Electric light
You can never light a room as efficiently as the sun so think of electric light as atmospheric background - it can create a cosy environment or a really dramatic one.
Choose something more versatile than a single bulb hanging from the centre of the ceiling. Use directional lights on a track, which can be used to highlight your favourite painting or mirror.
Layer the lighting throughout the room so you have the right kind for your different needs, such as ceiling lights, table lamps and uplighters.
Put a floor socket in the middle of the room, so you don't have trailing leads across the floor.
Highlight architectural features, such as ceiling coving, with uplighters.
Each lighting type should be controlled separately to prevent the room from looking like Blackpool illuminations.
