Light arms and construction The light arms are made of quality metal alloy for flexibility and hardness. They can be set in any position and adjusted to the required angle and shape, providing a full range of multiangle lighting. Adjustable clips Rechargeable night lights with adjustable clips grip objects of different thicknesses. A small independently turnable part on the clip tail widens the clamping range and helps clips firmly grip items. Versatile lighting for multiple needs The LED lights on the batteryoperated clipon lights are as bright as three common LEDs. The dualarm switches offer flexible configurations: one arm on, both arms on, two lights on a single arm, or all lights on both arms. No flicker, shadow, or glare, with a design intended for reading and other tasks. Power supply options The book lights support multiple power modes, including AAA battery operation or USB cable. In power mode, you can plug into a DC plug to the power supply, and the battery power will be automatically cut off without removing the battery. When unplugged, the battery powers on again with a simple press of the button. The package does not include a battery (three sections). Use scenarios Reading in bed at night. Clipon lighting for a desk, study, or crafting tasks. Travel, camping, or bedside lighting where a compact, clipon light is convenient.
