Cor de Ruijter presents an led light bulb with 5 mm leds. It has the form of a light bulb. This lamp is in an experimental phase and the sample was a proto sample. This phase is used to confirm the applicability of a unique concept of this lamp: the used transformer in this lamp is changed by a patented circuit. Advantages according to the producer: easier design bringing a cheaper production process, lower energy usage and longer lifetime because a transformer is not used.
