Notes:
1. Tolerance for luminous intensity measurement is +/- 15%
2. The luminous intensity is measured on the mechanical axis of the lamp package.
3. The optical axis is closely aligned with the package mechanical axis.
4. LED light output is bright enough to cause injuries to the eyes. Precautions must be taken to prevent looking directly at the LED with unprotected eyes.

Notes:
1. The reverse voltage of the product is equivalent to the forward voltage of the protective chip at I
R
= 10 m
2. 2q
1/2
is the off-axis angle where the luminous intensity is ½ the on axis intensity
3. The chromaticity coordinates are derived from the CIE 1931 Chromaticity Diagram and represent the perceived color of the device.
4. The radiant intensity, Ie in watts/steradian, may be found from the equation Ie = Iv/h
v
, where Iv is the luminous intensity in candelas and h
v
is the
luminous efficacy in lumens/watt.
