Notes:

1.Luminous intensity is measured with a light sensor and filter combination that approximates the CIE

eye-response curve.

2.θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

3.Luminous flux measurement tolerance:±15%.

4.Forward voltage measurement tolerance:±0.15V.
