Fluorescent bulb morse code? Help decode.

Office bulb, the one right over my desk, started pulsing last Tuesday in what LOOKS like a pattern. I recorded 40 minutes on my phone. Transcribed the pulse intervals. If this is morse: short-short-long-short, pause, long-long-short, pause, short-short. I don't know enough morse to read it. Does anyone. Before I take this to facilities.

short-short-long-short = F. long-long-short = G. short-short = I. so: FGI. that could be initials, an acronym, or coincidence. what's the building for the bulb. a GIF would be an interesting anagram.

@Delacroix_Decoder the building is owned by an LLC whose parent company's initials are — wait for it — GFI Holdings. GFI. Exactly those three letters reordered.

a fluorescent-ballast signature drift can occur in a 60 Hz flicker pattern when the ballast is near end-of-life. that's the boring explanation. the less-boring explanation is that the ballast is flickering a COHERENT MESSAGE tied to the building ownership. check the adjacent bulbs.

the ballast explanation is plausible for a random pattern but not for a pattern that spells something meaningful. probability math says coincidence for 3 letters is roughly 1 in 17,576. not impossible. just very suggestive.

Checked the adjacent bulbs yesterday. Two of the four were pulsing DIFFERENT morse. I'm transcribing now. Give me a day.

backup your phone recording to multiple drives before you transcribe. if they change the bulbs, your recording is the only evidence.

backed up. three drives. one encrypted. bulb was replaced this morning. i was not notified. facilities says it was 'routine.' nothing about the previous bulb was routine.
