Replacing 12v halogen downlights for 240v LED downlights

Anonymous user 23/02/2024 - 2.52 PM

I am replacing six 12v/50w halogen downlights with six 240v/5w LED downlights on the landing. Each light had its own 240/12v transformer which I removed and then attached a 240v connection. I did this individually and there were no problems until I did the last light. When I did this, all the LED lights were suddenly a lot dimmer. However if I keep a halogen light with its transformer there, the remaining LEDs are fully lit. I have moved the transformer to another light and the same situation occurs. Any thoughts on why I have this problem and cannot install all the LED lights? Any help would be appreciated.

Are you a tradesperson and able to answer this question?

The only thing that would make all the other lights go dim is if there is a series resistance, ie a fault condition.Turn off the circuit breaker which feeds the lights in question (don't just turn off the light switch!) and check the polarity and live / neutral connections are correct on all the lights before continuing. As you are now making the light fittings 230V AC make sure each fitting is earthed and verify this....or get a professional electrician in! :-)

Circuit not wired properly from the outset, such there is some sort of backfeed creating a series circuit.
