24 V slim linear LED invisible downlight luminaire in IP40 with optimal glare control available as recessed with a remarkable low depth of installation of 1.3" or surface-mounted &amp; pendant version in a robust 1.65" x 2.44" housing. Extruded and anodized aluminum casing profiles and magnetic aluminum end caps (for surface and pendant) available in silver, black or white colors. Easy tool free recessed installation with pre-mounted springs. Delivered with 6.56' open end black cable. Nanometric lenses optics technology enabling accurate 15°, 25°, 40° or 65° beam angle gaussian lighting distribution. Antiglare optics available in black or white offering a UGR as low as &lt; 13 for an optimal visual comfort. 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 CSP LED packages a thermal resistivity of 5.3 K/W is achieved for an optimal heat dissipation (junction to profile), which guarantees an outstanding lifetime of &gt; 60,000 hrs L80/B10. Embeds high quality CSP LEDs with 3 step MacAdams (SDCM3) binning centered 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 95 and TM-30-15 up to Rf = 95 / Rg = 100 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). Made in Germany.
