NEED-LESS LIGHT POLLUTION SIMULATOR


Good outdoor lighting practice is easy to achieve if some simple rules are followed. The key point to remember is that we should only light the area that needs illumination. Maximum efficiency can be obtained by using the minimum amount of light required to see the illuminated surface, in this case, an empty parking lot. Any light which falls outside this area should be minimised, since misdirected light represents wasted energy and poor lighting practice. Misdirected light also causes light pollution problems such as light trespass on nearby property, excessive glare and increased skyglow. These problems may easily be avoided by choosing the correct type of light fixture. There are many designs of light fixtures to choose from, some designs are decorative whilst others offer more control over the distribution of light. The best fixtures to use have 'full cut-off' optics that are specially designed to reflect any potentially wasted light back downwards, where it is needed. These lights, if installed correctly, may produce more useful light than other designs whilst consuming less energy!

Please choose the window size to suit your monitor, a smaller window will run faster on a slower machine.
