If I were to criticise its just that it does change the colour of the tile and makes it look more yellow rather than white but apparently the warm is more 'homely' and less 'clinical' or so I was told in my consultation.
J, warm white is 3000kelvin (k) but you can also get natural white (4000k) which is not too yellow and not too white (like CFL)
