LED's stay on (dimmed)

I have noticed that some of my LED strings stay on (dimmed) even when the channel is off or the show ended. It's only hapening with LED's - how do I fix this problem?

It could be a load issue (as in too little). To check, add a string of minis or some other lights to the channel to see if it will turn off. If so, you will need to add resistance to the channel either by way of additional lights, a snubber, or even a plug in room freshener.

Are you using standard inlet cords for the controller, or home built? Several people who have had LED lights staying on have discovered that they had hot and neutral backwards to the controller. This results in live power always going out the neutral lead to the LED, and they were running dimly on just the power leaking out of the string to ground.

My controller power cords (in and out) are from LOR.

I found that when I plug in a string of mini's to the end of the dome LED string, they turn off. What's a snubber, better yet how do I build one?

My string of blue LEDs is a different story, six consecutive bulbs are always on dim out of 100. When I plug in the mini's a bunch more turn on dim that were off. Unplug the mini's they turn off again, the six remain on.

Do you have one of those cheap outlet testers? The ones that plug into a three prong outlet, and give you a few status LED's with a chart to interpret if it is wired correctly? I'd use one of those on the outlet you are plugging into. The strand that gets more LEDs turned on when incandescents are plugged in really doesn't sound normal at all.

klb,

Your thinking the same thing I am about the outlet tester.

Hi OP,

You are discribing the exact same things that happened to me. But my problem is that I was not thinking and I slapped on a cheap non-polorized plug. So my hot was going to the neutral input to the controller. If you have a 3 prong outlet and same for a power cord (yes you did say that you do). Then it has to be the outlet is wired wrong. I agree with klb and get and use the tester to tell you if your outlet is wired wrong. Once you have the hot lead going to the hot terminal, I will almost bet you 100% that this will fix your problem.

Been there, done that..

Thanks for the tips on what to look for! I'll hit it Saturday when I have some daylights hours to look at things. Something about holding a flashlight in my mouth while scrunched behind a hedge up against the house and squating down while I work with wiring. I don't want to test the GFCI that way...
