Lighting Efficiency Series: Stretching the savings
Everyone is always saying the best way to save energy is to turn off your lights and equipment when they are not being used. It is a simple concept but not so easy to put into practice. It requires a cultural change that is hard to implement and even harder to maintain.

Indoor LED Lighting With the XLamp MX-6
"We are impressed with the Cree XLamp MX-6 LED," said Sunny Tsai, CEO of TESS, an innovative LED light bulb manufacturer. "The LED's performance is
striking, and Cree's small bins make it easy for us to deliver a consistent product for our customers."
"With the addition of the XLamp MX-6 LED, we now have the most diverse family of lighting-class LEDs in the industry," said Paul Thieken, Cree marketing director, LED components. "The XLamp MX-6 LED can provide better design options for indoor applications, including under-cabinet, retail displays, LED light bulbs and fluorescent replacements."
The XLamp MX-6 LED provides up to 130 lumens for cool white and 107 lumens for warm white at 350 mA. The XLamp MX-6 LED can also reduce luminaire and lamp manufacturing costs through an increased shelf life with reduced moisture sensitivity, and the smallest warm white bins in the industry, enhancing LED-to-LED color consistency.

XLamp XP-G LED lighting-class LEDs now commercially available
"Cree's XLamp XP-G cool white LEDs set a new standard for LED performance," said David Chow, president, 4Sevens, LLC. "For our flashlights, the XLamp
XP-G LED was a clear choice because of its high lumen output, unmatched efficacy and compact package size."
This level of performance can potentially reduce the required number of LEDs, as well as the size and cost of LED fixtures. High efficacy at lower current (up to 132 lm/W typical at 350 mA) can lower the total power requirement for a portable or solar lighting application, which can reduce the amount of solar cells or batteries needed.
"This establishes a new level of performance for LEDs," said Paul Thieken, Cree director of marketing, LED components. "We now deliver lighting-class efficacy at 1A drive current. In addition, we have begun offering limited samples of an S2 flux bin, providing up to 400 lumens at 1A. We target availability of XP-G neutral and warm white LED samples by end of calendar 2009."
XP-G LEDs extend the leadership of Cree's lighting-class LED family, giving lighting designers a wide range of price and performance options that all share a common package footprint. The cool white XP-G LED is available now.

Energy efficient T9 LED light tubes
The T9 light tubes are easy to install and are available in three white colour temperatures, 3300k (cool white), 4200k (neutral white) and 6500k (warm white) and are sold in lengths of 1 to 5 feet. These 24V tubes are available in both 50º and 100º viewing angles and each tube includes two mounting hardware options which can rotate up to 120º. Whether your application is in need of the 50º or 120º angle of light, either angle delivers high lumen output which can be dimmed to any desired brightness using our low voltage remote LED dimmer module. Engineered to last in excess of 50,000 hours, these aluminum tubes reduce maintenance hassles and replacement cost issues typically associated with fluorescent tubes. The T9 LED lights also contain no lead, mercury or glass, making handling and disposal less of a concern, and also is RoHS compliant.

New and improved PAR20 LED bulb for indoor lighting applications
The PAR20 LED bulbs are engineered to last 50,000 hours. This extremely long life will virtually eliminate maintenance costs, and will help you see a return on your investment as LED Bulbs typically offer a payback period of less than 2 years. EnergyLED light bulbs are also environmentally responsible as they consume less energy than standard bulbs and disposal is also not a concern because the bulbs are lead free and contain no mercury. These lights generate very little heat and emit no UV rays which make them an ideal choice for the museum and retail industry. In applications where vibration is a factor in the life of a light bulb, LED lights are the perfect solid state choice. These lights are also perfect for store fronts and point of purchase displays which are typically illuminated for long hours.

Solar powered parking-lot light
According to Ted Lattimore, Carmanah CEO, Carmanah and frog design shared a common goal throughout the design process: to present a powerful new lighting alternative characterized by elegance of design and efficiency of operation. "We knew this light would be special - delivering big system performance in the smallest form factor yet — so when it came to the design, we wanted the very best," said Lattimore. "Working closely with the team at frog, we settled on a unique design that reflects the essence of renewable energy: clean, simple, practical and efficient. Although it's a tough, high output, industrial-strength light, the quality finish and distinctive, contemporary styling would look great just about anywhere," said Lattimore. "But best of all it performs better than anything in its category — it's a practical, cost-effective renewable energy alternative."
Since 1969, frog design has pioneered some of the world's most groundbreaking designs for trendsetting companies such as Apple, Logitech, Microsoft and Sony. In discussing the partnership with Carmanah, Doreen Lorenzo, president of frog design, said, "The opportunity to partner with Carmanah to create a solution that is both beautiful and functional was one our designers embraced. It is a great example of innovation positively affecting our environment."
Built on nearly two decades of experience developing self-contained solar-LED lanterns and beacons for the marine, traffic and aviation industries, Carmanah's solar-powered street, parking lot and urban lighting products help businesses and communities introduce outdoor area lighting wherever it's needed, without trenching, cabling, grid access, or a monthly utility bill. With more than a quarter of a million units deployed, Carmanah products are widely used and recognized around the world for durability, performance and dependability - operating safely and reliably in some of the world's most challenging environments. As an environmentally responsible alternative, Carmanah's solar-powered EverGEN 1710 area light is assembled using safe, recyclable materials in strict accordance with the European Union's guidelines for the Restriction of Hazardous Substances in electronic equipment (RoHS).
The EverGEN 1710 solar light is scheduled for availability in early 2010. For more information, visit the EverGEN 1710 product page on the Carmanah web site — www.carmanah.com.

Cree launches LED product characterization tool
Cree, Inc., a market leader in LED lighting, launched the Product Characterization Tool, an interactive LED design tool that simplifies the task of translating nominal LED performance to real-world conditions.
The online tool, accessible via www.cree.com, allows users to easily characterize any XLamp LED over a wide range of operating conditions, including drive current, flux bin, price and junction temperature. It also calculates metrics such as lumen output, lumens per watt, lumens per dollar and more.
Cree's Product Characterization Tool (PCT) introduces advanced functionality not commercially offered by any LED supplier, the company claims. PCT can perform simple LED system design based on a target total lumen output, calculating parameters such as number of LEDs required and total system efficacy. The calculated system parameters take into account electrical, optical and thermal losses associated with LED system performance. In addition, PCT allows users to compare up to three different XLamp LED configurations at once, empowering customers to best choose between the industry-leading XLamp XR, MC and XP package families.
"The Product Characterization Tool acts like an interactive data sheet, giving users a more intuitive way to design LED systems using XLamp LEDs," said Paul Thieken, Cree, marketing director for LED components. "Determining even basic LED system parameters like efficacy with only data sheet graphs and characteristics used to be a time-consuming process. Cree is moving the LED lighting industry forward by simplifying the process to just a few clicks of the mouse."
More information, including login instructions for the Product Characterization Tool, can be found at www.cree.com/pct.
