Metal Halide Grow Light/Ballast Extras

Package of grow room stuff. I have a 400w XtraSun Metal Halide Ballast, (2) Hortilux Blue Metal Halide bulbs, a cylindrical grow light tube (fits onto cooling duct for fan attachment), a Green Air Products CT-DH-1 Atmosphere Controller, and a Hanna 9813 Gro-Check PH meter.
I`ve had it all in storage for a few years, I have tested the bulbs and ballast and are still working perfectly. I don`t know about the atmosphere controller or PH tester, but they were working fine when I stored them. $300 OBO
