SPACE SAVING: This superior, space-efficient design is perfect for small desks or tight areas lacking a convenient power outlet. The foldable LED desk lamp ensures brilliant light for up to three hours on a single charge. DIMMING SETTINGS: Activate the lamp with the main switch adjacent to the charge port. A simple tap on the palm icon at the base powers it on. Tap again to cycle through color temperatures, or press and hold to fine-tune the brightness to your comfort level.
