The initial photometric performances of street lighting luminaires are compared using different types of sources and associating the luminous efficiency of the lamp and the useful efficiency of the optics of the luminaire. The analysis shows that the H.P.S. or L.P.S. discharge lamp associated with capable optics can provide useful efficiencies three times higher than luminaires using the H.P.M.V. and F.L. lamp. The photometric performances should be accompanied by good leaktightness performances of the luminaire to ensure the best possible retention over time of the initial photometric performances. Thanks to these performances, a high factor of maintenance can be adopted. A new criterion is then proposed quantifying the maintained performances of a street lighting luminaire. SUMMARY.
