Figure 18: Relative luminous flux or radiometric power vs. forward current for red, red orange and amber
at T_J = 25ºC maintained, test current 350 mA.
Note for Figure 18:
Driving these high power devices at currents less than the test conditions (350 mA or 1000 mA) may produce
unpredictable results and may be subject to variation in performance. Pulse width modulation (PWM) is recommended
for dimming effects.
