To be honest, most cable lighting systems rely on LED technology. Either in the form of permanently installed LED boards - often in combination with a minimalist design - or with standard sockets.
And some manufacturers already supply the appropriate LED lamps, e.g. LEDs with GU5.3 / MR16 bases for a spot-based system.
LED technology is not only energy-efficient, it’s durable too, meaning cable lighting systems are generally maintenance-free once they’re installed.
It should be noted, however, LED-based cable lighting systems aren’t always dimmable, so make sure you check the product details before purchasing.
