Philips street light surge protector (Patreon)
Content
Another posh surge unit to rival the MeanWell unit. But this one was MUCH easier to open.
It also has a better and simpler failure indicator with just a single low current LED that everyone will ignore anyway. If I was cynical I might think that this unit is just a way to get the light beyond the warranty period.
There's always an issue mixing electronic power supplies with traditional transformers and inductive ballasts. The collapsing field of a chunky inductor can induce a significant voltage spike that might not bother other discharge lamps, but may make an electronic driver shit its little silicon pants.
