The Lighting Objective
A well lit room is one in which all the the lighting design (both fixtures and technical plan) blend together to create a beautiful environment in which your eyes focus on the objects the light falls upon rather than on the light itself.
Guide Purpose: This guide is a practical overview of lighting technology and application. Our focus is to teach people how to create a better lighting environment while achieving high levels of energy conservation.
Types of Lighting
This light is mainly used to illuminate an area where activities like reading,sewing, or preparing food occurs. Task lighting is often achieved with fixtures that direct light onto a work surface.
Most often called the "general light" provides a soft level of light for watching TV or entertaining.
Similar to task lighting, however the light is focused directionally. Used for artwork, architectural features, or reading.
When you need a lot of light, utility lighting is used mainly for "flood areas" such as outdoors or when doing work around the home.
Light bulbs emit billions of little light particles from their surface. The amount of light particles emitted is called Lumens. If you look on a light bulb or on its package you will see how many lumens it emits; the higher the lumens the better we should see (keeping color constant: see Color).
Depending on what type of activity you would like to perform there are recommended lighting levels. Because light levels change with the distance from its source and items like shades and covers block light, one can measure the light level using a light meter (costing approx. $30) which will read the light in lux (i.e. lumens per square meter). We have provided a short guide to help you determine the appropriate amount of light for various activities.
Intensive reading or studying
Kitchen & laundry
Model building or hobbies that require detail
Color of Light
A light's color affects how we perceive the color of an object. For example, a blue painting under a bluish light will heighten our feeling of its blueness but a red painting under a blue light will make it very dull and grayish because there are no "red color waves" made by the light.
The main indicator of color is the CCT (correlated color temperature) measured in degrees Kelvin. Lights of America typically uses 2700K warm spectrum bulbs for indoors and 6500K for outdoors
Light sources also have another important index: The color rendering index (CRI) scaled 1 to 100. CRI is important in a home because it affects how furniture, decorations and even people look. Incandescents are considered the best at 95 to 100. Newer Tri-Phosphor Fluorescent (this is all Lights of America uses 84 to 88
CRI) is rated above 80, while mercury vapor and old fluorescent are 62 or above. Using CRI with 84 or better gives very little color shift loss.
