Completing a total retrofit of the HPS fixtures with LED fixtures provides a variety of benefits. LED lights are able to produce a wider spectrum of visible light in a more direct and focused manner than traditional HPS. The result is whiter light with less overall light pollution. All in all, LED lighting will illuminate the parking lot more fully than the current HPS fixtures, providing BART parking patrons with an overall better experience parking at the station during evening and night hours.
LED fixtures utilize half as much energy as conventional HPS fixtures. Whereas HPS electricity costs average around $1,900 per month, staff anticipates LED electricity costs of less than half of that figure, $700 per month-saving approximately $15,000 per year. The LED fixtures will save approximately 120,000 kilowatt-hours per year. Additional cost savings will come from the LED fixtures as they have a longer useful life, providing longer maintenance intervals and thus overall lower maintenance costs.
These fixtures also provide options for better control and monitoring capabilities through sensors which can automatically detect occupancy and ambient light levels.
