Hi guys,
First time post here. Im troubleshooting a customers LED channel letter sign and have a question about the driver. Intial problem was dim light. System is about 7 years old outside. Upon inspection, found led modules with some nonworking leds, some working and all dim. replaced all leds with new 12v .72w 2 mods(3leds) per ft, about 75 ft. system still dim. traced back to driver and found that under load that driver was only producing 6 v with 120v at input. removed driver and found not under load it produces 12 v. My question is, is that normal. I did order a new driver, $48, which is, btw, dc 12v/5a/60w. I believe that is fine for this led setup. Would appreciate any input plz. I did visually inspect wiring and didnt notice any problems.
Thanks in advance.
Jim
