the nearest security camera to where motion is detected

GE's considerable portfolio of exterior lighting products includes many aesthetically attractive fixtures offering long life, durable construction and an assortment of beam spreads to suit a wide variety of applications," notes Steve Briggs, vice president of product management and marketing for GE Lighting Solutions. "Our LED area lights consume between 97 and 220 watts and were designed to replace traditional 400- to 1,000-watt high-intensity discharge (HID) systems that can spill and waste light."

Marriott also gained the functionality to dim its new garage lighting with GE's ProSys™ Lighting Control system incorporating motion sensors. Light output is reduced to 40 percent while the garage is vacant and adjusts to 100 percent when motion is detected. Alone, this precise control will produce nearly $11,000 in energy savings (88,000-kWh reduction) each year. And, the control system will interface with Marriott's video surveillance center, alerting guards to after-hours movement in the deck and focusing the nearest security camera to where motion is detected.

Marriott also coordinated with Montgomery County government officials to replace 32 180-watt metal halide streetlights along the road that serves its headquarters and neighboring companies. With the first cost of GE's 106-watt Evolve LED Roadway Cobrahead fixtures covered by Marriott, the county will see an immediate benefit: using 10,000 fewer kWhs each year provides a $1,200 annual energy savings.

In the foyer, special scaffolding is needed to reach fixtures in the high ceiling. Marriott would change the lights, which lasted just one to two years on average, only once a year at a cost close to $3,000. Maintenance savings will now add up after GE replaced 12 90-watt bulbs with 20-watt LED PAR38 lamps. Rated for 50,000 hours of life, GE's LEDs could keep the scaffolding away for up to seven years.
