I switched to LED for my 20 outdoor Malibu path lights a couple years ago.
Not nearly as bright as incandescent, but just adequate to light the path. I had been testing options for a few years, and switched when I could get ones that were bright enough to see were on, and for $5 each.
The biggest advantage is that they never burn out, literally so far. I was constantly replacing the incandescents (I don’t think they liked occasionally being buried in snow), which always had a few that needed replacing, and which turned their glass dark gray over time.
I must have gotten a wrong batch when I bought some to try out a year or so ago. They all burned out!
Meanwhile, I’ve a 75 watt U. S. made bulb that has been burning in compliance with the fire laws governing condominiums for over six years.
