Coffee Mug LED

The mug is next to our coffee maker; the overhead light is reflected in about an inch of black coffee  at the bottom. LED stands for light-emitting diode (which I had to look up :). LED bulbs are much more efficient and last longer than traditional incandescent bulbs, which they have extensively replaced over at least the last decade.  Good to combat climate change! The main outing today was to renew a couple of CDs which had come due--interest rates are going up and, and the stock market does not seem happy.
