Here is an article from Maxim describing the longevity of electrolytic capacitors in conditions which require high temperatures. As well as some pointers in LED light bulb design.

Electrolytic capacitors are notorious for short lifetimes in high-temperature applications such as LED light bulbs. The careful selection of these devices with proper interpretation of their specifications is essential to ensure that they do not compromise the life of the end product. This application note discusses this problem with electrolytic capacitors in LED light bulbs and provides an analysis that shows how it is possible to use electrolytics in such products.
