I have 7 fixtures where I use this type of lamp: 4 outdoor spotlights and 3 indoor spotlights over two showers and a bath. I first ordered a box of 6 in October 2019 and used the last bulb in box #2 a few weeks ago. That's 12 lightbulbs for 7 lights in 24 months. The outdoor lights are turned on daily from sunset to 10 p.m., while the indoor lights are used in a normal household. I am very satisfied with the performance of these lamps.
