24 V slim recessed linear LED luminaire in IP40 with a remarkable low depth of installation of 17.5 mm (0.69"). Extruded and anodized aluminum housing profile and screwed aluminum end caps available in silver, black or white color. Easy tool free installation with mounting springs. Delivered with 2 m (6.56') open end black cable. 9 diffuser optics and 3 linear lenses for recessed grazing, general or accent lighting application with minimal luminaire footprint. Light source assembled using state of the art automated Reel to Reel (R2R) production process supporting LED Linear™ Tj Away® thin flexible circuit board technology. In combination with ceramic LED packages a thermal resistivity of 16.3 K/W is achieved for an optimal heat dissipation (junction to profile) which guarantees an outstanding lifetime of &gt; 60,000 hrs L80/B10 for tunable white and 30,000 hrs for RGB. Embeds for tunable white centered high quality LEDs with 3 step MacAdams (SDCM3) binning on target CCT (One Bin Only) with an extended photometric code of Wxxx/339 ensuring an exceptional color consistency over the rated lifetime. Premium color rendition with a CRI of 85 and TM-30-15 up to Rf = 86 / Rg = 98 ensuring a remarkable light quality. Consistent light intensity all along the luminaire length is obtained thanks to active current regulation operated by dedicated integrated circuits (ICs) on each step. Protected against electrostatic discharge ± 2,000 V and polarity miswiring. Fully PWM dimmable for frequency &gt; 0 Hz up to 2 kHz (flicker free for frequency higher then 1.2 kHz according to IEEE P1789 standard). Engineered in Germany.
