LEDs SETi & Cascade to
develop UV LEDs for water
purification SETi’s germicidal UV LEDs, comprising aluminium gallium nitride, will be used to provide potable water to small groups from any source of fresh water.
Sensor Electronic Technology, Inc. (SETi) and Cascade Designs, Inc. of Seattle, have signed a Joint Development Agreement to develop the next generation of portable water purification systems for commercial, military and disaster relief/ humanitarian applications.
The water purification systems will use SETi’s germicidal UV LEDs to provide potable water to small groups from any source of fresh water anywhere.
Germicidal UV LEDs are a new technology that offer an alternative to mercury lamps or chemical treatment and enables a compact, lightweight and mechanically robust disinfection solution that can stand up to the rigors of military and humanitarian use and, when powered with an alternative energy source, can offer a sustainable source of drinking water for many months.
Through a development program funded by the National Science Foundation (NSF), SETi has already successfully demonstrated the use of its germicidal UV LEDs in a bench top disinfection chamber. The collaborative effort with Cascade Designs will further this work and lead to the development of the first multi-stage UV LED-based water purification system.
Cascade Designs has forty years of experience developing and manufacturing innovative products for the outdoor and military markets. Under the MSR (Mountain Safety Research) and Platypus brand names, the company has a significant share of the portable, point-of-use water treatment market.
Cascade Designs is the standard issue supplier of sleep pads, snowshoes, camp stoves, and on the move water treatment systems for the U.S. Army and Marine Corps.
Together, the companies believe that UV LEDs, combined with proprietary filtration and absorption technologies, will have breakthrough potential for the military and humanitarian relief efforts.
“We see great potential in partnering with SETi,” says Joe McSwiney, president of Cascade Designs, Inc. “With SETi’s UV LED technology and our experience in designing and manufacturing a broad range of water treatment products, we believe we can develop revolutionary new water treatment systems that will advance the work we’re already doing to supply the U.S. military and bring sustainable relief to people around the world who lack potable water.”
Remis Gaska, president and CEO of SETi agrees. “With a 58

“The CS Series LED Linear Luminaire is poised to revolutionize low and mid bay lighting applications just like the CR Series did for Troffers,” says David Elien, vice president, Cree lighting.
“The Cree CS Series luminaire is unlike any other suspended linear lighting on the market today,” adds Jason D. Curtis, principal, Cardinal Gibbons High School. “We researched the LED market extensively and only Cree offered a solution that delivered high-quality lighting and easy payback. Since the new CS Series is designed for 75,000 hours of life, Cardinal Gibbons High School can benefit from ongoing operational
strong track record of taking new technologies to market, Cascade Designs is the obvious choice for SETi to partner with,” Gaska says. “This collaborative effort will demonstrate the effectiveness in UV LEDs for Sensor Electronic Technology, Inc. disinfection and will not only address the need of the public sector markets, but will also pave the way for the development of UV LED based disinfection products in the private sector.”
Cree’s latest LED linear
luminaire sets records The module, suited to retail and industrial applications, integrates high efficacy, advanced optics and architectural design and is claimed to far outperform antiquated linear fluorescent technology
Building on the success of the CR Series LED Troffer, Cree, has revealed the CS Series LED Linear Luminaire, which delivers fast payback to low bay lighting applications.
Cree says the new high-efficacy suspended linear luminaire uses 40-50 percent less energy than comparable linear fluorescents and delivers an unmatched performance combination of up to 120 lumens per watt, 90 CRI and 75,000 hour lifetime.
Featuring Cree MicroMixing Optics, the CS Series brings a combination of performance, aesthetics, optimal light distribution and affordability to grocery stores, retail, showrooms, schools, offices, warehouses and light industrial environments.
