God, LEDs must be the worst scam foisted upon us by governments. Flicker, lies about the lifespan, and now you say I must replace the entire lamp when it fails rather than just the bulb.
...Interference with medical equipment (this lab I knew found out that their EEG malfunctioned when the new lamps were on...)
How would you instead check EMI - in general? (I am not a specialist in this area.)
This would be a really poor driver, effectively using the AC freq. and shutting off w/ each cycle/zero cross. Unfortunately, many are exactly like that. However - some cameras do have compensation for exactly this issue, and they may hide it.

Use an AM radio. (That would depend on the frequency and what not, but AM radios are a pretty neat trick to check)
I miss the days of a restive wire shoved into the AC circuit.
