Yes it's true, a transparent lampholder.  Works well with transparent cable.  This lampholder has a threaded skirt, so if you did want to attach a shade (transparent I presume), you can. Important to note this lampholder clamps onto a cable.  It cannot be used on table lamps or chandeliers.

For use on pendants
