The relative luminous flux values provided below are the ratio of measurements of the CMA2550 LED at steady-state operation at the
given conditions, divided by the flux measured during binning, which is a pulsed measurement at 1400 mA at T = 85 °C.
J
For example, at steady-state operation of Tc = 55 °C, IF = 1700 mA, the relative luminous flux ratio is 120% in the chart below. A CMA2550
LED that measures 6850 lm during binning will deliver 8220 lm (6850 * 1.2) at steady-state operation of Tc = 55 °C, IF = 1700 mA.
