In the DC String LED solution, the AC/DC converter, which takes up a lot of space, is separated from the conventional LED Driver and is installed at a higher-ranking central location, from where it can supply LED light sources with a total output of up to 150 W in an energy-efficient way.

The DC-String system is available for fixed-output and dimming applications and can be combined with any LED module. Small PCBs for fixed-output or DALI dimming can either be integrated into the luminaire or the track adapter. No additional DALI lines are needed and therefore the track infrastructure can be reduced in size.
