Review on 💡 ROBERTSON Fluorescent EBallast RSW234T12120 RSW240T12120: Reliable & Efficient Lighting Solution for Fluorescent Tubes by Richard Gaines

I have had to replace my old F40T12 4-lamp Advance ballasts with proprietary wiring harnesses. The old ballasts had yellow, red and blue wires, exactly the same as the description and schematics on Robertson's website. The correct ballasts from Robertson arrived the next day however they have yellow, red, blue and BROWN wires. , and the circuit diagram was not compatible with the old ballasts. I'm not sure why the same model number has a different design and schematics on the website and in real life. To return.
