Every last bulb I used from the original batch and the replacement bulbs sent to me blew out within hours of installation. First I used them in my living/entertainment area. They burned out within a day or two when I asked the shipping company to replace them. I got a replacement and tried again only to get the same results. So I ended up ordering a different brand from a different supplier and they work great. So I took the original bulbs and used them in my garage and patio. The light in the garage burned out about a week after installation. I am very upset about this and done with this supplier and their lightbulbs.
