Typical Relative Luminous Flux

Relative Luminous Flux vs. Forward Current for CoolWhite,

NeutralWhite, WarmWhite, Green, Cyan, Blue and Royal Blue

Junction Temperature, TJ = 25°C

Notes for Figures 16 & 17:

Driving these high power devices at currents less than the test conditions (350 mA or 1000 mA) may produce unpre

dictable results and may be subject to variation in performance. Pulse width modulation (PWM) is recommended for

dimming effects.
