Next generation of high-power of flux emitters aim to transform directional luminaires

“These emitters are truly transformative in that they enable customers to achieve performance metrics – such as a true 50 W equivalent MR16 lamp at 2700K that meets ERP/DIM2 requirements – which LEDs simply could not meet previously,” said Kathleen Hartnett, Product Line Director at Philips Lumileds.

“We use the term ‘extreme efficacy’ because of the remarkable performance customers can expect from these emitters,” said Hartnett. “For instance, outdoor fixture manufacturers who need 4000K a t 70 CRI are taking advantage of the LUXEON TX 360 lm output @1.0 A and 85 ̊C to decrease overall system cost, but have the ability to drive the same part @350 mA to deliver 155 lm/W LED efficacy and enable streetlights with a system efficacy of more than 120l m/W.”

The LUXEON TX platform is available in a range of CCTs and CRIs to satisfy the most exacting requirements of downlights, high bay and low bay lighting, indoor area lighting, outdoor lighting and replacement lamps. In addition, for improved design flexibility, Philips Lumileds has added a minimum 85 CRI option so designers can further differentiate their product lines.

“Designers have typically had to choose between the lower efficacy as sociated with a 90 CRI LED or the poorer color rendering associated with an 80 CRI LED. Now LUXEON TX 85 CRI emitters bridge that gap by providing high CRI with increased efficacy in a full CCT range from 2700K to 5000K.”

For applications that require a minimum 90 CRI, LUXEON TX delivers up to 100 lm/W warm white light (3000K CCT, 90 CRI and 700 mA at 85 ̊C).This level of
efficacy at 90 CRI enables superior performance for luminaires that must adhere to increasingly stringent lighting standards such as the CEC’s California Quality LED Lamp Specification.
