Convenience Store Owners Find Payoff in LED Lights

Everyone knows the places well. They are the comforting light that is barely visible along the long, dark and lonely highway. Quick shop, neighborhood grocery or convenience store, whatever the name, we all know what they mean. Whether it’s candy bars, cigarettes, or a tank of gas and a good cup of joe, the good old quickie mart is there to grant your every wish—24 hours a day, 7 days a week, holidays and hurricanes too.

Canopy lights are just one area where LEDs can help convenience stores, gas stations and all-night stores save money. Some owners have seen savings as high as 70 per cent compared to non-LED lights. Payback on the investment in LEDs can be as little as a couple of years.

Part Two: Daylight Harvesting, Other Dimming Strategies Help Lower Energy Costs

Daylight is free, and many spaces inside buildings are daylit, yet electric lighting is left on unnecessarily. Daylight harvesting harnesses this free, natural light, using such building control system strategies as light sensing, occupancy sensing, and shade control, while automatically adjusting the energy use of HVAC and electric lighting systems.

The results? Reduced overall energy costs, coupled with healthy and productive working environments. Daylight harvesting technologies include photocells, occupancy sensors and centralized or distributed control systems. The strategy can be implemented during building design and planning or even retrofitted flexibly at a later time. Continue reading

Dubai To Convert All Lighting To LED

Dubai Municipality, one of the main administrative departments of the Emirate of Dubai government, has signed a memorandum of understanding (MOU) with Philips to convert all of the municipality’s lighting to LED. The agreement embraces all 262 of the municipality’s buildings, including city government offices, schools, public buildings such as courts and sports venues, and transportation buildings. The transformation from conventional lighting to LED is expected to save the Municipality up to 50 percent, roughly 10.5 GWh per year, on its energy consumption. It will also mean a reduction of some 6,200 tons of CO2 emissions per year.

LED Lights Cut Crime in Baltimore Parking Lot

Johns Hopkins School of Medicine is located in historic downtown Baltimore, Maryland, and is one of the most prestigious learning institutions in the country, but it is also in the midst of a crime wave that disturbs citizens and authorities alike. Since July of this year, there have been several incidents involving attacks and robberies near campus on employees traveling to and from transportation and parking lots. Several of these crimes involved the theft of cell phones that were grabbed from unsuspecting citizens. Police and campus authorities are recommending that pedestrians in the area remain aware of their surroundings at all times and not advertise that they have a cell phone in their possession in an effort to deter the criminals. The single most important tip they have for individuals is to stay in well-lit areas after dark. It is well known that adequate lighting is a major crime deterrent, so avoid dark places and isolated, shadowy areas.

Since manager installed lower-wattage, brighter burning LED lights in a parking lot near Johns Hopkins Hospital in Baltimore, residents report that crime in the lot (not shown), mostly theft, has dropped significantly.
