XLamp® CXB1816 LED
ꢀELꢁtivE LuMinous fLuX
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.
