Mass preheat fluorescent EOL « on: October 23, 2025, 01:02:37 PM » Author: WorldwideHIDCollectorUSA
Has anyone seen a large number of fluorescent lamps exhibiting the typical magnetic preheat EOL flashing at the same time? This video is a prime example of a large gathering of EOL fluorescent lamps flashing endlessly on magnetic preheat ballasts: https://youtu.be/GMlfcnYQ4O4?si=Tb7G3Xu1clIinlHP

Looks like a brownout rather than massive EOL.

However I have never seen this happening to multiple lamps at the same time.
