Led boards for indoor lighting. The strip equips high energy efficiency white LED, with warm or neutral colours and good colour yield (CRI min 80). The system incorporates constant current controllers in order to optimise the brightness and reliability of the LEDs. The LED module is 481.5 mm long and can be adjusted every 60.2 mm with a continuous light effect. It houses pressure plug connectors to simplify board pairing avoiding manual tin soldering.
