LED optical illusions are at the heart of modern lighting by Studio Cheha. The Tel Aviv-based design studio has made its name with a range of lamps that are flat, but look entirely three dimensional. Using a process called bulbing, Studio Cheha has perfected a process by which a design is etched into a piece of flat acrylic glass, and the etched image is replaced with LED lighting. Energy efficient and long lasting, these innovative modern lamps are also easily interchangeable, each design fitting into a standardized base.
