Home is always a top priority and reflects a person’s personality. So we are very concerned about the area, so we should take atmost importance to see that well organized and well lit. If your lighting is not adequate then how ever you stay neat and the best purchases of furniture, your house will look dull and bland. Have seen that when it comes to decorating a new house or improvements that top priority always goes to furniture’s, curtains, sofa sets, pictures and other decorated items as well as lighting to take last priority. But should any other way, because lighting will make or reduce the beauty of your home. You tend to use your funds to other items and when the lighting comes you have less funds and you tend to compromise with it. But you must understand that it is the lighting that will brighten your home and add color to your house and your interior decor. It is unfortunate that the lighting is always neglected. To understand lighting you must understand some definitions like lux, color rendering, flux, energy efficiency, and efficacy. Flux: Flux means the light output given by the bare lamp. And units of Lumens. Lux: Lux can be defined as the light output or flux in a particular direction per unit area. Lux is a candlepower. Color rendering: Color rendering can be defined as your color compared with natural colors of sunlight. Under bright sunlight you get the perfect color. Energy Efficiency: energy now one of the most important day, the energy saved is energy produced. Thus, energy efficiency can be defined as with less energy being used or you get your watt maximum light output. That’s why you see (CFL’s Compact fluorescent lamps) T5 lamps on the market. Because the most talked about is energy efficiency. Day by day the cost of electricity increases and the energy saving is very important for all and every state. Let us study the case of your guest room. The living room is a place where guests come first, or where you sit with your children and other family members and watch your favorite TV Soap. So, you should understand the importance in your life. So you must be careful in placing the lightest. Your room lights should be seen not only in the corner of science, but also at the corner of artists. Why do I say this because if you only see in the corner of science, you put the formula for designing the lighting then you get the amount of light required, but your room is a place of importance, so also look in the eyes of an artist. Lights will differ according to mood. You might not always required bright light, but some times you may just need a spot light or reading light near your sofa. What I want to say is that lighting should not be viewed as a formula for putting and getting results? Lighting is different in different times and different moods. In drawing room one should use diffused lighting, some indirect lighting, some spot lighting with CFL or Miniature Halogen (MR16) or a mixture of both. Some table lamps for studying purpose and some general lighting. for all purposes. diffused lighting will not provide eye glare and smooth touch. This is used for general purposes. But you must be a party at home or you’ve got a special guest in addition to general lighting so you can also spot you turn on the lights or high lighters to high light some decorative pictures or statues. Put the lighters immediately, until the mild to high your ceiling and get indirect lighting. Suppose you have a dinner or cocktail party then the mood is different, that time you can put indirect lighting one or two spot lights to give a party or a relaxing atmosphere or ambience. Suppose you are in a romantic mood, and sitting with your wife you can create a romantic atmosphere by wearing jummes and one or two indirect lighting only to create a romantic atmosphere. You are not in a good mood you can use indirect lighters only. Or you want to learn then you can only have turned on the light table to learn. See why I say that lighting should not be seen only point of science, because lighting will change according to your needs or moods. Lights can not be longer this will interfere with or give glare if lighting is not adequate it will create a dull effect. Lighting also will differ in different places to provide a different atmosphere. To give the effect of warmth or welcome you can get the warm light of day. Like 2700 k (Kelvin) lamps, to give a cool effect or give assurance you can have a day of light 6500k (Kelvin) lamps cool. See the Light is a major subject of his own. LIGHT SHOULD NOT be taken lightly.
