Title Outdoor Areas Lighting with LEDs – the Competition Between Scotopic Efficacy and Light Pollution Type Journal Article

Abstract In this paper the effect of spectral power distribution SPD

of typical outdoor LED lamps on star visibility index SVI was analyzed.

For those lamps the nearest color temperature CCT [K] and scotopic

efficacy lm/W] data are also provided. The SVI has been defined as a

ratio of its scotopic flux to scotopic flux created by full moon light. The

calculations show that there is a strong relation between CCT of LEDs

and SVI index. Low CCT of the lamps does not significantly affect their

SVI value. Unfortunately, those kind of lamps are less attractive in

applications because of their low .
