Well they do but not well and here is why… A warm colour gives a sense of cosyness. During the day this is not important but at night it is a light quality people look for; warm lighting – a warm hue – is used in restaurants, houses, resorts and other places where the goal is to relax. As far as I can tell the warmest white colour from an LED is around 2700K, this is equivalent to about a 100W incandescent or an old bright light. As I mentioned before this colour temperature doesn’t change as the lights dim unlike incandescent or halogen lights which become warmer as they dim. This means that when 2700K LED’s are on full blast they look fine but when they dim the light get gloomier rather than cosier. I know this because the lights are in and its gloomy when dimmed at night. Here is a link to info about colour temperature http://www.seesmartled.com/kb/choosing_color_temperature/
In the double height living area we have two built in lighting effects; a general, central light that operates as task lighting over the seating area and a wall washing effect that lights the side walls to give a greater sense of openess. My plan is to fix theatre gel sheeting to the wall washers in a light amber colour and I have since bought ‘Gel Sheet Orange No. 105’ from Light and Sounds for about AUD$9. Theatre gel is a kind of heat resistant acetate sheeting that is coloured, it is used to create coloured stage effects. I will cut disks from this to go over the light – possibly with a central internal disk cut from the acetate so that some white light gets through.
Hopefully this will mean the walls will be lit by a pale orange light which will reflect back into the room so it feels better in the evening. I will report back on this.
Incidently dimming is complicated, here is a link that explains dimming http://lightproject.com.au/the-basics-dimming
