Introduction There are numerous researches that focus on effects of lighting (luminance and spectra distribution ) on man . They generally show an impact on light estimation, cognitive performance, mood and behaviours ( Veitch, 1997, Knez and Kers, 2000, Knez,2001;Hygge and Knez, 2001,), but this type of research is generally conducted in indoor artificial lighting. Very few focus on outdoor night lighting except Hanyu (1997) who sought to examine relationship between two sets of variables :visual properties and affective appraisals in night time neighbourhood experience. This research was not a field study because participants have, in an experimental procedure, only to rate different slides of night time scenes. Main PurposesOur main purpose was to examine, in a field exploratory study, how people evaluate the outdoor night lighting We sought to find out people’s expectations of the various functions of urban lighting, to know what criteria they use to evaluate a good lighting ( between physical, affective or cognitive ones) and to know what improvements they suggest. In this study , we expected the issue of personal security to be an important factor (in regards to lighting) and that individuals and contextual factors as age, gender, length of time spent living in a given area and localization would influence the evaluation of the functionality and quality of lightingMaterial and Methods A standardized questionnaire was established from a set of non directive interviews and submitted to 140 persons representative of the eighteenth district of Paris in regards to age, gender and socio-economic background . This research has been conducted in two areas in a similar neighbourhood in regards to age, gender, and socio-economic background.ResultsThe mains expectations towards the lighting functions where: in first to walk easier(92%), to valorise the city (91%°), to make an area more attractive (90%),to find one’s way(88%) to increase security (85%)to take advantage of the city (85%), to make the area friendly (82%), to generate activity (76-%)…A good lighting needs to not dazzle (96%,), with an sufficient intensity (95%)with pleasant colour (88%),adapted to the type of area(82%), to the length of street,(80%),with various sources of lighting(80%). It should not create shadowed areas (69%) and to be adapted to size of the population (46%). Between the different sources of light the most important are street lamps (98%), the lighting of monuments (80%) , wall lamp (77%),the light from restaurants or coffees shops,(73%), from shop window(53%), from cars(30%), from windows(28%°)We also found that the satisfaction in the neighbourhood is linked to the evaluation of the lighting (X2=85 ,p<.001 people="" who="" are="" more="" satisfied="" with="" their="" neighbourhood="" also="" the="" quality="" of="" lighting.="" satisfaction="" has="" an="" impact="" on="" different="" expectations="" toward="" urban="" lighting="" and="" proposal="" for="" improvement.="" age="" influence="" to="" improve="" security="" or="" create="" activity="" importance="" type="" .="" over="" fifty="" years="" propose="" increase="" p="" gender="" a="" given="" subject="" mediates="" evaluation="" interesting="" finding="" is="" that="" women="" men="" do="" not="" like="" same="" colour="" prefer="" colour.="" blue.="" localization="" inhabitants="" area="" in="" linked="" functions="" such="" as="" valorise="" city="" take="" advantage="" make="" attractive="" friendly.="" number="" have="" been="" living="" mediate="" global="" function="" good="" proposals="" improvement.conclusionsecurity="" first="" expectation="" dwellers="" regards="" main="" interest="" be="" able="" walk="" safely="" followed="" by="" expressed="" concern="" valorization="" itself="" .a="" too="" strong="" but="" adapted="" street="" spaces="" density.="" sex="" length="" time="" evaluations="" night="">
