LEDs have advanced a lot in the last decade. In addition to the normal on/off, there are three-way LEDs and dimmable versions - though the lower power dimmables may need a dimmer specifically built for the very low power of LEDs.

2700k is a yellowish light that corresponds to a standard incandescent, or maybe a bit yellower. 5000k is a bright white light, and 6500k has a spectrum like sunlight - which is harsh for lighting at night, but good for lighting in an area where you want to see the actual color of an object.
Lower k-values than 2000 are generally comparable to candle-light.
Many stores like Home Depot have displays showing the color differences so that you can actually see them yourself before buying.
We have some LED E12-size lamps in the candelabra that are very nice and dimmable from a fair white to a golden glow.
Thank you for the ideas.
