Yes, cooling is important. I don't have a passion for lamps so after 5 years in a new house most of my LED bulbs are still hanging from the ceiling and walls, I can't remember any failure.

I had an IKEA lamp with a pretty tight fitting for the bulb and it killed LEDs after a few months. I reverted putting a fluorescent bulb inside it. No failure.

I would say most LED bulbs. You need ones specifically rated for enclosures, which are way less common, and most people have the wrong idea of what counts as enclosed (the glass hood around your kitchen chandelier bulbs is an enclosure, as are ceiling cans)
