XLamp® CXB2540 LED

rELativE LuMinous fLuX

The relative luminous flux values provided below are the ratio of measurements of the CXB2540 LED at steady‑state operation at the given

conditions, divided by the flux measured during binning, which is a pulsed measurement at 1100 mA at T

J = 85 °C.

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

F = 740 mA, the relative luminous flux ratio is 80% in the chart below. A CXB2540 LED

that measures 5225 lm during binning will deliver 4180 lm (5225 * 0.8) at steady‑state operation of Tc = 25 °C, I

F = 740 mA.
