Choose high voltage for wall lights, deck lights and lights around a swimming pool. You might also want to choose high voltage for a powerful garden up-light to illuminate a large tree or building. With high voltage lights you will need to install an armoured electrical cable that can't be damaged by gardening tools and equipment. You will also need to use appropriately insulated electrical connectors.
Now we can take the color of our light source that we are looking at and compare it with the Color Rendering Index (CRI). The CRI of a light source compares the color of the source to a Black Body color index of the same color temperature. The maximum Color Rendering Index number that is possible is 100. The higher the CRI of your light source the more natural colors will appear when illuminated by it. Light sources with a low CRI will distort the colors that are viewed with them.High (above 80) CRI is preferred in the home. ENERGY STAR requires that qualified fixtures have lamps with CRI above 80. Daylight and all incandescent and halogen light sources have a CRI of 100 and they are excellent at rendering color. For a warm lamp, the CRI is a measure of how close to incandescent color it is, and for a very cool lamp the CRI is how close to daylight it is. The lamps CRI should be listed in the Manufacture's literature.
Battery-powered lights have been the choice of designers, planners and DIY homeowners because these lights provide them with the most flexibility. These lights can be set virtually anywhere due to the fact that they don't require an electricity source. Since these miniature lights don't have power cables as compared to traditional lighting fixtures, the risk of having a fire can be lessened. Recent technological advancements have made these battery operated lights so much better than their predecessors.
