Over the last few years daylight lighting has become increasingly popular in households and office blocks throughout the country. Why?
What is Daylight lighting?
It is the light that you would see if you looked out of your window at midday if it’s a clear sky. We call this the colour appearance or colour temperature of a lamp and measure it in degrees Kelvin. A daylight bulb will have a colour temperature of 6500 degrees Kelvin or 6500K.
Daylight lighting V normal lighting
Normal household bulbs when lit have a yellow or warm white appearance that is equal to 2700K. When we light offices we use 4000K that has a more blue or cool white appearance than household bulbs but not as cool in appearance as daylight bulbs. But this is now all changing
Daylight bulbs had always been available from lamp manufacturers but were restricted to use in special applications such as illumination of fish tanks and exotic reptiles, colour matching of fabrics and daylight simulation.
A cure for SAD?
In the early 1990’s David Davies from Beaconsfield, Buckinghamshire formed a company called Full Spectrum Lighting that introduced a range of lamps from the United States that were daylight balanced and promoted well being and a solution to Seasonally Affected Disorder (SAD). Seasonally affected disorder is a feeling of low well being or depression caused by the depletion of natural sunlight, and is most prevalent in winter time. Due to the popularity that this created for daylight bulbs more lamp manufacturers added daylight bulbs to their product range. So we now have daylight bulbs in energy saving compact fluorescent types, fluorescent tubes, as well as some regular household bulbs.
Daylight bulbs have now become very popular because they can bring the light that we would experience when we are enjoying a walk in the park on a bright sunny day into the home or place of work, creating a better environment under artificial light.
