LED light source RIDI L-TUBE-B, 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 solid aluminum for optimal thermal management. Linear board continuously interlaced with base profile over the entire length. Cover made of clear, satin or opal PMMA for efficient light extraction, end cover made of robust PC, color-coordinated with the cover. Operation with an external LED driver (built into the light), constant current, protective extra-low voltage less than 60 volts (SELV-compliant). L-TUBE-B packaged. Length 1450 mm, power consumption 26-58 watts. Color rendering Ra > 80. Light color 3000 (...830...), 4000 (..840...) or 6500 Kelvin (...865...). Installation: Factory installation in industrial and sports hall luminaires from the RIDI range. Tool-free, mechanical lamp replacement of the L-TUBE-B by loosening the connection-side snap-in connection of the spring steel clamp and longitudinal displacement and electrically via socket-plug system.
