Equipped with EXCELDON’s newly developed Mavis series "Four Great Kings" high-definition fixed-focus lenses with AK bayonet, it achieves micron-level precise light cutting and control. The shaped light for images is saturated, pure, uniform, and transparent with sharp edges.

Quadux A4 has rated powers of 14W, 24W, 28W, and 40W, with color temperature options of 3000K, 3500K, and 4000K. It features a 64mm filter bayonet, and comes with a full range of accessories including UV filters, color temperature conversion filters, as well as various optical filters such as red and blue ones, and 8-blade barn doors.

Quadux A4 adopts an offset-axis design with an overall diameter of only 64mm. It uses thermal-electric separation, supporting 360° horizontal and 270° vertical rotation (3-dimensional adjustment), and 15-second quick focusing and dimming.

Inheriting EXCELDON’s minimalist industrial design, it combines powerful functions with optics, mechanics, and aesthetics. It perfectly matches the architectural style of contemporary museums and art galleries, making it an essential equipment for precise light cutting, shaping, and refined lighting in museums and art galleries.
