Designline Tube Kit 3 Ceiling Lamp 1m Black is a complete rail system that brings flexibility to your lighting. The system comprises a rail and a spot for mounting on the ceiling—at home, at the office, or in your gallery. You connect the system to your lamp socket, and then you attach your spots wherever you see fit. You can change their positioning whenever you see fit.
Choose from three different complete sets:

Designline Kit 3, 1m – 3 ceiling spots with a 1-metre rail, incl. start piece

Designline Kit 3, 2m – 3 ceiling spots with a 2-metre rail, incl. start piece

Designline Kit 4, 2m – 4 ceiling spots with a 2-metre rail, incl. start piece

All rail sets are available in two colours, black and white, and two different spot designs, Tube and Bell. If you want to expand your system, you can buy more rails, connectors, pendants, and spots.
If you need to add more rails, note that you need a Connector to combine the rails.

NB! The start piece is placed at the end of the rail, not in the middle. If you want to connect electricity to the middle of your rail, you can combine the two rails using a Designline Center Start
