Elevator lighting gets an upgrade with LEDs

Upgrading Incandescent Elevator Downlights to LEDs Yields 45% Energy Savings

Lighting Research Center conducted a recent field study called LED Low-Profile Fixtures. In the study, researchers from the Lighting Research Center modified the elevator ceiling panel replacing the original incandescent fixtures with six prototype fixtures with each fixture having six 3-watt high power white LEDs and a custom-designed reflector.  The LED downlights were recessed into the ceiling and shortened the required space clearance required by 2 inches. Although the illuminance levels in the elevator cabin were similar between each type, the LED fixtures clearly demonstrated an energy savings of 45%. A total of only 165 watts of electricity was required by the six LED downlights while the original incandescent downlights required 300 watts.

The six LED downlights required a total of 165 watts of electricity, compared with 300 watts for the original incandescent downlights, for an energy savings of 45 percent. The illuminance levels inside the elevator cabin were similar between each type of downlight.

Additionally, the LED fixtures have an expected lifespan of 40,000 hours or over 4 years of being used all day long every single day. The incandescent fixtures traditionally used in elevator cabins on the other hand only operate between 1,500 and 2,500 hours. On top of having a longer operating life, LEDs’ nature of a gradual decrease in light output instead of outright failure to produce light, allows maintenance crew to plan for relamping instead of responding to lamp failures as they happen. LED therefore can also cut down replacement and maintenance costs.

According to the survey conducted, elevator passengers found the LED-modified elevators better in terms of visibility, comfort, color and attractiveness of the light compared to the original incandescent fixtures.

The study revealed that LED downlight fixtures can give the elevator industry more than just energy savings from lighting. Because of the low-profile design of the LED fixture, elevator manufacturers can design elevator cabins shorter than the original height required when using traditional incandescent and fluorescent fixtures by as much as 4-6 inches. Shortening the height of the elevator translates to less materials needed for building the cabin and a reduction of the cabin’s total weight. The reduced weight means smaller motor and braking systems can be put in place.

California Energy Commission’s Public Interest Energy Research Program with the Architectural Energy Corporation were the major sponsors of the study.

GNC stores upgraded with Lighting Science Group’s LED lamps

GNC Stores Go Green with High Performance LED Lamps Resulting to 80% More Efficiency

With lighting accounting for 22% of energy use in the United States and with commercial buildings using up to 60% of the power, General Nutrition Centers, a retailer of health and wellness products based in  Pittsburgh, PA, recently upgraded to LED lighting to cut energy use and costs.

Corporate stores of General Nutrition Centers (GNC) across the US and Canada underwent a lighting makeover with LED lamps replacing old halogen bulbs. North America’s largest retailer of health and wellness products opted to have high-performance LED lamps in their stores for better efficiency and greater light output. The LEDs illuminating GNC’s retail display shelves are 80% more efficient than the old halogen bulbs, are fully dimmable, and have up to 50% greater light output.

With the lamps expected to last for 50,000 hours and lower maintenance cost and lower cooling costs compared to the halogen bulbs, GNC expects that their lighting upgrade will pay off in just 1-2 years.

Tom Dowd, GNC’s executive vice president and general manager said that their decision to upgrade to LED lighting is in line with the company’s values. He added that LED lighting is not only easier on the wallet and better for the planet, it is also beneficial to one’s well-being. The largest retailer of health and wellness products across North America believes that LED is ahead of incandescent, halogen, and fluorescent fixtures when it comes to considering lighting features that may have an effect on one’s general health such as flicker, hum, burnout, heat, and toxic materials.

Lighting Up Georgia Convenience Stores

Convenience Stores in Georgia are Saving Energy After Upgrading to Energy Efficient Lighting

In Georgia, convenience stores are cutting their energy usage and costs thanks to energy efficient lighting upgrades made possible by the Recovery Act funds from the State Energy Program and the Georgia Environmental Finance Authority. Implementation of lighting efficiency improvements was then carried out by the Georgia Association of Convenience Stores to participating stores all across the state. Just after a year of the upgrade resulted in savings of $7,000 in energy costs and 54,000 KWh in energy consumption for the first participating convenience store.

Over 30 convenience stores in Georgia have benefited with improved lighting, including interior, cooler or refrigerator door lighting and outdoor canopy lighting thanks to the lighting efficiency improvements program. The lighting efficiency improvements grant implemented by GACS was designed to have a quick payback period and to establish a revolving loan fund so that future projects have financing available. The upgrades were completed by participating stores without having to pay for upfront costs. The estimated savings yielded over the course of 18 months after the installation is then paid back into the fund by participating stores. 

During the implementation of the upgrades, it was found out that canopy lights were the common choice for the stores. A quick payback for the canopy lights was extremely difficult which prompted the installers to find a better solution. One solution which was first tried in a mart located in Savannah was to cut back on the number of unnecessary LED lamps which helped in bringing down electricity consumption by about 2/3. However a breakthrough and real energy saver came in the form of induction lighting. With induction lighting, electromagnetic fields are used to transfer the power needed to generate light from outside the lamp envelope to inside. Induction lighting extends lamp life and is more energy efficient because of smaller light generated substances. The specially made induction lighting retrofit kit cut down energy consumption by 70% while at the same time costing less than the LED solutions available.
