24 V linear LED luminaire in IP40 in a round, stylish aluminum profile with a diameter of 1.5". Extruded and anodized aluminum housing profile and screwed aluminum end caps available in silver or black color. Can be surface-mounted or pendant and swiveled by almost 360°. 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 Chip Scale Package LEDs (CSP) a thermal resistivity of 5.33 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 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 (R9 = 85) 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.
