FL 555 ROUND surface-mounted luminaire with high-performance LED. Luminaire output 50W. Advanced surface luminaire creates an unprecedented symbiosis of general and workplace lighting. Particularly delicate and innovative design. Characterized by clear and round shapes, a harmonious integration into the ceiling and surroundings is created. Particularly elegant and architecturally supportive. Designed for a wide range of application and planning variations. Luminaire frame made of die-cast aluminum. Scratch-resistant surface finish thanks to high-quality powder coating. Prismatic light optics with LED side light feed. Integrated, highly transmitting light guide made of PMMA. Direct beam with corona to brighten the ceiling. Homogeneous luminance distribution across the entire light emission surface (LED side light technology). Ceiling brightening in the room using an indirect component of around 3% (corona). Glare-free microprism cover ensures an attractive room atmosphere. High light quality supports demanding visual tasks.
