On a separate note Steve, how have your 5000K lights been received? Some people have a strong preference for very yellow warm white (2700k) and feel 5000K is too "hospital like".
Myself I am down with 5000K. i put 4000K in my kitchen and that seems a good compromise. I am using 3000K in my livingroom. I find the difference between 2700K (warm white) and 3000K (cool white) very noticeable and much to my liking.
