They DO NOT last 30,000 hours! I bought 2 packs (30 bulbs) of these bulbs 17 months ago. 8 of them stopped working completely and 2 others are almost dead. Even if I ran 8 hours every night, that would only be 4,000 hours at the moment. I think I'm actually somewhere around 1500 hours. In any case, they do not meet the requirements. I have several lightbulbs that I use in a similar way and none of them have burned out yet.
