and reduces CO2 emissions by 9,070 pounds over its life

The question is, of course, what is "its life?" There's a huge market difference if the LED costs $30 but lasts 1 year vs. 10 years.

LEDs have a life time of approx. 11yrs. of constant use.

LED’s last ages... I forget the exact ratings on them, but I have personally yet never seen an LED burn out, and I’ve been using devices with them for 20+ years. If their life expectency isn’t measured in decades I’d be amazed.

The question is, of course, what is "its life?"

Answer my own question from the press release: "they last 50,000 hours before needing to be replaced." Under normal use (say, 8 hours/day), the LED should last 15 years or more.

By comparison, an incandescent bulb has a lifetime of 750–1000 hours. (Though for some reason, the overhead lights in my house burn out much faster....)

Factor in electricity savings, and a few strategically-placed LEDs could be a long-term savings. I can't see replacing every bulb in my house, though.

LEDs, the last spec.’s I looked at, had a mean time between failure (MTBF) of over 450,000 hours; approximately 51 years.

Enough for you?
