Woohoo!
I've been fighting with these for a while. Hubby and I just completed a marathon troubleshooting session.
In the royal blue string, there was one bad connector and one bent connection pin. In the white series there was a bad dimming splice.
It looks like I'll be dimming the whites a lot more than the royal blues. My white ratio is higher than it really should be. But, I've got the Apex all programmed and figured out for this, so that'll be easy.
There are four blue LEDs that are being run off of a little moonlight driver.
Now I just need to get them mounted.
(The concise details of this build, and the materials list, will be posted at a later date)
