2. The Aging Eye and the Danger of Facial Recognition Failure The average age in our community ranges from 73 to 76. Physiological studies show that older adults require significantly higher vertical contrast to distinguish moving objects and recognize faces at night. lf we transition to fully shielded fixtures, at our current lamppost heights, we are drastically dropping the vertical foot-candles (the light that hits a standing body). This creates a dangerous optical environment for seniors: e Inter-visibility Failure: a driver turning a tight corner will not be able to see the upper body of a resident in time to brake. e Security & Anxiety: Residents walking at dusk will no longer be able to recognize the faces of oncoming people, significantly decreasing the actual and perceived security of our private roads. Our current system strikes the perfect balance: our solid top prevents light pollution into the night sky, while our translucent light fixture panels provide the vital horizontal throw needed to keep human bodies illuminated and visible. 3. The Legal Liability of Changing a Proven System From a legal and liability exposure perspective, changing our infrastructure poses a major risk to the Condominium for three reasons: e No History of Negligence: Our current lighting system works well within our local laws (producing no more than 1.23 foot-candles at 10 feet, safely below the municipal 2.0 foot-candle nuisance threshold). In the history of our Condominium, we have had zero lighting-related accidents. e Creating a Known Hazard: If the Condominium modifies these lights to a fully shielded design, and a resident is subsequently struck by a vehicle because their upper body was hidden in a shielding shadow, the Board/Condominium can be sued for creating a known visual hazard.
