Larry: The first picture below is May 29th, 2014. The second is from this year, today, May 28th, 2015, one day short of exactly one year later. It isn't as bad this year, but compare it to the one above it--that's normal. Sometimes I think the age of the bulb might have something to do with it.
I came across this picture in my folder that somebody had posted last year. Is this the one we talked about last year by chance?
