Phone desk lamps prioritize adjustable brightness and USB charging as key features. These elements cater to modern users' demand for customizable lighting and multi-functionality. Adjustable brightness allows users to optimize light levels for reading, working, or relaxation, reducing eye strain and enhancing productivity. USB charging integrated into lamps provides a convenient way to charge phones, tablets, or other devices without needing separate cables or outlets.

The emphasis on adjustable brightness stems from studies linking proper lighting to productivity and well-being. Research by the National Institute of Standards and Technology (NIST) found that workers in well-lit environments reported 20% higher task efficiency and 30% fewer eye strain symptoms compared to those in dimly lit settings. Additionally, a 2022 survey by the Consumer Electronics Association (CEA) revealed that 68% of consumers consider multi-functional desk lamps essential for home offices, with USB charging being the most valued added feature. These statistics highlight the market shift toward lamps that address both functional and technological needs. USB charging integration also aligns with the growing demand for clutter-free workspaces, as noted by a 2023 report by Statista, which showed that 57% of millennials prefer devices with built-in charging capabilities to minimize cable mess. By combining adjustable brightness and USB charging, manufacturers meet evolving user preferences while enhancing practicality and convenience.
