Hi all, I have a quick question regarding a used Kessil 360 WE. I bought it from a respectable member of local reefers so I did not test it with him prior to purchase. When I hooked it up at home and no light. When I checked and found out that he provided me with a 24V power supply and the Kessil needs a 19V. I bought a replacement 19V and still no light. Would the 5V difference enough to burn the light OR it's dead prior to my trying to turn it on? At this point is there any chance to salvage the light or it's a goner now? TIA
