I have some new led's that I like but the cables going to the brick are really short and I really do not want the brick hanging off the tank. Not sure what they are thinking but 4ft is just way to short. The power brick is supplying 24v 2.5a via normal 5.5mm barrel connections and they make some 6ft extensions. I am aware of voltage drop but would the connections and 6ft really cause any issues, my guess is no but would like some others like @Sral @theatrus @oreo54 to weigh in. My other option is to replace the 24v power supplies with ones that have longer cables but thats not the cheap route, lol...I need about 10ft for one based on how i want to route the cords.
