This listing is the Lotus LL4RR-5CCT-BK together with the 120-347V 0-10V Dimming Driver option: one product that includes the base fixture and the option, so nothing else needs to be ordered for it. The base fixture is described by Lotus as 4" Round Plenum-Rated Regressed LED Downlight 14.5W 5CCT 90 CRI Black.

The standard 120V TRIAC dimmable driver that normally comes with the base fixture is replaced by Lotus driver LLL-LD1535TR. It accepts 120V to 347V AC input and dims with a 0-10V control, so the fixture can be used on commercial 277V and 347V circuits as well as 120V. It is part of this one product. Everything else matches base part number LL4RR-5CCT-BK.
