These bulbs last 2-3 years under moderate use. Buyer beware.

22 years is extreme exaggeration. I bought in October 2014. 3 years later in Nov 2017, only 1 of 3 is still working. This is under indoor conditions and being used 3 hours per day. I don't turn on & off very often either. 1 failed in around 2 years and another bulb failed recently. I don't recommend at these high prices.
