Although I expect TC62 will do its own thing re IEC 60601, IEC SC77AWG2
is also studying new flicker phenomena.

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:

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.
Thanks,
Brian
