RIDI-TUBE LED light source, color rendering Ra >= 80, color tolerance < 3 Step Mac Adam (initial). LED modules designed as linear boards. Mid-power LEDs for even illumination and maximum efficiency. Base profile made of extruded aluminum for optimal thermal management. Linear board continuously interlocked with base profile over the entire length. Cover made of satin PMMA for efficient light extraction, socket made of robust white PC. Operation with an external LED driver (built into the light), constant current, protective extra-low voltage less than 60 volts (SELV-compliant). RIDI-TUBE packaged. Length 1450 mm, power consumption 27 watts. Color rendering Ra > 80. Light color 3000 (...830...), 4000 (..840...) or 6500 Kelvin (...865...). Assembly: Factory assembly of the electrical components in almost all lights from the RIDI range. Tool-free on-site installation of the RIDI-TUBE similar to fluorescent lamps.
