Caught my desk lamp throwing a disco party with the ceiling fan

Turns out a 60hz LED bulb and a fan spinning at 240 rpm make this weird strobe effect that gave me a headache for two days before I counted the blades and looked up the math online.

That math adds up to a real world headache machine. Swap that bulb for a regular one and save yourself the trouble.

3am bulb swaps are the worst, @verafoster that's basically a guarantee you'll wake up the whole house fumbling for tools. Better to just grab a pack of regular bulbs and avoid the midnight math altogether.
