Linear system, consisting of flexible printed circuit boards with highest intensity 60 LED/m SMD and widest beam angle. Additionally, the electronic circuit features different protective components, against reverse polarity, against voltage peaks and for the maintenance of the current supply through the circuit in case some anomaly occurred. Supplied cut to size (minimum piece of 116mm), inserted in a transparent polycarbonate tube with sealed at both ends and a side cable connection. Suitable for linear, curved or not, cove lightings and architectural lightings where a higher performance is required. Maximum length 6 m until 8 m interconnected.
