Notes:

1.

θ1/2 is the angle from optical centerline where the luminous intensity is 1/2 the optical centerline value.

2.Luminous intensity is measured by a current pulse of 10ms at a tolerance of ±15%.

3.The typical data of Luminous Flux can only reflect statistical figures, actual parameters of individual product could differ from the typical data.

For the purpose of product enhancement, the typical data is subject to change without prior notice.

Notes:

1.Chromaticity coordinates are measured by a current pulse of 20ms with a tolerance of ±0.02 in X and Y color coordinates.

2.Forward voltage is measured with a current pulse of 10ms at a tolerance of ± 0.1V.
