System 161 lighting track is very narrow single lighting rail for walls, ceilings, cupboards and similar items and can be combined with existing presentation systems. The fittings are available in various shapes, colours and sizes. The special LSI halogen lamps do not cast circles of light on the walls; they are clear and warm. The front of the rail can be concealed after the fittings are mounted. Every fitting can be directed independently of the others. The lamps can be dimmed simultaneously. This system is affordable and can be installed by anyone.
