To review a Color Rendering index is a comparison of our light source with an index of the same color temperature. A Correlated Color Temperature (CCT) is described in degrees Kelvin, and it is a comparison of our light source against a standard base line color model that has radiant power at all wavelengths Now we have talked about color temperature and the Color Rendering Index of a light source. In order to get a good picture of what the light source is going to do in our lighting design we need to consider both of them together. For example you can have two or more light sources with the same color temperature and they could be called warm but they render object colors differently. You can have Light sources with the same Color Rendering Index but different Correlated Color Temperatures and they could also render the object color differently. In order to get a more complete picture of how a light source is going to react to a surface you need to use both the Color Rendering Index of the light source and the Color Temperature of the light source together.
When performing lighting design for a room, keep the following facts in mind: Lighting always requires shadow in order to create contrast and visual appeal. Bright overhead lights, while capable of illuminating every aspect of a room, often turn it into a "monotone" and boring space. A given living space typically requires from 5 to 10 light sources in order to be adequately lit. The exact number of light sources will also depend on the color scheme of the room; a darkly painted room will require more lighting than a lightly painted one. Similarly, a heavily decorated room will require more light sources in order to highlight the many interesting features of that space. Matching light collections are ideal for achieving unity in a single room, as well as saving on purchasing time. Pictures and paintings are important features of a room and should be illuminated. Highlighting such items also helps to define the perimeter of a room. To make a room more interesting, try varying the heights of light sources, as well as their intensities (e.g., by installing dimmer switches). Such variations will help create different areas of shade intensity and size.
Rope lights consist of heavy vinyl tubing which houses the string of tiny bulbs. The tubing stands up fairly well to weather, although, rope lights last longer when protected from the elements and used only during milder spring, summer and fall weather. Small hooks can be purchased to screw into material and anchor the rope light strings. The advantage to rope lighting is that it is flexible and can be wound or wrapped around deck and porch railings and strung along eaves. They require regular 120 voltage and can be plugged in wherever there is an exterior GFCI (Ground Fault Circuit Interrupter) outlet. Rope lights can illuminate for years as long as the vinyl tubing jacket is not compromised by severe weather and temperature. The tiny bulbs produce very little heat and the rope lighting can be handled easily, even when lit. Rope lighting can cost from $4.00 to $40.00 depending on the length.
