LEDs produce light by the process of Electroluminescence. This is the phenomenon where by light is emitted from a material when an electrical current is passed through it. An LED chip is made from a material doped with 'impurities' to create a p-n junction between two types of semiconductors and electron holes. Electrons can only flow one way across the junction and as they do they fill electron holes causing their energy level drops and the release of photons (light).
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.
Solar lights come in a variety of styles: two or three tiered lamps, lanterns that hang from an ornamental rod, bollards (small, dome-shaped lights,) tiki torches, fence lights, post lights, small reflector-type flood lights and walk lights with star-patterned down lights. The average cost of a solar light can range from $2.50 to $5.00 depending on the size and whether it is metal or plastic. Most solar lights are LED's today and give a crisp white light that lasts longer than an ordinary incandescent bulb. Solar lights can last for two, three and sometimes four years-the rechargeable battery can easily be replaced when the light grows dim. Solar light provides an attractive accent light that can be used in any area of a yard or garden. Place them where they can be exposed to sunlight all day to get the best and longest illumination at night (usually eight to ten hours.) Solar lights can be purchased singly or in packs of six and ten.
