Ordered several at the end of July 2018. One already burned out. Lifespan of 11 years with daily use of 3 hours. Hasn't been used much. Even if it's running 24/7, it shouldn't burn out anytime soon. Installed once and never moved again. Of course, he died shortly after the one-year warranty expired.
