I think I only have LED left. Due to the shift work, essentially, some lights run 24/7, and, most are on dimmers to boot....so CFL's struck out.
The hardest to replace were some candelabra style that went into some chandelier style lights...as it was very difficult to locate teeny-based versions that put out about the same lumens as the incans they replaced.
I got pretty close though, and the quality of the lighting has been great.
Back when running incans, bulb changing was a constant chore...SOMETHING was always burned out...because there are so many lights.
Since going 100% LED, I only changed ONE, total, in the past year, and that one was bad the day it went in...so, I'm not sure how to count it (Flickered on install, took it back)
The electric bill dropped precipitously too, which was nice.
