i know this is trivial but driving me up the wall. I have two 48 inch lights (coralife) I use one controller to adjust and turn on lights. Upon shutting down the system I can only get one light to turn completely off and the other light has just a small blue glow to the blue lights. Hardly noticeable but I would like to see no lights when I hit the orange on off switch. Sequence I use is go minus (-) button until 10, then press blue light on/off button, then hit orange on/off. Any help would be great, thanks.
