LED strips sometimes powers on, sometimes it doesn't
Posted: Mon Apr 05, 2021 4:48 pm
I just built a shelf with 9 LED strips for my plants, but I have a very weird issue... Sometimes it powers up and sometimes it doesn't. The first time I plugged it, it worked perfectly but after 15 minutes it shut down. Tried to power it on again but it refused to. So I waited 2 hours and then plugged it back in and it worked perfectly. I let it on for 2 hours without any issue so I assumed it was working. So I went to sleep and the next day I tried to plug it in and it didn't light up. I haven't touched anything between my tests.
So I thought the driver could be faulty. I bought another one but I have the same problem. I also tested it with 3 different power outlets (with and without a GFCI, no difference, and the GFCI doesn't trigger)
What could cause this issue if it's not the driver? If it was wired incorrectly I assume it wouldn't power at all, but the issue is intermittent. I have triple-checked all wiring and everything seems to be wired correctly (I can't show a picture because the wires are hidden inside an aluminum bar)
I tried with a potentiometer at 25% 50% 75% and 100% ... also tried without a potentiometer, and also tried just connecting the 2 dim wires together.
I also tried to disconnect all of the strips and tried to power just one strip ... nope, didn't work
1x XLG-150-H-AB
9x BXEB-L1120Z-50E4000-C-B3
16AWG wires in parallel (a mix of hard wires and repurposed computer/monitor power cord)
