Can anyone decipher the Iwasaki EYE Date Codes.?

We have a US spec 100W SBMV with the date code of 08B on it, can anyone help.? 

I think 08B might be February 2008 at least from when I guessed the date on my lamps. There's a PDF with another of their date codes but it's in a different format.

Is it that simple,? We'll go with that date until somebody tells us otherwise. 

I'm not exactly sure but it seemed to make sense for the lamps I have...They were dated a few months to a year prior to my purchase of them and I got them more or less brand new at retail.
