Fishing line, lures, and hooks were caught on the power cord of several underwater fishing lights.For all 6, once ballast was replaced they did not appear to have further issues. The ballast was inside the underwater light on the other 2. 6 people had problems with their ballast going out, we discovered 4 people left their ballast mounted on an open dock and it was not under any sort of weather cover.A boat prop shattered the glass cover in an underwater green fishing light the light had to be replaced.Crabs and/or fish gnawed at the power cord causing a short in one persons light the cord had to be repaired.7 people tried these - one person's lasted two weeks and all the others lasted a couple days. Don't trust the "Amazon Special" cheap fishing lights when leaving underwater permanently.mercury vapor bulbs reportedly break very easily and had to be replaced several times per year (some had to replace several times per month).When run dusk to dawn, the lenses stayed clean.

They were not always present on the light lens though. Even if the lights were working properly, barnacles were present on the light housing when checked. Barnacle growth was a common problem with all of the underwater green fishing lights.Note: this was an older subdivision, I would guess most people have lived here at least several years. Every single person with underwater green fishing light(s) has replaced at least one of their lights at least once since owning their house.There were 4 people with above water green fishing lights that have not had any issues at all.There was an even split of mercury vapor and LED green fishing light users.There were 32 people polled as a part of this experiment and there were 15 different brands/types of fishing lights. We conducted an interesting experiment where we polled people from a coastal neighborhood that were using green fishing lights at their home - to find out what some common problems were. Coastal Neighborhood Experiment: Green Fishing Light Maintenance We put together a guide to maintenance-free green fishing lights, but it looks like the only tried-and-true removal method is a jar of elbow grease and a good chisel to clean them off. Some of the best quality underwater green fishing lights will burn off the growth, but if the dusk to dawn sensor fails, a circuit breaker trips or you simply forget to leave the light plugged in before you know it there's a bunch of barnacles that have covered the lens and no amount of heat will break them free of their cement-like hardened super glue.


The number one struggle with underwater green fishing lights is the everlasting battle with continuous barnacle and marine growth.
