1. Adjustable Clips The rechargeable night lights feature adjustable clips that can grip objects of different thicknesses. A small part on the clip tail can be turned independently, which increases the scope of clamping objects and helps the clips stay firmly on items. 2. Meet Your Multiple Needs The LED lights attached to the battery operated clipon lights are as bright as 3 common LED lights. The switches on the dual arms allow flexible configurations: a light on, a light on both arms, two lights on a single arm, and all lights on the double arms. The design provides no flicker, shadow or glare, making it suitable for reading and other tasks. 3. Multiple Power Supply Modes The book lights for reading at night in bed support multiple power sources, including AAA batteries or USB cable. In the power supply state, you can directly insert into a DC plug to the power supply, and the battery power will be automatically cut off without removing the battery. When unplugged from the plug, the battery powers on again simply by pressing the button. The package does not include battery (three sections). 4. Durable, Flexible Arms The light arms use a quality metal alloy material with flexibility and hardness, allowing them to be set in any position and adjusted to the required angle and shape, providing a full range of multiangle lighting options. Use scenarios Reading in bed at night or studying on a desk without disturbing others. Crafting, knitting, or DIY tasks that require targeted, glare light. Travel or camping, clipping the light to a headboard, notebook, or luggage for portable illumination.
