Yes, my hydro store guy, gave it to me. He gives me a lot of stuff, I think the store is a cover for big grows. He charges me for stuff like, medium, lights, ferts and the such, but hardgoods, plumbing fixtures, thermometer, pH pin, and many other items. He is also very knowledgeable and doesn't try selling me a bunch a shit.
MY fixture has that same foot long cord, The extension plugs into the ballast and then runs into the tent and hooks to that 1' cord. I move it for two reason, one was the heat and I decided to move it outside the tent from the start, the second was for balance. Without the ballast the fixture and light are very light so easy to handle and manipulate.
When I start the next vertical grow I will off the reflector hood.
