24 V linear LED luminaire in IP40 in a round, stylish aluminum profile with a diameter of only 0.79" (20 mm). 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' (2 m) open end black cable. Allows the use of 3 round covers in clear, diffuse and opal for soft light lines and 3 linear optics with 10°, 30° and 60° for precise light control. 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 h L80/B10. Embeds high quality japanese 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 = 91 / 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.
