Telecoms ♦ news digest directional retrofits such as MR/PAR lamps.
In addition, by leveraging the chromaticity control standard 3-step MacAdam ellipses, the LC series offer high colour uniformity and light quality. The packages also provide low thermal resistance and superior heat dissipation which enable high reliability, and have successfully completed LM-80 testing, a widely observed test method for lumen maintenance developed by the Illuminating Engineering Society.
The Samsung LC series has been available in 2700K, 3000K, 4000K and 5000K versions, with a 3500K version now added. Samsung’s latest LC series also offers a diversity of wattages coming in 13W, 26W and 40W versions depending on the LED product with which the packages are used.
Cree redefines the troffer market
The firm says its new ZR series LED troffer delivers excellent light quality and aesthetics for under $100
Cree says it is redefining commercial lighting with the ZR series LED troffer.
The new troffers deliver a new category of performance, affordability and inspired design.
Featuring Cree TrueWhite Technology, the ZR Series LED troffer delivers superior colour quality (> 90 CRI) in an ultra slim, sleek package at an initial price starting from $99.
commercial usage of 12 hours per day and $0.11 per kWh electric costs.
“It takes more than incremental improvements in performance to achieve widespread adoption of LED lighting. Cree innovation starts with a clean slate, designing a new troffer with an attractive appearance that provides superior light quality, high efficiency and also enables fast installation,” says Norbert Hiller, Cree executive vice president, lighting.
“The ZR Series LED troffer is a winning alternative, offering uncompromised performance and an industry- leading 10-year limited warranty at a remarkably low price,” continues Hiller.
The ZR Series LED troffer’s thin 3.9” height and lightweight design enables faster installation without costly ceiling alterations. Offering a quick and easy one- for-one replacement of inefficient fluorescent troffers in education, healthcare and commercial building applications, the ZR Series LED troffer simplifies installation and significantly reduces labour costs during its 75,000-hour lifetime in all 1’x4’, 2’x4’ and 2’x2’ configurations.
The Cree ZR series LED troffer is sold through Cree lighting sales channels throughout the U.S. and Canada.

Infinera introduces InP based multi-layer automation for transport
The combination of the Infinera DTN-X packet optical transport networking platform with new solutions hope to enable multi-layer automation of Intelligent Transport Networks
Infinera has launched new solutions for service providers planning to simplify the operation of multi-layer transport networks through increased automation.
Cree ZR series troffer
The ZR Series LED troffer cuts energy consumption in half, and with standard 0-10V dimming can accelerate its already rapid two-year payback. This is based on energy consumption and payback calculated against a fluorescent three-lamp fixture (with lamp and ballast equal to 88 system watts) and based on typical
Multi-layer transport networks blend the efficiency of digital switching with the scale of optical switching to create the communication foundation of cloud-based services and the Internet.
The solution includes one of the industry’s first super- channel FlexROADM (reconfigurable optical add drop multiplexer), the first standards based multi-layer control plane for spectrum switched optical networks (SSON)
