Philips Lumileds Introduces Luxeon TX

Philips Lumileds has introduced the new Luxeon TX emitters for a variety of directional and omnidirectional led lighting applications. The Luxeon TX LEDs come with a choice of 3- or 5-step MacAdam color definition. According to the company, the LEDs either have 10 to 20 percent brighter lumen output or have more CRI options than the Luxeon T. The LEDs have versions with new 85 minimum CRI options in 2700, 3000, 3500, 4000, and 5000K color temperatures.

“These emitters are truly transformative in that they enable customers to achieve performance metrics -- such as a true 50W 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 at 70 CRI are taking advantage of the Luxeon TX 360 lm output at 1.0A and 85˚C to decrease overall system cost, but have the ability to drive the same part @350mA to deliver 155 lm/W LED efficacy and enable streetlights with a system efficacy of more than 120lm/W.”

The Luxeon TX platform is available in a range of correlated color temperatures and CRIs for downlights, high bay and low bay lighting, indoor area lighting, outdoor lighting and replacement lamps. In addition the company has added a minimum 85 CRI option.

“Designers have typically had to choose between the lower efficacy associated 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, ” Hartnet said.

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).
