RELATIVE LUMINOUS FLUX - CONTINUED

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

• Measurements of CMB1306 at steady-state operation at the given conditions, divided by

• Flux measured during binning, which is a pulsed measurement at 200 mA at T

J = 85 °C for the 36-V CMB1306 LED.

Using the 36-V CMB1306 LED as an example, at steady-state operation of Tc = 25 °C, I

F = 400 mA, the relative luminous flux ratio is 200%

in the chart below. A 36-V CMB1306 LED that measures 1000 lm during binning will deliver 2000 lm (1000* 2) at steady-state operation

of Tc = 25 °C, I

F = 400 mA.
