Introduction:
Test conditions of dimmable lighting equipment are unclear in IEC 61547 for dimmable
lighting equipment with dim level other than 50 % ± 10 %. Some HID control units have only
one dim level, for example 65 %.
Present text, Clause 7, second paragraph, first sentence:
“Equipment including a regulating control shall be tested at a light output level of 50 %
± 10 %.”
Interpretation for equipment which could not fulfill the test dim level conditions:
If a light output level of 50 % ± 10 % is not available for equipment including regulating
control, the test shall be done at the level which is closest to 50 %. If two steps equally distant
to 50 % are available, the lower level (< 50 %) shall be used for the test.
