The maximum current rating of the CXB1816 is dependent on the case temperature (Tc) when the LED has reached thermal equilibrium
undꢀr stꢀady-statꢀ opꢀration. Thꢀ graph shown bꢀlow assumꢀs that thꢀ systꢀm dꢀsign ꢀmploys good thꢀrmal managꢀmꢀnt (thꢀrmal
interface material and heat sink) and may vary when poor thermal management is employed. Please refer to the Mechanical Dimensions
section on page 12 for the location of the Tc measurement point.

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
measurements. See the Measurements section (page 21).
Cree XLamp CXB1816 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 tolerance. For 90 CRI minimum LEDs, CRI R9 typical is 60.
** Flux values @ 25 °C are calculated and for reference only.

The relative luminous flux values provided below are the ratio of measurements of the CXB1816 LED at steady‑state operation at the given
conditions, divided by flux measured during binning, which is a pulsed measurement at 450 mA at T = 85 °C.
J
For example, at steady‑state operation of Tc = 25 °C, IF = 500 mA, the relative luminous flux ratio is 120% in the chart below. A CXB1816
LED that measures 2100 lm during binning will deliver 2520 lm (2100 * 1.2) at steady‑state operation of Tc = 25 °C, IF = 500 mA.

Thꢀ CXB family of LeD arrays can includꢀ oꢁꢀr a hundrꢀd diffꢀrꢀnt LeD diꢀ insidꢀ onꢀ packagꢀ, and thus oꢁꢀr a hundrꢀd diffꢀrꢀnt junction
tꢀmpꢀraturꢀs (T ). Cree has intentionally removed junction‑temperature‑based operating limits and replaced the commonplace maximum
J
T calculations with maximum ratings basꢀd on forward currꢀnt (IF) and case temperature (Tc). No additional calculations are required to
J
ensure the CXB LED is being operated within its designed limits. Please refer to page 2 for the Operating Limit specification.
Thꢀrꢀ is no nꢀꢀd to calculatꢀ for T inside the package, as the thermal management design process, specifically from solder point (TSP) to
J
ambiꢀnt (Ta), remains identical to any other LED component. For more information on thermal management of Cree XLamp LEDs, please
