Difference between these Philips H11 bulbs?

[mclasser]

What does C1 vs B1 mean and what's with the difference in packaging?

EDIT: Mods please feel free to delete this thread. I just found the answer in the Philips catalog:

Philips suffix explanation:
B1 = Blister pack of 1 bulb
C1 = Commercial box packaging of 1 bulb
B2 = Blister pack of 2 bulbs

Blister pack is the cardboard backing with plastic front so you can see the bulb where they hang on hangers. The commercial packaging is more for like bulk purchases and putting them into a box or limited shelf spacing.
