Flexibility is key in designing a lighting concept, according to homeklondike.com.

Though an apparently obvious statement, lighting is extremely important in the home. Not only does it stop us form bumping into things, but it can be used to improve mood and prevent or delay sight deterioration. As such, some thought should go into the lighting of a home.

For rooms where there will be lots of different activity, such as the living room, flexibility is crucial, the website says. It's a good idea to incorporate several different options to cater for all eventualities or use a dimmer switch to create instant atmosphere.

In a space that will be used for entertaining, creating accents of light can create an intimate and welcoming environment; think pretty mosaic lamps dotted on side tables or floor lamps in the corners. For watching TV, light sources should be adequate enough not to cause eye strain. Of course, the situation of plug sockets and the amount of natural light will affect what you can do and how many light bulbs to purchase. 

With most eco-conscious consumers replacing their old incandescent light bulbs with more energy-efficient versions, some may be unaware that the sale of inefficient bulbs has now ceased within the European Union, according to ft.com - positive news, given that lighting assumes 19 per cent of global electricity consumption. China and the USA will follow suit by 2017. 

Sales of LEDs in particular are expected to increase in coming years, as consumers realise they last up to 50 times longer than traditional bulbs and that lighting shouldn't be taken for granted.
