Light arm design and function Light arms are made from 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 options. Adjustable clips and grip The adjustable clips can grip objects of different thicknesses. A small part on the clip tail can be turned independently, expanding the range of clampable objects and helping the clips stay firmly in place. Brightness, control, and versatility The LED lights are as bright as three common LEDs. The dualarm setup offers multiple configurations: on a single arm (one light on or two lights on), or on both arms (one light on each arm or both lights on). The lights operate with no flicker, shadow, or glare, making them suitable for reading. Power supply options These clipon lights support multiple power sources, including AAA batteries or USB. When connected to a DC power plug, the battery power is automatically cut off. When unplugged, the device runs on battery power again; simply press the button to turn on. The package does not include batteries (three sections). Use scenarios Reading in bed at night without disturbing others. Clipping onto a book, notebook, or recipe page for hands illumination during study or cooking. Clipping to a desk edge or shelf to illuminate a work area for crafts, writing, or exams.
