I cheaped out on some LEDs bulbs ("edison" form factor) and my biased opinion is that they mostly lasted about a year. Bought some brand name ones recently and so far (~2 years) they are doing ok; I can't recall having replaced any since I bought them, but I only replace them when they're out. If there's room, I write in sharpie when I do it so I can see how long they go. My CFLs are often in the 5-8 year range.
