Thꢀ XLamp® CXB1820 LeD Array is a
mꢀmbꢀr of thꢀ sꢀcond gꢀnꢀration of
thꢀ CXA family that dꢀliꢁꢀrs up to 30%
higher efficacy and up to 20% higher
lumens than the first generation in the
samꢀ LeS. Thꢀ highꢀr pꢀrformancꢀ

Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a tolerance of ±2 on CRI
mꢀasurꢀmꢀnts. Sꢀꢀ thꢀ Mꢀasurꢀmꢀnts sꢀction (pagꢀ 14).
Cree XLamp CXB1820 LED order codes specify only a minimum flux bin and not a maximum. Cree may ship reels in flux bins higher than the minimum
specified by the order code without advance notice. Shipments will always adhere to the chromaticity bin restrictions specified by the order code.
For 80 CRI minimum LeDs, CRI R9 minimum is 0 with a ±2 tolꢀrancꢀ. For 90 CRI minimum LeDs, CRI R9 typical is 60.

The relative luminous flux values provided below are the ratio of measurements of the CXB1820 LED at steady‑state operation at the given
conditions, divided by the flux measured during binning, which is a pulsed measurement at 550 mA at T = 85 °C.
J
For example, at steady‑state operation of Tc = 55 °C, IF = 650 mA, the relative luminous flux ratio is 120% in the chart below. A CXB1820
LED that measures 2100 lm during binning will deliver 2520 lm (2100 * 1.2) at steady‑state operation of Tc = 55 °C, IF = 650 mA.
