1000 Low dim light not bright twinklers

My husband and I have spent the entire weekend stringing lights around the house and through the yards, front and back we set up several blow up displays and some standing ornaments in the yard all with lights. My husband fancys himself as a handy man and for the most part he is.

We have at least 50 or more strings of lights on the house and garage and garden shed. There is maybe 20 or strings of lights on the trees around the yard and all the ornaments and blow ups have lights. We bought high end outdoor power bars and ran them all to a control panel an electrician friend had built for us.This in turn is wired into the main fuse panel in the garage which has heavy power as my husband puts it . He has a work shop in the garage with lots of power tools. So the question of power should not be a problem but it is.

Heres our problem when we turn on the lights they are very dim . We have tried shortening the extension cords taking off lights we've tried cutting the number of lights down but the only thing that seems to work is taking the LED lights out of the equation. when we take out the led and leave only the older strings of lights everything works fine but when we use the newer ones it all dims out. hes out there now trying to hook up only the led to see if they will work alone has anyone had this problem and can you tell us what we can do to run both the old lights and the new.

UPDATE :

Paul's still out in the yard without any luck yet hes tried the control panel removal , didn't work, he's now checking each strand of lights to see if there's just a bad strand. will keep you posted please more ideas would be appreciated.
