visibility and are unable to serve the purpose. Therefore, it is important todesign outdoor lightingsuch that it provides required Illumination levelsduring night.

Usually people relate quantity of light to safety; however, it is not the

uantity but the uality of

light that gives rise to the feeling ofsafety and security! In fact, excessive illumination or light thatIs notfocused properly causes glare or highbrightness contrast, which results inloss of visibility.

!revalent notion of "the brighter the better" and general insensitivity of

people towards energywastage often results in high energyconsuming outdoor lighting schemeswith illumination levelsthat are much higher than what is necessary. Poormaintenance and operation are other ma#orfactors contributingto$ards energy ine%ciency in outdoor lighting. #utdoor light switchedonduring daytime is a common sighting in urban areas.
