LEDtronics LED Pendant Lamps Help Central California Town Reduce Energy and Maintenance Costs

March 5, 2012

Joining the ever-growing number of smart cities that have chosen more efficient technology to light their streets and saving money in the process, the City of Carpinteria in November 2011 completed its retrofit project of replacing all its existing city-owned high-pressure sodium (HPS) decorative street lights with energy-efficient LEDs. The lights are located on several blocks of Linden and Carpinteria Avenues in the downtown area and include lights on the Amtrak rail platform and its adjoining public parking lots.

According to the city’s calculations, each of the 199 HPS lamps at 138 watts each consumed 604.4 kWh annually—a total of 120,284 kWh and an energy cost of $15,035 (at $0.125 per kWh, 12 hours of operation each evening). With the switch to the brilliant and more directional LEDtronics 29-watt LED bulbs, the annual energy cost came down to less than $3,160—a dramatic 80 percent savings. In addition, the LED bulb life is four to five times longer than the replaced HPS bulbs, resulting in reduced maintenance costs that yield additional savings.

In addition to the $11,600 savings on its annual energy bill, this reduction in power usage by 96,000 kWh translates into a decrease of its carbon footprint by an estimated 33 tons of CO2 yearly.

“I like the results very much,” said Matthew Roberts, director of the city’s Parks and Recreation Department that installed and maintains the street lights. “The LEDtronics lamps fit into the existing light fixtures with only minor modifications and look great. I think the consensus is that the new bulbs produce fewer glares, are easier on the eyes, and have a very appropriate color temperature for our needs.”

The Santa Barbara County city is a coastal community of 13,040, with small-town charm, beautiful beaches and breathtaking mountain views. It hosts the annual California Avocado Festival.

“All of the lights installed so far have worked as promised,” says Roberts. “It’s great to know our streetlight electrical meters are turning more slowly, saving tax dollars. It’s also nice to know the products were assembled in the USA.” The product was designed and engineered at the LEDtronics factory in Southern California.

The project started in early 2010, when the city began to study the conversion of pendant street lights in its downtown area to LED bulbs that are more energy-efficient, cast a more natural warm light and reduce light pollution. They looked for solutions that were cost-effective, more environmentally friendly and also more night-sky friendly.

After testing the LEDtronics LED30HPS-600-SIW-002-BU pendant lamp for two months, the city applied for funds and received $74,117 from the California Energy Commission under the Energy Efficiency and Conservation Block Grant (EECBG) program from the U.S. Department of Energy, which is part of the American Recovery and Reinvestment Act of 2009 (ARRA). The bulbs are certified “Made In USA.” The total project cost was $78,580.

Carpinteria’s lighting efficiency project is in line with the California Long Term Energy Efficiency Strategic Plan, which holds the state’s local governments to be leaders in energy efficiency by 2020, both for their own facilities and throughout their communities. The city so far has replaced over 90% of its traditional street lights with LEDs.

According to city officials, the LEDtronics LED bulbs were selected because of their high efficiency, appropriate 3000K color temperature, and because they fit inside the existing globe diffusor without significant modification. The new LED bulb also allowed for the elimination of the HPS bulb’s ballast and starter. As well, LED bulbs produce little or no ultraviolet light (UV) which, as generated by the HPS bulbs along with the high heat, causes the polycarbonate globe diffusers to yellow and become brittle.

With longer life for the globe diffusers and reduction of visits to each light by maintenance staff, the 10-year projected cost savings is expected to reach $150,000. This is in addition to the significant energy savings inherent in the LEDtronics LED bulbs that the city has already started to enjoy.

L.A. Museum Hosting 4.5-Billion-Old Specimens Employs 21st Century LED Lighting Technology

January 7, 2011

After five years of restoration, modernization and seismic retrofitting, the historic Rotunda building of the Los Angeles County Natural History Museum in July 2010 reopened with a new face and a whole new set of lighting—decorative LED bulbs supplied by Torrance, California-based LEDtronics, Inc.

Renovation of the 97-year-old Beaux Arts-inspired building was part of a multi-phase, $107-million project that included the modernization of the electrical system to support multimedia presentations and events, improve climate control and enhance exhibition lighting in an energy-efficient manner. Modernizing of the lighting system involved a retrofit from incandescent light fixtures with custom-manufactured LED systems without compromising the historical integrity of the original fixtures, notably in the Rotunda.

LEDtronics provided 90 of 5-watt PAR38-180 Series bulbs and 160 of 1-watt DEC-G25F Series frosted bulbs through the distributor, American Electric Supply of Corona, California, to the contractor of record. The lamps were first installed in summer 2008.

