The three lower cylinders have three light bulbs and their intensity can be changed by pulling or pushing the three upper cylinders. Them three can work independently depending on the needs. The idea was born from a pesonal need, because I share my bedroom with my sister and in many ocassions it is very discomfortable the light on in the night, for example when I’m sleeping, or in other ocassions it is discomfortable for her the light on when I’m studying late at night…” – Link.
