The light arms are made of high-quality metal alloy with excellent flexibility and hardness, allowing them to be positioned at any angle or shape as needed, providing versatile lighting options from multiple angles. Multiple Power Supply Options: These reading lights offer flexible power sources, including AAA batteries or USB cable connection. When connected to USB power, the device automatically switches to direct power mode and cuts off battery supply without requiring battery removal. Upon disconnecting the USB, the light seamlessly reverts to battery power—simply press the button again to resume. Batteries (three AAA, not included) are required for battery operation. Meets Various Lighting Needs: The LED lighting system delivers brightness equivalent to three standard LEDs. Independent switches on each arm allow for customizable lighting: single arm on, both arms on, one light on a single arm, or all lights on both arms. Flicker-free and shadow-free illumination ensures comfortable use for reading or detailed tasks. Adjustable Clips: Designed with adjustable clamps that securely hold objects of varying thicknesses. A rotatable component at the clip base enhances grip range and stability, ensuring firm attachment to different surfaces. Wide Range of Applications: Ideal for use on music stands, books, pianos, in orchestras, during performances, at workstations, computers, and in crafting, knitting, or sewing.
