Testing light bulbs before buying them is a time consuming and inconvenient custom in Indonesia. We developed a series of packaging designs that allows new light bulbs to be tested in their boxes, so that they do not have to be removed before they're bought. The face of each packet was layered with an image that can only be seen by the brightness of the working light bulb. This makes for a fun testing experience as the graphics reveal different images and stories. As a result of our refreshed packaging design, Leuch'Tech gained a 2.7% market share in Indonesia.
