Hi I am new to this forum :D and would like to ask a question about my ceiling light that was installed just over a year ago. I have 9 halogen bulbs on my ceiling light which were running bright up to about yesterday!! they still are working but have gone extremely dim. I do not have a dimmer switch so dont know what has happened. Will I have to replace my ceiling light or is there anything else I can do?? :?:
Halogen bulbs operate at 12 volts and a transformer is required to bring down the 110/220v to 12 volts. Since all 9 bulbs has gone dim at the same time, I presume they are all connected in parallel to a single transformer. This presents quite a reasonable load to the transformer and might have caused it to fail. I suggest you distribute the load to let's say, 1 transformer for every 3 bulbs to minimize stress on the transformers.
not all halogen lights are 12v with a transformer, in fact most multilight single fitting centre lights are 230v so don't need a transformer at all, if you don't know the voltage / wattage remove a lamp and see if info printed on side.
