LED linear luminaire outperforms linear fluorescent technology

May 02, 2012 // By Christoph Hammerschmidt
Building on the success of the CR Series LED Troffer, Cree, Inc. introduces the CS Series LED Linear Luminaire to deliver fast payback to low bay lighting applications. According to the vendor, the high-efficacy suspended linear luminaire uses 40-50 percent less energy than comparable linear fluorescents - it delivers up to 120 lumens per watt, 90 CRI and 75,000 hour lifetime.

Featuring Cree MicroMixing Optics, the CS Series brings an extraordinary combination of performance, aesthetics, optimal light distribution and affordability to grocery stores, retail, showrooms, schools, offices, warehouses and light industrial environments.

The CS Series is designed for low maintenance and long life – lasting up to three to four times longer than standard fluorescents. The luminaire introduces a simple yet efficient optical design approach that integrates an upward-facing LED light strip with Cree TrueWhite Technology and an ultra-lightweight upper reflector, featuring all-new Cree MicroMixing Optics for precise optic control. The CS Series comes standard with 0-10V dimming control to five percent and features a seven year warranty.

Payback calculations compare the Cree CS18 LED linear luminaire with an industrial 4-lamp T8 fluorescent linear fixture of comparable light output. The calculations also assume a typical grocery retail space of 125 units, 24-hour per day usage, $.11 kWh energy costs and relamp maintenance. The result is estimated payback of less than 2.5 years.

New, innovative Cree MicroMixing Optics are formed from thousands of tiny impressions imprinted on the state-of-the-art highly reflective polymer material. Unlike direct-view LED solutions, this multi-faceted pattern blends and softens the intense light and redirects it with precise control and color mixing. The result is beautifully balanced white light with optimal distribution within the desired area.

The CS Series will also be demonstrated at Cree's lighting booth #3008 at Lightfair International in Las Vegas, May 9-11.
