Note:
1. The radiant intensity, I

, in watts per steradian, may be found from the equation I
e
= I
v
/h

, where I
v
is the luminous intensity in candelas and h
v
is the luminous ecacy in lumens/watt.

, where j
V
is the emitted luminous ux, I

Notes:
1. Derate linearly as shown in Figure 4.
2. For long term performance with minimal light output degradation, drive currents between 10
mA and 30 mA are recommended. For more information on recommended drive conditions,
please refer to Application Brief I-024.
3. Operating at currents below 1 mA is not recommended. Please contact your local representa-
tive for further information.
