Take some time to consider the mood and the function of the room you are lighting. For example, a bedroom may need only assorted table lamps to feel and function properly, while a kitchen demands task lighting for performing specific chores.
Scale is very important when selecting lighting fixtures for two important reasons: dimension and light output.
The physical size of the lighting fixture selected is important in relation to ceiling height and the overall size of the room. For example, a small three light pendant in a high ceiling grand Victorian room will look just as inappropriate as a larger five light in a lower ceiling bungalow.
While there is no hard and fast rule, consideration should be given to the light level you require and the function of the room. As a broad guideline for general living areas, the following formula can be used to determine your choice of fitting.
| | Number of arms (on light fitting) = 20 x area in square metres divided by the wattage of the bulbs per arm. For example a 15 square metre room could use a 3 x 100w fitting or a 5 x 60w fitting. |
| | If you have the fixture you require and want a guide to the area it will cover use the following formula: Area = number of arms x lamp wattage divided by 20. |
It must be stressed that this can be used only as a general guide and there is room for flexibility. Keep also in mind the room’s lighting can always be complemented with wall or table lamps. Approximately double the above requirements are suggested in work areas like kitchens, studies, sewing rooms and bathrooms. For study and fine work an individual table lamp should be used.
