First row: Quality of light, Phosphors have a narrow frequency range in comparison to a high spectrum incandescent. Adding phosphors to help the light quality adds cost and loss of efficiency. Second row: Size, C F L's are larger than their incandescent counterparts. They may not fit in the existing light fixtures. Third row: Electronics, Using C F L's with a dimmer can short the shelf life. Fourth row: Heat, Higher luminosity C F L's can get warm. They should not be run with the electronics (ballast) above the tube. Therefore, they cannot be used for pendant or recessed lights.
