I'm assuming you looked at the cords and they're different kinds of plugs, and yes they sell adaptors that bridge the two, no idea what they're called but i bought one at my local hydro store.
Ballast hasn't arrived yet but the plug is like a bar and round plug next to eachother, and then another round plug below and away from the other two I don't know what the ballast plug looks like...
Both Sunlight Supply and HydroFarm sell Lumatek. Lumatek manufactures ballasts with both Sunlight and HydroFarm cord sets. If you ordered through HydroFarm and have a Sunlight reflector (or vice versa) you will need an adapter. Hope that helps.
Just send your Lumeteck back and get a QUANTUM BALLAST lumetec still uses there old technogely im tellin ya quantum is better and they have WAYYY better customer service thats not even up for debate.... Just my opinion though
