Here's the new/old desk lamp I just bought... the Sadelite desk lamp. I replaced the ballast with
an Advance Centium electronic Rapid Start ballast (for F40T12s) that was in my kitchen fixture
(the Centium ballast was inside one of my kitchen fixtures when I moved in) and the Centium ballast seems
to work fine with the PL36w bulbs in my desk lamp. That Centium ballast will be replaced with a Magnetic Rapid
Start ballast though very soon. The computer chip looking thing next to this desk lamp, is the former ballast
that was inside this desk lamp before I replaced it.
