And do you keep your bulbs on 24/7? The mass market, "budget" (really, the baseline bulbs that most people buy; ~$1.25/bulb) LED bulbs are usually rated for around 10,000 hours of on-time (which is ~1.14 years).
The mass market, higher end bulbs (namely from Cree; ~$2.50/bulb) are rated for around 20,000-25,000 hours of on-time (~2.28 and ~2.85 years, respectively).
