Quadrangular bulbs
1988/02/01 Elhuyar Zientzia Iturria: Elhuyar aldizkaria
Philips launches a new type of bulbs. These bulbs have a quadrangular design. Thanks to this and the opalization of the ampoule, the emission surface is 400 times larger than that of the conventional transparent bulb. In addition, the light is distributed more evenly and the reflections are much smaller.
