Lumileds — LUXEON HL2X High-Power LEDs

Lumileds LUXEON HL2X High-Power LEDs

The Lumileds LUXEON HL2X line of high-power LEDs are the new breakthrough emitters that raise operational light output.

When it comes to white light sources for illumination, light output and efficiency have long been the first two criteria of product selection. Though many quality of light factors are important, light output and efficacy are still the starting point for product evaluation.

In the mid-2000s, Lumileds introduced hot testing at 85°C. It simply made sense to evaluate the light output and efficiency at operating temperature, not at a laboratory specification which is not easily replicated in the real world. Now, with the introduction of the LUXEON HL2X LED, Lumileds is resetting the way the industry measures and evaluates light output from an optical perspective, emphasizing a new measure: usable lumens.

It turns out that in many cases, not all the light produced from an LED, even at operating temperature, can be used in the application. For instance, an LED might produce 300lm at 85°C, but optically, because of the native radiation pattern, only 270lm are available to illuminate the target.

Enter LUXEON HL2X

LUXEON HL2X is a 2mm² CSP high-power emitter intended for outdoor and industrial applications such as streetlights and high-bay luminaires. Development of this new LED started with consideration of the application challenges faced by luminaire engineers, whose priority is in-application light output.

No other LED in this segment provides as many usable lumens as the LUXEON HL2X. By giving special attention to beam angle, field angle, color over angle and optical efficiency, Lumileds has paved a new path for evaluating LED performance based on usable light in the application.

To support design implementation using the LUXEON HL2X, Future Lighting Solutions (FLS) offers optical systems expertise and a portfolio which enables it to work with luminaire manufacturers to optimize their outdoor and industrial luminaires for visual and optical performance. Lumileds recommends working closely with the FLS team to ensure that you achieve the greatest value from your LED selection.

We think that, on evaluation, you will find that LUXEON HL2X delivers superior results.
