PICK / lighting


when it became darker suddenly, the pupils of your eyes dilate to let more light. this phenomenon is called Adaptation.
it takes some time to adapt to sudden darkness. for that reason, we have difficulty in securing a clear view and feel insecure after turning off the light. And It is possible that we bump into stuff scattered in the room.we designed "lighting" using a switch cover. it can be used as flashlight while we walk to bed in the dark after switching off the light.
Also, we can use this lighting as a emergency light.
