J = Factory, I think it's Winchester, KY
6 = 1996, 2006, 2016, etc. You'll need to know what the lamp has that makes it a certain year.
2 = February
8 = Twelve month cycle (1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c - with a, b, and c being October, November, and December)

If 2 is february, then is there also a 12 months cycle with an 8? i'm confused about that part. :wndr:

The 8 indicates that it is a twelve-month cycle. Not sure why it is. There's another variation of the date code style (mainly on their fluorescents) that is weekly. Used to decode lamps with it but I don't remember it. That one is a little bit more complicated.

Hi Max, if the J is underlined, then it indicates Juarez in Mexico.
This particular datecode is detailed at the link here.  Maybe it is confusing that I filed that sheet under the section for Osram datecodes, because it ran during the time when Sylvania North America was owned by Osram.

Thanks James, forgot that osram owns sylvania! :-[ The Juarez plant made mains halogen lamps like the one i have, so it looks like it checks out. 8)
