” color of the light is very good, just like an incandescent.”

LEDs produce light at discrete frequencies. A white bulb has a red, green and blue LED that is white-looking.

But incandescents produce a continuous spectrum of light that I agree is more pleasing.

But in the LED flat screen TVs, each pixel has a red, green and blue LED and these TVs produce pictures that no one criticizes for their absence of richness of color.

So I don’t know what to conclude in comparing incandescents with LEDs.

Some LEDs use an RGB system but most use a phosphor that emits over a broad color spectrum. The typical white LED bulbs you find at the store are the phosphor type, not the RGB type.

My ceiling recessed LED fixtures (or replacement bulbs in regular recessed cans) all have adjustable light temperature. There are five settings from very cool to very warm. I generally choose on the warm side to match the incandescents I’ve replaced.
