RELATIVE LUMINOUS FLUX - CONTINUED

The relative luminous flux values provided below are the ratio of:

• Measurements of CXB3590 at steady‑state operation at the given conditions, divided by

• Flux measured during binning, which is a pulsed measurement at 1200 mA at T

J = 85 °C for the 72‑V CXB3590.

Using the 72‑V CXB3590 LED as an example, at steady‑state operation of Tc = 25 °C, I

F = 1400 mA, the relative luminous flux ratio is 120%

in the chart below. A CXB3590 LED that measures 11,000 lm during binning will deliver 13,200 lm (11,000 * 1.2) at steady‑state operation

of Tc = 25 °C, I

F = 1400 mA.
