- Adjustable Clips: The rechargeable night light features adjustable clips that grip objects of different thicknesses. A small segment on the clip tail can be rotated independently, expanding the clamping range and keeping clips firmly attached to items. - Bright, Versatile Lighting: The LED lights on the battery-operated clip-on unit are as bright as three standard LEDs. The dual-arm switches allow multiple configurations: a single light on, lights on both arms, two lights on a single arm, or all lights on both arms. No flicker, shadow, or glare, designed for comfortable reading. - Flexible Power Options: The book light supports multiple power modes, including AAA batteries or USB power. When connected to power, you can plug into a DC plug to substitute the power source, and the battery power is automatically cut off without removing the battery. When unplugged, battery power resumes with a simple press of the button. Package does not include battery (three sections). - Durable, Adjustable Arm: The light arms use a quality metal alloy for high flexibility and hardness. They can be set in any position and adjusted to the desired angle, providing full-range, multi-angle lighting. - Use Scenarios: Ideal for nighttime reading in bed, illuminating a desk for study or work, and providing directed light for crafts, sewing, or hobby projects without disturbing others.
