Product Features
Brighter & Eye-Caring Illumination
The Glocusent A31 features 72 high-quality LEDs, providing a wide and even light distribution. The design minimizes flickering and glare, and includes a shade to prevent direct light exposure to the eyes. The light gradually brightens and dims upon activation or deactivation to assist eye adjustment in varying light conditions.

Strong Clip & Flexible Gooseneck
The lamp features a robust clip designed to securely attach to surfaces up to 2.36 inches (6 cm) thick, such as headboards, desks, or tables. Soft padding on the clip prevents surface damage. The flexible gooseneck, constructed from durable metal and silicone, allows for 360° adjustability and maintains its position once set.
