Lighting. Monday , September 17th , 2018 - 17:35:58 PM
Indoor lighting is usually taking the place of natural light, or enhancing it. Various rooms in the house or office many already receive natural illumination during the day but need additional help, and of course, at night the lighting needs to be fairly bright. There are so many products on the market. You can choose ceiling, wall or track lighting, recessed lighting and many more options. The key to choosing the right balance is to consider what the rooms will be used for, and when, and what energy efficiency ratings you are ideally looking for. Indoor lighting can come with many features such as dimmer switches.
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.
Lighting can take many forms in the garden and can be tailored to suit numerous different types of applications. For example, a water feature that would otherwise be invisible to the eye after dark can be transformed by a single underwater spot light, creating an elegant feature that makes a statement at night. Bollards and floor-mounted lights can lead your way along a path at night as well as provide a warm and inviting look for the garden in the evening. Spot lights can light up tree canopies and artwork in the garden. In the case of statues, display pots and other artwork it is preferable to use a spot light from the left and the right side in order to add depth to the piece - a single spot light in the front or from one side tends to create a comparatively 'flat' or two-dimensional look.
