Three years ago it was all about CFLs....now it's LEDs. It's all changing quickly, but as said with a conventional fixture, you can change lamps or LEDs or what ever is next.
That is what I did in our kitchen.
When we moved in here almost 8 years ago, I replaced the incandescent BR30 bulbs with CFL versions in the recessed cans to save a bit on the electricity. The CFL bulbs are the same color (soft white/2700 K) as the old incandescent bulbs, which was nice. The downside was the CFL's took about a minute to come on full bright.
Fast forward 7 and a half years and I found a great price on some BR30 LED bulbs that were the same color temperature and lumen output as the CFL bulbs, so I bought the LED's and put them in there.
Now I have instant on brightness and the LED's are using even less electricity than the CFL's. And the LED's even work with the dimmer switches that were in there just like the dimmable CFL's did.
And all I had to do was unscrew the old bulbs and screw in the new ones.