Both types of bulbs offer a color temperature of 3000 Kelvin. Most of the PAR38-180 bulbs were of a narrow beam configuration, and were positioned in a crisscrossing beam fashion around the perimeter of the 57-foot-high Rotunda dome—the centerpiece of the museum building. The rest were medium beam, and were installed in recessed fixtures as down lights around the building’s upper walkway. Use of the 5-watt LED lamps represents a minimum savings of 4,000 watts when compared to the 50-to-60-watt incandescent PAR-style bulbs that might otherwise have been utilized.

The DEC-G25F-style frosted globe lamps were used as accent lighting all around the inside perimeter of the Rotunda. The complete installed set of 1-watt LED bulbs only consumes about 160 watts, compared to the 2,240 watts that would otherwise be consumed had the architect designed in a similar set of standard 14-watt G25 incandescent bulbs.

The LED bulbs were installed not only to reduce energy consumption and improve light quality but also to reduce maintenance costs. Incandescent bulbs would go out often and the poor accessibility made replacing them difficult. Based on the LED’s 50,000-hour operational lifetime and the museum’s weekly hours of operation, maintenance teams will need to replace the LEDtronics lights only about once every 15-plus years.

There is another advantage to the LED switch: The dramatic reduction in lamp-generated heat. This provides major benefits both in terms of much less air-conditioning required to keep the older bulbs cool, and also because keeping the temperature in the rotunda down is important since heat can cause the lead in the skylight to soften.

Originally dedicated when the Natural History Museum opened its doors in 1913, the Rotunda, crowned by the stained-glass skylight, is one of the museum’s most elegant and popular spaces. The colonnaded hall has often been used as a filming location, while the museum’s distinctive main building is on the National Register of Historic Places.

The museum is the largest in the western United States, and its collections include nearly 35 million specimens and artifacts and cover 4.5 billion years of history.

March 1, 2010

Torrance, Calif., Jan. 5, 2010 — LEDtronics, Inc., entering its 27th year of leadership in innovative LED lighting solutions, announces the newest members in its series of high-brightness, energy-efficient LED replacements for A19-style light bulbs for home and commercial use. The DEC-A19-5X1W DécorLED Series comes with softly diffused, precision domed lensing that directs light at a 95-degree beam, and is available in Warm White (3000 Kelvin) and Pure White (6000K). These A19-style LED bulbs offer long-term durability, low power consumption, environmental sustainability and money savings. They run on a flexible voltage range of 85-265 VAC requiring no special adapters, and replace 40W to 50W incandescent bulbs while consuming less than 7 watts of power.

In addition, the series DEC-A19-5X1W DécorLED boasts an outstanding color quality of up to 85 CRI, a horizontal beam spread of around 130 degrees, powerful 416 (XPW) and 340 lumens (XIW) of brightness, easy drop-in installation in existing 26mm Edison or E27 European screw-in base sockets, and sturdy construction with UV-stabilized polycarbonate lens over five 1-watt, high-power Cree XR-E LEDs encapsulated around a unique grill-style, heat-sinking magnesium-alloy housing.

Because LEDs have no filament, their solid-state design renders them impervious to shock, vibration, frequent switching and environmental extremes. With an average lifespan of more than 50,000 hours (5.7-plus years), white LED bulbs operate more than 20 times longer than the equivalent incandescent bulb, eliminating repeated relamping! Unlike compact fluorescents, LEDs contain no harmful mercury, and because they do emit negligible amounts of heat and no ultraviolet or infrared light, they protect what they are illuminating. The DEC-A19-5X1W Series features enhanced passive cooling that reduces junction temperatures, extending the life of the lamp. The fact that they run remarkably cool also means they greatly reduce the fire hazard normally associated with the use of incandescent lamps.

These economical, elegant light bulbs offer a directional light that is perfect for use in recessed lighting, table/floor lamps, accent and decorative lighting, garage or workshop lights, down lights and ceiling cans, marquee signage and retail display. As a matter of fact, they are ideal for use anywhere you are currently using an incandescent A-19-style light bulb, including outdoor applications when contained in a sealed housing.

Since LED lights are 300% more efficient than compact fluorescent lamps, these bulbs are perfect operating on an alternative or renewable energy resource such as solar or wind power, in cold or warm environments.

These maintenance-free lamps come with a 3-year warranty period and CE safety assurance, and are RoHS certified—they adhere to strict European guidelines concerning the Reduction of Hazardous Substances such as lead and mercury. Since they produce no harmful ultraviolet or infrared radiation, they reduce light pollution, and are compatible with the international “Dark Skies” initiative.
