Product description
The XLamp®CXA2520 LED array expands Cree’s family of high‑flux, multi‑die arrays, offering high performance in an easy‑to‑use platform. With XLamp LED lighting‑class reliability, the CXA2520’s uniform emitting surface enables both directional and non‑directional lighting applications and luminaire designs. Available in (2‑step)3‑step and 4‑step color consistency, and featuring a 19‑mm optical source, the CXA2520 brings new levels of flux and efficacy to this form factor.
The CX Family LED Design Guide provides basic information on the requirements to use the CXA2520 LED successfully in luminaire designs.

Relative luminous flux
The relative luminous flux values provided below are the ratio of:
● Measurements of CXA2520 at steady‑state operation at the given conditions, divided by
● Flux measured during binning, which is a pulsed measurement at 550 mA at TJ = 85 °C.
For example, at steady‑state operation of Tc = 25 °C, IF = 725 mA, the relative luminous flux ratio is 140% in the chart below. A CXA2520 LED that measures 2100 lm during binning will deliver 3300 lm (2940 * 1.4) at steady‑state operation of Tc = 25 °C, IF = 725 mA.

Relative luminous fLux
The relative luminous flux values provided below are the ratio of:
● Measurements of CXA2540 at steady‑state operation at the given conditions, divided by
● Flux measured during binning, which is a pulsed measurement at 1100 mA at TJ = 85 °C.
For example, at steady‑state operation of Tc = 55 °C, IF = 1760 mA, the relative luminous flux ratio is 140% in the chart below. A CXA2540 LED that measures 4600 lm during binning will deliver 6440 lm (4600 * 1.4) at steady‑state operation of Tc = 55 °C, IF = 1760 mA.Cree LED Chip manufacturers
