at f = 1 kHz, DF = 6.7%.
2. Refer to Figure 6 to establish pulsed operating conditions.
3. Derate linerally as shown in Figure 5.
4. The transient peak current is the maximum non-recurring peak current the device can withstand without
damaging the LED die and wire bonds. It is not recommended that the device be operated at peak currents
beyond the Absolute Maximum Peak Forward Current.

Notes:
1. The dominant wavelength, λ
d
, is derived from the CIE chromaticity diagram and represents the color of the device.
2. The radiant intensity, I
e
, in watts per steradian, may be found from the equation I
e
= I

, where Iv is the luminous intensity in candelas and η
v
is
luminous ecacy in lumens/watt.
3. The approximate total luminous ux output within a cone angle of 2θ about the optical axis, φ
v
(2θ), may be obtained from the following formula:
