I built a house a couple years ago where the lighting used is predominately LED bulbs and I absolutely hate it. The pre-determined lighting plan for the home was presumably based on the brightness given off by certain incandescent bulbs and placing LED bulbs in those locations that are supposed to be wattage equivalent has resulted in a fairly dark house with what I would consider to be low quality of light. Many of the bulbs used in certain fixtures also emit a noticeable high pitched noise when on.
