Thanks, I think the Lifeline XL was made by Sylvania Canada only though. Not sure what the XL meant but the Lifeline was meant to be Sylvania's longer lasting premium line, sorta like the Mainlighters.
I also replaced the Mark III ballast in the fixture with a full power 0.8A Philips ballast which runs the lamps much brighter than the MK III.
