Philips TL-D 58w/830 Warm White

Rescued today from the recycling bin, this brand new Philips 58w 830 warm white. Date code 6D = April 2016, I think this is the newest tube I own and also I think the first triphosphor warm white 5ft?

There was another tube next to this in the same sleeve, but it was actually a heavily banded Osram tree in the sleeve that I suspect was dead so I left it. No idea why this one was in there, it works fine and is new.
