The Sylvanias here are dated 10/11. The date code here is a standard Osram system, which is not used by the USA Sylvania plant. I was surprised to see this, these are the first Sylvania GLS bulbs made overseas ever since 1901 when Sylvania's earliest root began. I looked in Family Dollar, they have some full wattage Sylvanias, but are all USA made. The French bulbs were sent to me by a friend in MA. Ok I will shut up now lol.
