This lighting fixture is both a scale and also a lamp. Its luminosity depends on the weight of the object placed on top of it. The heavier the object is, the brighter the lamp. Designer Junji Kawabe created the light=weight lamp to allow the illumination to be controlled by gravity.

The unique concept essentially allows users to control the amount of light down to the very last gram. By adding and subtracting weight, users can find the perfect place of light and dark.


The table lamp is developed using a simple spring-loaded mechanism that enables it to adjust the brightness of the bulb. Kawabe explains that:

Light, weightless thought it may be, “weight” of indirect matter and consequences always exist: resources and material, lives of people who extract them, by-products released to environment… with a lift, we feel the “weight” of light.
