LED lights and hang ups

[Gerald Corey]

We have 2 10 ft arches, each running 7 strings of mini LED lights. The entire arch seems to stay on barely visible during a sequence. Is this a board problem or what would you suggest. Occasionally parts of the 2 20ft arches, each running 14 strings of 100 regular mini lights will stay on until they are activated again later in the sequence. The 20 ft arches are each on a separate controller with one string per channel. The 10 ft arches share a controller with one arch on channels 1 - 7 and the other on channels 9 - 15.

We would like to know more about the LEDs before "stocking up" on after Christmas sales! Any theories?

Thanks

Have had this same problem with 40 amp solid state relays, them not wanting to turn off when under almost no load like those LED lights you have. I used to use solid state relays ( connected to the outs of a stereo ) to energize PLC inputs. Anyway, I had to load up the solid state relay with a string of incandescent lights to get the relay to turn on and off sharply with the music. Try connecting a string of incans to a channel that does not want to turn off and see what you get.
