relatiVe luminOus Flux - COntinued

The relative luminous flux values provided below are the ratio of measurements of the CXB1507 LED at steady‑state operation at the given

conditions, divided by flux measured during binning, which is a pulsed measurement at 200 mA at T

Using the 36‑V CXB1507 LED as an example, at steady‑state operation of Tc = 105 °C, I

in the chart below. A CXB1507 LED that measures 900 lm during binning will deliver 1080 lm (900 * 1.2) at steady‑state operation of Tc

= 105 °C, I
