I'm looking forward to returning to California to visit my parents next Christmas and seeing all the fluorescent Christmas lights on the tree.
How quaint.
I saw lots of nice LED lights for Christmas trees last year. My wife purchased 2 strings of them to run up the bannister and handrail in the front room. We left them in place and leave them on 24x7. No appreciable heat, an exceptionally long life and a big improvement in safety when wandering downstairs late at night. We also have an 18" LED light bar over my wife's desk in the kitchen. The light tends to be a bit "blue/white". Adequate for reading a book.
My wife may acquire some pastel LED lamps as we approach Easter. Red, white and blue will likely adorn the area in June.
