XLamp® CXB1820 LED

rELativE LuMinous fLuX

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

J = 85 °C.

For example, at steady‑state operation of Tc = 55 °C, I

F = 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, I

F = 650 mA.
