G20 and G25 globe lights offer a bright, bold look for decorating indoors and out. Use LED globe string lights on your Christmas tree or to set off your outdoor decorations. LED globe lights come in a range of colors and bulb styles for a dramatic look. At 25mm, a G25 light bulb is roughly the same diameter as a quarter - an ideal size to add energy to your Christmas display. Furthermore, you can update your C7 light strings with interchangeable G20 Christmas lights for a modern look!
