"GE Alto" F32T8/U6 U-Bend 3500K Fluorescent Lamp

Here is possibly the most cursed light bulb in my collection currently. It is a GE F32T8 fluorescent U-bend lamp with green end caps! It's quite obvious that GE had these lamps manufactured by Philips with their name on them, and Philips used their infamous green end caps by mistake. This Mod-U-Line F32T8 lamp has a 6" leg spacing. It is tri-phosphor 3500K (SPX35). If anyone can decode the date code for this lamp, it would be highly appreciated. It is definetly quite recent since it uses GE's current etch.
