Short bulb life

I bought these expecting long bulb life being LED and the claims made by the manufacture. About 8 months after buying them the first one faded to a dim light. Now a little over a year the second one is doing the same thing. Disappointed and hope the seller will replace these, maybe they are defective. I have similar Outdoor LED lights that stay on 24 hrs a day 6 months out of the year and are going on 5 years with out a problem, so I know it's possible to have much longer life.
