*1 The luminous intensity

IV is measured at the peak of the spatial pattern which may not be aligned with the mechanical axis of the LED package.

Luminous Intensity Measurement allowance is ±10%.

θ1/2 is the off-axis where the luminous intensity is 1/2 of the peak intensity.

*3 Measurement Uncertainty of the Color Coordinates is ±0.01

Note : All products confirm to the listed minimum and maximum specifications for electric and optical characteristics, when operated at

20mA within the maximum ratings shown above.

All measurements were made under the standardized environment of Seoul Semiconductor.
