Lovely concept this.

The weight of light is by definition something hard to quantify or experience with human hands, but this new project from Studioroom906 explores the idea very nicely indeed.

By associating light to weight, their 'Weight of Light' lamp provides the user with a new experience allowing control over light in a more haptic way. Combinations of simple mechanisms utilise gravity resistance to transfer light to a bulb and for every 100 grams of weight, a corresponding 10 watts of light is produced.

When you put more weight on the lamp, it get brighter, and with less weight, the lamplight becomes darker.

Much more fun than a plain old dimmer switch...
