Lithium City-- A mobile light city with built-in energy source. Free from cables, light follows your heart.Lithium City- more than just lighting, it's an independent light and shadow unit with its own energy system. We have redefined the boundaries of "free creation": no need to search for power outlets, no need to calculate cable lengths, and no restrictions on power distribution. From then on, light can appear wherever it should be, whether it's in the center of the stage, above the audience, or in any creative corner that traditional wiring cannot reach. It lights up places that were once inaccessible. From the dark areas of traditional stages, to remote venues for tours, to temporarily built pop-up spaces; from outdoor filming locations for film and television, to safety-restricted areas in special venues - Lithium City truly frees lighting from the constraints of infrastructure for the first time. It is not only a technological innovation, but also a liberation of creative freedom. When lighting setup is no longer determined by the location of power outlets, and when creativity is no longer limited by cable lengths, the true revolution of light and shadow has just begun. Lithium City, a professional wireless stage lighting system, with built-in energy and boundless creativity, when the light breaks free from the last cable, the boundaries of the stage are defined by light itself.
