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

•

Mꢀasurꢀmꢀnts of CMT2850 at stꢀady-statꢀ opꢀration at thꢀ giꢁꢀn conditions, diꢁidꢀd by

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 = 25 °C, I_F= 1500 mA, the relative luminous ﬂux ratio is 120% in the chart below. A CMT2850

LED that measures 7050 lm during binning will deliver 8460 lm (7050 * 1.2) at steady‑state operation of Tc = 25 °C, I_F= 1500 mA.
