    Any one else ever had this problem when using LOR or anything else. For some reason during fade the lights flicker like a short instead of getting dimmer and brighter!! ANy fix for this or am I out $300 bucks?

    Try a long fade from 0 to 100% or toy with them in the manual control if you have that in LOR. If it seems to work it is probably from the sensitivity of the triac. I use Vixen and found that on some LED's I had did the same thing with my old programs, but if you adjust them they had seemed to work for me. The latest vixen has intensity settings I believe that will help with that. I am going to download it tonight and check it out.

    This could also be a load issue. For a SSR based dimmer to work properly they need to have a heavy enough load. LEDs because of the small current draw can cause dimming issues like this. As a test, if the other suggestions don't correct this, connect a 100W light bulb to the string. This is called a "ghost load" and should smooth out the dimming of the entire string and make things work correctly.

    A 100-watt bulb is a lot more than a "ghost load". That will draw over eight-tenths of an amp by itself.

    A lot of folks seem to have success using a C-7 bulb which is only about .053 amps.

    When you normally deal with 8-20A loads it is. ;)

    Also, I had this problem when trying to use a cheap USB-RS232 converter. Must be a total POS, because dimming looked horrible.

    you probably have half wave LED's. always check the box when purchasing LED's. Full wave have a nice dim to them.

    I don't think you can get full-wave LED strings from the local stores.

    But adding a single C9 to your LED strings will fix this problem. I run some cheapy LEDs on my display and noticed I only have this fading/flickering problem with the Ace Hardware 200ct LED C6 strings (4 strings in series).

    Good luck,

    Another thing you can try is using a terminator (resistor across the plug to give it more of a ghost load)...I've heard of this issue alot with LOR and dimming.....
