While visiting the neighborhood ReStore, I found an ENTIRE CASE of NOS Philips 1000 watt /DX mercury lamps, never burned for $15. Date of Manufacture has them at September of 1988 so still quality lamps. Now, I plan on keeping two of them as my mid-60s M1000 has an H-36 ballast. So four of them are up for grabs. I will sell them at $25 each plus S&H. I also have four Sylvania 200/SBIF lamps at $10 each. PM me if interested.
