Remember that a full moon can make an area seem quite bright. Brighter is not always better, so try to choose lights that will meet your needs without illuminating the neighborhood. If you can't decide what to do, consulting a good lighting designer is usually your best bet. Such fixtures have minimum glare from the light-producing source. Fully-shielded light fixtures are more effective and actually increase safety, since they have very little glare.
Glare can dazzle and considerably reduce the effectiveness of the emitted light.
It has the lighting fixtures carefully installed to maximize their effectiveness on the targeted property and minimize their adverse impact beyond the property borders. Positioning of fixtures is very important. Even well-shielded fixtures placed on tall poles at a property boundary can cast a lot of light onto neighboring properties. Fixtures should be positioned to give adequate uniformity of the illuminated area. This can create a safety problem.
