AND if it's in a very cold place, like a shed or back porch, ferget it! They won't come on at all!............
We’ve noticed that as well. It seems if there is moisture in the area (bathrooms, outdoor lighting etc.) these things never get to full power and stop working completely long before a regular bulb would. It’s a total rip off.

Define very cold. I’ve got them outside my garage, and while they do take a little while to warm up and produce full light output, they work fine - and have for several years now. The temp here last night was close to 0, and they were working just fine.
