Toshiba LED Street Lamps Chosen By CPS Energy To Replace 20,000+ HPS Lamps In San Antonio, Texas
Toshiba International Corporation – Toshiba International Corporation (TIC) announced that its Toshiba TGT LED Luminaires will replace over 20,000 high-pressure sodium (HPS) street lamps in San Antonio, Texas. CPS Energy selected Toshiba’s LED roadway lighting after extensive investigation and experimentation with multiple LED luminaire options. Ultimately, Toshiba was selected for its product performance and LED technology expertise, which includes development of LED products that will be communications-enabled, allowing for connection to the Smart Grid and other communications technologies.
The Toshiba TGT LED Luminaire is a direct replacement for high-intensity discharge (HID) lighting, such as high-pressure sodium or metal-halide, which require frequent maintenance and consume up to 70% more energy than LED light sources. In contrast, Toshiba’s TGT LED luminaire has a rated life of 100,000 hours L85, and the photocells have a rated life of 15 years, which means the TGT luminaire lasts up to 5 times longer with a lower lumen depreciation than metal-halide and twice as long as high-pressure sodium products. San Antonio’s existing 250-watt HPS luminaires consume 310 system watts and are being replaced by Toshiba’s 100-watt 42-chip TGT LED luminaires. Thanks to product durability and low energy consumption, LED lighting provides one of the lowest life cycle costs of any lighting technology.
“We were incredibly pleased with the quality of light from the Toshiba product. The change-outs implemented to date have resulted in a marked improvement on light distribution and color rendering,” said Richard Lujan, Manager for Standards and Specification at CPS Energy.
In addition to the energy and maintenance savings, Toshiba TGT LED Luminaires provide high color rendering, uniformity and small target visibility, all of which enhance public safety. Conventional HPS luminaires produce a low color rendering, which may make it difficult to discern true colors of cars or surroundings, whereas LED luminaires produce a more accurate color rendering. Additionally, LED luminaires produce superior light uniformity, which means the light is directed where it’s needed with less light loss or misdirected light and more uniform light levels with better average to minimum footcandles, as compared to HPS luminaires. The monochromatic nature of HPS also makes the ability to detect contrast difficult. This affects a driver’s ability to see small objects or obstructions on the road, which could represent a safety hazard. Toshiba TGT LED Luminaires also outperform conventional HID luminaires by providing superior vertical luminance. This is an important safety feature because it affects the ability to see faces when in a parking lot or on sidewalks.
“We are committed to the value this product brings to the marketplace – not only as an incredibly energy-efficient, low-maintenance product, but as a superior light source that enhances visibility and contributes to a community’s improved quality of life,” said Peter DellaPezze, Vice President of Marketing and Product Development, Toshiba International Corporation LED Lighting Systems Division. “We also value the relationship we have with CPS Energy as we work together to develop lighting solutions that take advantage of all the capabilities LED technology can offer progressive communities such as San Antonio.”
With a 120-year lighting heritage in Japan, Toshiba Corporation is one of the largest lighting companies and LED lighting manufacturers in the world and is focused on developing innovative lighting solutions that capitalize on the possibilities that LED technology provides.
