The distance between every 2 bulbs is adjustable (9-33cm). ▽USB Mirror Lamp▼: It can be connected to the power source via an adapter (Not Included!) or a power bank. NOTE: The USB vanity lamp will only turn on when power is connected and will remember the last light setting. ▽Adjustable Colors and Intensities▼: Dimmable mirror lamp with switch. Click the switch button to set 3 different colors (cold/warm/neutral). Click +/- button to choose different brightness (10 levels, 10%-100%) to meet different lighting needs. ▽Easy to Install▼: Using the included double-sided adhesive pad, you can stick the Hollywood makeup lamp on the mirror in minutes, simple and convenient. The cables don't fall apart, so the mirror stays nice and tidy. ▽Application▼: 10 bulbs mirror light is suitable for bedroom
