Good People, Thanks to the humans that replied on and off-line. Much appreciated.
Have also noted that there has been some interesting discussions on the subject per the proposed Peoples Republic of California Energy Commission regulations for LED luminaires; for example, note this comment to the CEC: http://docketpublic.energy.ca.gov/PublicDocuments/17-BSTD-02/TN222823_20180302T105129_Kelly_Seeger_Comments_Philips_Lighting_additional_comments_on_N.pdf Brian -----Original Message----- From: Brian O'Connell Sent: Wednesday, February 21, 2018 2:14 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: light flicker Does any 60601 collateral standard, address limits for light-source flicker; or have any other requirements for the light-flicker frequencies emitted by a luminaire? Have noted IEC60601-2-41 but do not have it; does it provide light-flicker frequency limits? Am already aware of the TLA stuff in NEMA77 and IEEE1789, and the IEC61000-4-15 'flickermeter' stuff. These standards are contradictory, and the IEEE standard fails to provide any reference to biophysical data that would provide a rationale. And 60601-1 clause 10 does not say much other than the generic response that references the RMF.
