Therelativeluminousuxvaluesprovidedbelowaretheratioof:
• Measurements of CXA2590 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 1200 mA at T

chart below. A CXA2590 LED that measures 9,000 lm during binning will deliver 10,800 lm (9,000 * 1.2) at steady-state
operation of Tc = 55 °C, I
