Linear system, consisting of flexible printed circuit boards with highest intensity SMD LEDs 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. It also features PWM elements to allow control and dimming. Supplied cut to size (minimum piece of 100 mm), inserted in an 14,5 x 7,5 mm transparent polycarbonate tube with ultra-adhesive tape double sided, 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 per unit: 6 m.
