Designed by Pia Guidetti-Cirpa, the P428 ground lamps are another example of the charm of simplicity. A circle, a cylinder, a sphere and nothing more: this is today's recipe, and our appetite is fully satisfied. The generous opal spherical diffuser is safe on the lower half of a chrome semi -sewer and can be raised to reveal the three contained bulbs. The reason why there are three becomes evident when playing with the lamp switch, which acts as a dimmer and turns off or slowly lights the bulbs, one by one. The lamps are in excellent condition and have been falling back to use them and admire safely.
