subject: The Science Of Balanced Lighting [print this page] Balancing light within a room or space not only provides a more aesthetically pleasing atmosphere, but can also allow for better moods. However, there is more to creating this balance than simply installing a light here and placing a lamp there. A simple way exists for the layman to scientifically create a near perfect balance of lighting in any area of the home or office.
First of all, there are three types of lighting which need to be considered. Task lighting is a direct source of light that is used for properly illuminating a specific task, such as reading or working. Accent lighting is a light source which illuminates a specific area other than a specific task. An accent light can be used to highlight a bookcase, corner of a room, entranceway, etc. Then there is ambient lighting which is the light source which brightens the spaces in between task and accent lighting. Ambient light is often diffused by being radiated off of walls or ceilings into the rest of the area.
The science of balanced lighting requires that these lighting sources be mixed and matched in order to provide the correct fusion of light throughout the entire space. In order to achieve this, the focus needs to be on the correct ratio of ambient light which lies between your task and accent lighting sources. The ideal ratio of task/accent light to ambient light is 3:1 or 4:1. This simply translates into the task and accent light being three or four times brighter than the ambient light.
In order to establish these correct balances of light, a light meter is used. However, before running out and buying one, check your digital camera because most digital cameras today contain a built-in meter.
The trick is to delicately balance your light sources in order to attain this task/accent light to ambient light ration throughout the entire room. Using your light meter, walk around the room and take readings. Wherever the area is too bright, try moving task or accent light sources away from the area. Wherever the area is too dark, simply move these sources closer together, or add a light source such as a wall sconce or a Torchiere lamp. Continue this process until the correct ratio is achieved throughout the room.
Existing light fixtures can often be adjusted in order to achieve a proper balance of light. Fixtures such as track and spot lights can be moved and/or swiveled to direct light into or away from problem areas. Many recessed puck lights also rotate for the same affect.
Once you create the proper balance of light within your home or office, kick back and enjoy the benefits of a happier atmosphere!
