Notes
• Forward voltages are tested at a current pulse duration of 1 ms and a tolerance of ± 0.1 V. Luminous flux is measured at a current pulse
duration of 25 ms and an accuracy of ± 11 %.
(1)
Calculated based on single LED unit.
(2)
V
F
classes are marked at the LED cluster and represent the technical classification only. The single groups cannot be specifically ordered.
