Gate B Seven gallery spotlight - versatile component of the check-in system The matt silver-coloured design of Gate B Seven suits a wide variety of Raumgestalt. The track spotlight is just one of the many components of the world's smallest single-circuit track lighting system, whose narrow aluminium track measures just 20 x 8 mm, meaning that it really can be installed almost anywhere. The swivelling head makes Gate B Seven the ideal choice for adequate lighting in museums, galleries, restaurants and private homes. The elegant design can also be emphasised by a decorative ring available as an accessory.
