I have a couple of the older American made CFLs that I like just fine. The ones coming from China are pure crap and half the time they don’t even work right out of the package.
The LED lights are nice but damn expensive.
I replaced a couple spots (incandescent) with LED spots. The LED light is very blue and the load is completely wrong for the dimmer. LED needs to be controller with a PWM style of dimmer. Incandescent dimmers are based on triacs and a variable oscillator. The LED lamps don't present enough load to operate the dimmer properly.
The LED lights that I added for outside are also a problem. They are attached to motion detectors. The circuitry leaks enough current to maintain a dim glow of the LEDs. When motion is detected, the LEDs illuminate fully. A motion detector style of LED lighting controller should use a relay to fully break the circuit to the LED elements.
