The importance of light colour in energy saving light bulbs and LED bulbs
From the inception of light bulbs in the late 19th century up till the last 2 decades the colour of light developed by light bulbs has always been identical. The eleictrical current flowing through the filament gets it white hot and this results in a yellowish light colour. Now in present time with the current technology in energy saving light bulbs then they can be produced with a whole range of distinctive shades of white ranging from a warm yellowish colour to a cool blue white colour. So life has got more complex again! Previously there was just one option but how there are a wide range of variations to mull over to pick the right one for a living area or a kitchen.
Now with the vast range of Halogen Bulbs, CFL's and LED Bulbs there is the opportunity for choice.
In order to allow you to select the right energy saving light bulbs I will explain in more depth what colour-temperature is and how this technological progression can be exploited.
Detail behind colour temperature for energy saving light bulbs.
The appropriate measure for light colour is colour temperature and the measure used is Kelvin ranging from 2700K to 6400K (Kelvin). The acknowledged way of designating light colour is to use the colour temperature indicator in the range from 2700-6400Kelvin (K). Steel when heated to temperatures between 2700K and 6400K will originally turn yellowish and then through red and white to blue.
The orthodox light bulbs which used a tungsten filament create a warm yellow light at a colour temperature around 2700K.
When the colour temperature is raised to higher than 3000K the glow turns white just like halogen bulbs.
At 3500K colour temperature the glow is now pretty white and corresponds to a general fluorescent strip light or certain CFL energy saving light bulbs and LED bulbs.
At 5500K colour temperature the emitted light has the same colour as bright sunlight.
The top of the spectrum for colour temperature is then 6400K which is similar to the light colour on an overcast day.
There is one facet that is bewildering which is that a allocated cool colour temperature for energy saving light bulbs is at the top end of the range. On the contrary a warm colour temperature of 2700K, which is named warm because of the warm glow, is in all respects at the cold end of the scale.
How to decide what Colour Temperature you need with energy saving light bulbs to meet your needs.
By and large the most appropriate alternative for interior areas like lounges or dining rooms is the 2700k warm colour temperature energy saving light bulbs and LED bulbs . Warm light energy saving light bulbs and LED bulbs are beneficial with subtle skin tones and does not expose blemishes. In addition it highlights the best appearance of fabrics and soft furnishings making it the preferred choice.
Cool energy saving light bulbs and LED bulbs are great for workshops, kitchens and laboratories where the dazzling white light gives very good visual definition.
If your space is multi-function like a kitchen breakfast room then the perfect choice energy saving light bulbs or LED bulbs would be approximately 3500K which provide the best of both worlds.

Light bulbs that have a warm tone like incandescents?
Apparently there's a law that prohibits the sale of incadescent bulbs past the year 2012; I suffer from mild seasonal depression and the CFL and LED bulbs that I've used really don't do it for me, especially in the winter. Are there non incadescent bulbs that have similar, warm tones?
You want CFLs or any other type of bulb with a Kelvin rating of 2700 or so. It will appear, if at all, somewhere on the package or the bulb as 2700k. You might have to hunt for it and they don't all put that on the label. I found it on the bottom of the box in very small print, last time I bought CFLs. Kelvin measures colour temperature, whether a light is warm or cool. The higher the number, the whiter or bluer and cooler a light is. Regular incandescents are around 2700k. The higher k ratings, 5000 and up, approximate sunlight better than the lower numbers. Have you checked into the special lighting for SAD? If yours is mild, it might not take much exposure to the right kind of light to help you.
