2. Product Overview & Features
The Glocusent A102 book light is designed to provide optimal illumination for reading, featuring advanced LED technology and user-friendly controls.
- Wider & More Even Illumination: Equipped with a 150% larger lamp head and 12 upgraded LEDs, this light delivers broad, uniform lighting. A high Color Rendering Index (CRI ≥90) ensures natural color appearance. It is engineered to be free from harsh glare, dark spots, and flicker, promoting eye comfort.
- Adjustable Brightness & Color Temperatures: Offers 5 stepless brightness levels (3–60 lumens) and 5 color temperatures (1800K/2500K/3400K/4500K/6000K). The 1800K amber mode filters out 99.9% of blue light to protect eyes, while the 6000K crisp white light is suitable for detailed work.
- Extended Battery Runtime: Features a built-in 650mAh battery providing up to 100 hours of light on a single charge, allowing for prolonged use without frequent recharging. Four clear power indicators display the current battery level.
- Durable & Ergonomic Design: The 110° light angle minimizes light spill, ensuring private reading. Quiet buttons prevent disturbance. The lamp head can be adjusted 90° left/right and tilted 60° down for precise illumination. Constructed from strong ABS material with smooth hinges, the clip securely attaches to books of various thicknesses without causing damage. It can also function as a mini desk lamp when freestanding.
- Portable & User-Friendly: Weighing only 1.8oz and folding down to 0.58 inches, it is highly portable for travel. The intuitive 3-button interface allows for quick adjustments, even in low light, and a smart memory function recalls your last settings.
