So having been tied up with work lately I neglected to check the skimmer collection cup the past 2 days and last night I guess it started to spill out and dripped onto the ac/dc adaptor for my lights shorting it out... hopefully it's just the power block I have to replace but shopping around to try and find a replacement that doesn't cost half the price of buying a brand new light I have run into a few questions mainly when it comes to the DC barrel plug it self and determining the size so I get an exact match any one with any experience in this sorta of thing that can offer guidance?
