Query: Bought the 8 pack, one defective, one dead after 5 months.

Overall I am pleased with the quality of the product. (Not sure why there was a defective bulb inside...) Have been using the other 7 bulbs for five months, and all perform well except one that I put on the balcony. I think the cold temperature may have killed it. Great product for the price (less than $1 each).
