Here is a keen lamp you may want for your home, one that comes with a dimmer switch. But mind you, the dimmer control is not similar to the common ones wherein you simply adjust it by moving them or rolling them in a particular direction.
Rather, the Light=Weight Lamp would rely heavily on gravity to give you the proper illumination as you would want. The lamp actually looks pretty close to a weighing scale although without the numbers or needles to point actual weights.
The upper part is used for holding various objects with various weights, something which apparently accounts for the amount of lighting you would want. Hence, with some grams or pounds, you can easily manage the proper mood and ambiance from this lamp designed by Junji Kawabe.
