RELATIVE LUMINOUS FLUX
Therelativeluminousuxvaluesprovidedbelowaretheratioof:
• Measurements of CXA1850 at steady-state operation at the given conditions, divided by
• Flux measured during binning, which is a pulsed measurement at 1400 mA at T

chart below. A CXA1850 LED that measures 5590 lm during binning will deliver 6708 lm (5590 * 1.2) at steady-state
operation of Tc = 55 °C, I
