HOW WELL CAN YOU RECOGNISE OBJECTS AT NIGHT? Not very well if the luminaires are extremely bright compared to the objects around them. The pictures below demonstrate this phenomenon. Notice the difference in the "visibility" or clarity of nearby objects illuminated by a Promenade luminaire. Disability glare or "veiling luminance" (the contrast ratio between the brightness of the luminaire and surrounding objects) is greatly reduced. Visual perception is greatly improved with the Promenade Series.
