A new interpretation of the classically built luminaires for wall and ceiling mounting with a pre-installed, powerful LED module. Available with a silver-grey housing colour, the BIRO has frosted round glass, which guarantees homogeneous light distribution. With protection class IP44, this luminaire is also designed for use outdoors. Thanks to its pre-installed LED driver, the BIRO is ready for direct connection to the 230V mains supply. This luminaire contains built-in LED lamps.
