Looking to upgrade your Hydrofarm lighting system with a new reflector, but not interested in their models? No problem! Enjoy the flexibility of upgrading your light with any one of the great reflectors that we offer using this simple socket-to-ballast adapter. The “Hydrofarm to HYL” adapter connects reflectors or socket sets with the universal socket plug type to the unique Hydrofarm-type ballast receptacle. The male end plugs into the Hydrofarm ballast, and the female end accepts the universal-type socket plug.
