There is no ‘one size fits all’ solution to kitchen lighting because kitchens take many forms: from the narrowest galley kitchen to large open plan rooms incorporating spaces for dining or socialising.
There are, however, a number of general points to consider and Unit 6 of Lighting 101 looks at these.
The starting point for lighting a kitchen is task lighting. Food preparation involves a number of tasks including: reading, washing, weighing, peeling, chopping, cooking, cleaning, etc. Poor lighting stops these tasks being safe or enjoyable and it is necessary to ensure good light levels in the areas these activities take place.
There are several options for task lighting. For completely new kitchens, recessed ceiling lights are a good solution. When planning this type of lighting, there needs to be enough sufficiently bright fittings to ensure a good light level on work surfaces. If the recessed lights are adjustable, the light can be directed. And if they are dimmable or rows can be switched on and off independently, this can help meet other lighting requirements for the space.
Potential problems in relation to shadow need to be considered, particularly if there are cupboards above the work surfaces. The effect of the cupboards and a person standing at the work surface is to create a narrow channel down from the ceiling below where the lights need to be positioned to prevent shadow. Under-cupboard lighting can solve this problem. Cooker hoods generally have built in lights to ensure good lighting on hobs.
For existing spaces where retro-fitting recessed lights might be problematic, wall and ceiling mounted light fittings – fixed or adjustable – may be simpler to install. There are fittings which have a number of independently positionable spotlights on the same fitting and these can be an effective substitute for recessed lighting.
For general lighting, there may be sufficient natural light from windows during the day and the task lighting may provide sufficient light through the rest of the room at night. Natural light is maximised by reducing obstructions to the path of the light and having pale surfaces or finishes to reflect as much of the light as possible.
A key consideration is the location of cupboards and islands which might mean ceiling lighting is insufficient to illuminate the insides of cupboards. While some appliances will have built-in lighting (fridges, freezers, ovens, etc) others won’t. Rummaging in a dark dishwasher or cupboard is never a happy experience. Lighting on the plinth or kick board of floor cupboards can be an effective way of increasing general lighting near to floor level.
From a technical perspective, the colour temperature of kitchen lighting is important. While warm white (between 2,500 and 3,000K) might generally be suitable for lighting in the home, a cooler temperature may be more suitable for task and general lighting in kitchens. Too warm a colour temperature can make pale or white surfaces/finishes look dirty. Conversely, very cold white light can be uninviting and cause wood to lose its natural ‘warmth’.
Effect lighting is lighting which provides visual interest – either the lighting fitting itself or the light produced. There are a huge range of kitchen styles. Whichever style you choose – farmhouse, rustic, modern, minimalist, Mediterranean, etc – or however you choose to describe your kitchen, the light fittings need to fit in with the overall scheme.
Given the practical use of the kitchen, it is unlikely you’ll want to create visual patterns using light, so the essence of effect lighting in the kitchen is the contribution made by the light fittings to the overall design. Although there are a huge choice of light fittings, it is important to remember that cooking inevitably produces airborne particles of smoke and grease. While it is important to consider the visual effect of light fittings the kitchen, it’s also important to consider how easy to clean they are. Glass, ceramics and metallics may be preferable to fabrics or organic materials.
The final consideration in lighting the kitchen is whether ambient lighting will be required for when the kitchen or other areas of the room are used for relaxing and socialising. The right ambience could be created by using reducing the number of light fittings which are switch on or dimming. For lighting over tables, pendant hung low and with a dimmed warm white light source can be particularly effective.
