Lightweight pendants can be suspended from cable. Some pendants come with the connecting components already part of the pendant. Any of the Tech Lighting pendants that have a product number starting with 700K can be used on cable without an adapter.
You can also adapt lights for other systems to work on cable using a Freejack connector from Tech Lighting or a uni-plug adapter from Bruck Lighting. Because the cable is the same size, the lights are compatible. However, if you want a very consistent look, choosing lights all from the same company will make sure they all have the identical finish.
Using the Tech Lighting Kable Freejack Connector, you can put any pendant made by Tech Lighting on cable. It is best to stick with light weight pendants. If the pendant is too heavy, add additional supports to the cable run.
These are just some examples. Tech Lighting makes a lot of pendants in various colors and options that are compatible with cable lighting systems.
