Troubleshoot Light set
Hi, any bro expert in aquarium lighting can give me some advice on troubleshooting of light set?
1) How to verify the ballast / e-ballast is not working (beside swapping with a confirm working set) by measuring it output voltage? (i.e. is the output voltage of the ballast in AC / DC? Can we measure its output voltage level without any load using a voltmeter? How?)
2) Is there any wiring diagram for PL and FL lighting that can reference?

Actually I got this rainbow T5 NO 4 tube light, 2 tubes in the middle cannot light up.Originally Posted by richietay
I have checked and confirmed that the middle 2 tubes are working fine. It has 2 e-ballasts (think so, cause it is not the normal metal ballast that require starter) and each ballast is used to power up 2 tubes (left side 2 and right side 2). Theoretically speaking if any of the ballast spoilt, the 2 tubes on either the right or left side will not light up and shouldn’t be the 2 tubes in the middle.
Any idea what went wrong?
