Light quality and colour can dramatically change the appearance of a room so it is important to get this right. You wouldn't, for example, want bright white lighting in a bedroom, instead a soft warm white ambiance would be more suitable. When choosing a light bulb you first need to decide which colour temperature you require. Colour temperature is a measure of how warm or cool a colour appears. It is measured in Kelvin; the standard measurement for lighting output in addition to lumen output. Colour temperature is derived from the colour of light produced when carbon is heated. The Kelvin Scale ranges from extra warm white at 2,700k giving a warm yellow glow, to white at 3,500k, cool white at 4,000k and daylight colour at 6,500k which produces a white blue colour. LED, CFL and halogen energy savers are all available in a range of colour. Complaints have been made in the past about LED giving off a cool blue light but with the improvement in technology, as long as you buy a good quality LED this should not be a problem. It is then important to look at the colour rendering index (CRI) which shows to what extent the light will make an object appear its true colour. An incandescent bulb is rated at 100% because its light contains a full spectrum of colour. CFLs do not contain the full colour spectrum but a good quality triphosphor fluorescent rated between 80-90% will be sufficient for everyday use. Higher rated CFLs can be obtained but are usually only used by designers or artists and are less efficient. It is advisable not to buy a light bulb which scores below 80% on the CRI scale. Energy saving light bulbs have received a bad press at times because of the light they produce, but this has tended to be because many poor grade CFLs either brought from supermarkets or given out for free by energy companies have come onto the market.
If you decide to install high voltage lighting I recommend that you consult an electrician for advice. Get him or her to carry out the basic cabling and installation work. If you choose a low voltage system (by far the most popular) you can much more easily install it yourself providing you follow some basic safety guidelines. The specification for the cables is still important, but you don't need to bury them deep underground as you would for a high voltage system. However, bear in mind that the cables are still capable of giving electric shocks if damaged. Most garden centers have a wide assortment of low voltage systems and fittings that are suitable for outdoor use. If you buy a low voltage kit it will come with a transformer as well as cabling and fittings. Make sure that you position the transformer in a dry place indoors or in a garageoutbuilding.
Room lighting must capture and enhance the character of the person who lives in the room, as well as provide proper illumination for everyday needs. That's why you'd better think twice about mission of each room of your house and how natural light can outline it. Also take into account that the daylight changes throughout the year. How to maximize natural light? There are several ways to do it: Mirrors can reflect and multiply the natural light - try to hang them in front of your windows. Ooften there can be too much sunlight in your room - use voile or muslin to defuse it. Hot sunlight can be stopped by perforated roller blind. Your windows are small and you don't get enough sunlight? Your inner door can serve as a window - think of a glass paneled door. Don't have place where to hang an extra mirror? Any surface of your furniture can reflect sunlight. Just make the right choice. What is outside your house? Maybe it's a big old tree that blocks all the natural lights? You can always try to trim it.
