Intematix Expands Lighting Grade LED Line: Cetus E-Series Demonstrates Industry-Leading Efficacy

Intematix Corp., a leading innovator in phosphors, LED components and solid state lighting modules today announced the release of a new series of high-efficiency power LEDs. The new Cetus "E-series" products boast efficacies of up to 100 lumens per watt (lm/w) for the cool white versions, and 97 lm/w for warm white, and will facilitate wider adoption of LEDs in general and outdoor lighting.

All models feature Intematix' advanced phosphor technology, providing a high-efficacy and low-cost combination that addresses key needs of luminaire designers.
The standard CRI version of the E-series offers a combination of high-lumen output and cost-effectiveness that is particularly attractive to outdoor lighting manufacturers, all of whom are striving for LED luminaires that are both attractively priced and efficient in operation. The higher CRI models, due in June, extend the range to include interior and architectural general lighting applications. Available standard CRI models include:
• The C6060E high-flux model rated at 700mA drive current, achieving 190lm typical in cool white, 185lm typical in warm white per LED.
• The C5050E 1W LED with maximum cost-effectiveness, delivering 100lm typical in cool white and 97lm in warm white. Its 10V forward-voltage (Vf) specification is ideal for direct drive 12V applications such as landscape lighting.
• The C7676E, a 1W to 2W, 100lm/W LED with a 51Vf specification simplifies 110/220V direct drive applications.
According to Intematix' Director of Marketing, Ilkan Cokgor,  "Wide area and outdoor lighting are applications where LEDs outperform the incumbent technologies in lifetime, maintainability and energy costs, while generating much higher quality light. The continuing challenge has been the initial acquisition costs of current outdoor luminaires, which has negatively impacted payback periods. Intematix' Cetus E-series sets a new benchmark for lumens per dollar, which will enable our customers to lower their costs and enhance ROI for their end-users."
Intematix' high-quality chip-on-ceramic LEDs are characterized by excellent heat management and luminous efficiency enabled by Intematix' well-recognized patent-backed phosphor technologies. The Cetus E-series LEDs are available in 5000K and 4000K cool white, or 3000K and 2700K warm white. Standard CRI versions of all models are available now, while versions with CRIs greater than 80 are scheduled for production availability in June of this year.
"The ability to offer high efficiency, cost effectiveness, and a range of colour temperatures carries little market impact without being able to back that up with product consistency," commented Intematix' Chief Technical Officer, Dr. Yi-Qun Li. "While the full Cetus line uses ANSI standard bins, our specific binning process assures customers will receive superior colour and brightness uniformity both within a shipment and from shipment-to-shipment."
Intematix' complete line of packaged LED lamps, modules and integrated light-engines will be on display in booth number 3109 at this year's Light Fair International, being held May 5-7 at New York's Javits Convention Center.
