Lighting Products and Fixtures Design 5x5 LED Lamp by Barbara Princic The story about the 5x5 LED lamp comes together with the 5x5 chair introduced and awarded previous year. The chair's unique material characteristic required tiles’ dimensions of approximately 5x5 cm. Therefore the same dimensions were the starting point for the lamp. In order to avoid the direct form's repetition the 5x5 cm is applied in a form of rhombus, the main modular structure part of the lamp. Several lamps mounted together offer the possibility to create different lighting patterns like zig-zag, diagonal line, the shape of an arrow, or other shapes by using designer's own creativity.
