Be careful what you wish fora ! I volunteered to check out a new line of LED dimmable household bulbs from OSRAM SYLVANIA, wondering at the time where I would test them. Almost immediately, light bulbs that had lasted fifteen years began to burn out all over the house! I no longer had to worry about test locations, but rather whether these bulbs would prove worthy enough that I would go buy more of the same to fill my empty sockets.
