XLamp® CXB2530 LED

rELativE LuMinous fLuX vs. CurrEnt (t

J = 85 °C)

The relative luminous flux values provided below are the ratio of measurements of the CXB2530 LED at steady‑state operation at the given

conditions, divided by flux measured during binning, which is a pulsed measurement at 800 mA at T

J = 85 °C.

For example, at steady‑state operation of Tc = 25 °C, I

F = 1080 mA, the relative luminous flux ratio is 140% in the chart below. A CXB2530

LED that measures 3200 lm during binning will deliver 4480 lm (3200 * 1.4) at steady‑state operation of Tc = 25 °C, I

F = 1080 mA.
