XLamp® CXA1816 LED

Relative Luminous Flux

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

• Measurements of CXA1816 at steady-state operation at the given conditions, divided by

• Flux measured during binning, which is a pulsed measurement at 450 mA at TJ = 85 °C.

For example, at steady-state operation of Tc = 105 °C, IF = 380 mA, the relative luminous flux ratio is 80% in the chart below. A CXA1816

LED that measures 2100 lm during binning will deliver 1680 lm (2100 * 0.8) at steady-state operation of Tc = 105 °C, IF = 380 mA.
