Ben,

I see 2 possible problems.. I do not think the FL4 should be grounded.. The other issue could be you are dropping the voltage on the LED's to low.. May be a CV setting or the resistor is to big.. Other than those it should work fine..

Tony,

The Black/White wire on the TCS decoders is gound for there low voltage regulator circuit for LED lighting..
