Hello Kathy, I assume that you are designing products to IEC 60950. However, which edition? There is a big difference between the 2nd and 3rd editions when it comes to LEDs.
IEC 60950 3rd edition does not specify LEDs having to be compliant with IEC 60825-1, only lasers (see clause 4.3.13 and Annex H).

(I restated the question.) Our design engineers are using LED more often and have been asked if the LED are approved by IEC 825. Question: When does an LED need to be evaluated to IEC 825 standard? Are there any other industry limits for specific LEDs? It seems that in the past LEDs were basicly ignored except for color issues. What is the current thought or rule on this issue?
