Luminaire head of the modular, decorative LED light column system. Version with clear PMMA cover. With autonomous power reduction via integrated evaluation electronics. Reduction of the luminaire luminous flux to 50% for a period of 7 hours (-2h/+5h), distributed around a daily new center of the duty cycle. The column system is designed for use in areas of terrain category 1 to wind zone 4. For attachment to compatible system standpipe. Compatible system standpipes available as a separate unit in various lengths and alternatively with a base plate or ground piece. The steel standpipes have a diameter of 193.7 mm. Optical system designed in multi-lens technology (MLT). Luminaire optics consisting of highly efficient, UV and temperature-resistant lens systems. With rotationally symmetrical, wide beam light distribution. Additional beam characteristics are available for flexible adaptation to customer-specific lighting tasks. Luminaire luminous flux and light color fixed, with luminous flux constant maintenance at the end of the service life (CLO). Rated luminous flux 4600 lm, rated power 37 W, maximum luminaire luminous efficacy 124 lm/W. Light color warm white, correlated color temperature (CCT) 3000 K, general color rendering index (CRI) Ra > 70. Color location tolerance (initial MacAdam) = 5 SDCM. Other LED light colors available on request. Average rated service life LCLO(tq 25 °C) = 100,000 h. The light source is replaceable in accordance with the ecodesign requirements (Regulation (EU) 2019/2020). Luminaire body made of die-cast aluminum Ø 193.7 mm. Color anthracite (DB 703). Coating suitable for marine weather on request. Luminaire height 1044 mm, luminaire diameter Ø 193.7 mm. Other colors and anti-graffiti coating on request. End cylinder made of clear PMMA. Luminaire body can be rotated horizontally by 360 °. No screws are visible in the connection area between the standpipe and the luminaire head. A design joint visually underlines the modularity of the light column system.
