"Push-up is a battery-powered, portable, and rechargeable table lamp. Pressing the top of the lamp raises it and simultaneously turns it on; pressing again until it closes turns the lamp off. A "touch" control is located under the base, which – when the top of the lamp is raised – allows for turning off, adjusting light intensity, and selecting the light color temperature. With a high protection index, the lamp can also be used outdoors. It has an electronic control system that monitors and signals the remaining battery life, allowing for optimized recharges and always performing them correctly. It is equipped with a contact charging base. Charger not included."
