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.
Before starting any electrical work, always switch off at the mains. If in doubt consult a competent electrician
