A hardy multi-tasker, not only does lighting illuminate, set atmosphere and create ambience, it also performs the role of decoration - whether decorative itself, or highlighting something even more fabulous.
Kitchen Before the dinner party, the kitchen is ablaze with light to make sure everything looks perfect, but once the food is served it is very soothing to leave the kitchen in the dark (where the dishes and the earlier stresses remain perfectly hidden).
However, a few minimal lights, perhaps over the kitchen cupboards, will give a warm glow and relaxed mood - ideal if your home is open plan and the kitchen remains in view.
The same effect can also be achieved at a lower level with floor washers installed into the centre island or in cupboards designed to display beautiful vases and glassware.
Bathroom The bathroom lighting has to work equally hard - in full flood light for applying fake tan but a little subtler for the relaxing soak in the tub.
Bathroom lighting today has made huge leaps of progress, as the industry has not only accommodated the rigorous safety regulations, but has done so with style and cutting-edge design.
Chandeliers, Art Deco wall lights or LED star-lit showers are all now available for the bathroom - just as long as you have a qualified electrician to check the safety zones and of course, install the fixtures professionally.
Bedroom You might well think that bedroom lighting would be less complex but here there is lighting for dressing (to assist in the sock matching battle in the morning) and lighting for reading (so eyes don't strain on one side of the bed but where less literary partners can sleep without disturbance).
A dimmer is an incredibly useful device for most rooms, and they work particularly well in babies' bedrooms where you want to peek in to check on a sleeping child without disturbing them.
They are equally necessary in the living room when the bright lights of late afternoon can be dimmed to a relaxing evening glow.
Architectural Where lights were once the firm domain of the ceiling by way of swinging pendant, they can now be found in most parts of the structure of the house - walls, floors, niches.
Lights set into steps are not only safety conscious, they are also beautifully decorative, and floor washers will give our much-ignored flooring a hint of the spotlight.
For this type of lighting it is worth getting guidance from a lighting expert or a good quality electrician, as the right bulb and the perfectly angled shade will make all the difference.
Fortunately there is a wealth of choice and a style of lighting for everyone - chandelier devotees, retro lighting fans, uber industrial enthusiasts and chintzy tasselled lamp lovers, from Moroccan lanterns that throw colours in every direction to lights that come with a world of button-pushing and timer-setting that will keep the techie you know and love happy forever.
