This picture is from Hinkley's site ~ an interesting application shot.
The basics of the "layering" concept are to have more than one source of light. Joe suggests five:
- lighting for grooming
- general lighting
- lighting above showers & tubs
- accent lighting (e.g. artwork)
- decorative lighting
Kichler Lighting has some great tips on their website, too: http://www.kichler.com//consumer/help_page/portlet_help/cms/begin?portlet_helpresource=/OpenCMS/sites/kichler.com/help/Bath_and_Vanity_Lights.html/
Theirs match a lot of what Joe mentioned on the webinar yesterday ~ a vanity light (over the sink & mirror) should be mounted about 80" off the floor. If you are using a pair of sconces, they should be mounted 66" off the floor, and ideally 30-36" apart, if your space allows. You should avoid using recessed lighting exclusively at a vanity ~ it creates terrible shadows under the eyes and chin. I personally love to pair a low-voltage pinhole light over the sink with sconces or a vanity light. The pinhole light will accent the sink and hardware and make them pop, while the vanity light or sconces will light your face.
And don't forget a recessed light in the tub or shower. The technologies have developed nicely in the past few years, and we can now use low-voltage MR16 or line-voltage PAR lamps (both halogen) in wet locations, so again, you can achieve a great pop of bright light in these areas. And don't forget to put all your non-fluorescent lights on a dimmer! Dimmers will save energy and extend the life of your light bulbs tremendously.
