Hey guys,

Before I get started I'm not the brightest crayon in the box with electronics. Disclaimer out the way.


So I built a led strip light to supplement my t5 that I'm going back to. I chopped up one of my old eBay lights to use the drivers.(pic below). I would like to be able to get the bars to dim up and down throughout the day.

I have located the ground and 10v line as it was labled on the pcb board attached to potentiometer. There is a third line labled on and off that I have no idea what to do with. I assume that third line is what turns driver completely off when potentiometer is turn all the way down.

My question is

1. do I need to hook that line up when I program to ra? If so to where.

2. Being as it that I'm going to plug up in relay box and can I just kill that outlet in the event I don't need that line?

3. How can I tell if it's analog or pwm signal?

With a lot of the Chinese BlackBox lights sold on E-Bay the On/Off gets joined together so the lights have power when not plugged into the potentiometer.

This thread explains it better and has a link to the original post on another forum about it,

You probably will need it, but if you don't yes you can kill it.

The newer dimming modules have jumpers inside that you can switch from Analog to PWM.

The drivers are probably built into the lights.

Can you post a picture of the potentiometer on the PCB that you talked about?
