Hello chaps,
Would very much appreciate your advice on some problems we are having with the spot lights in our house. In most rooms there are 4/5 spot lights (50 watt), connected via a dimmer & transformer. They are JC94001 lights.
Over the past year are so, they are all slowly starting to have problems & fail (in all rooms except one).
I have had a look inside, and it appears that the blue wire connecting to the bulb holder have a burned/black appearance to them (look closely at wire in ceiling photo).
In addition, the metal connections to the bulbs are blackened as well (see photo). If I replace the bulb, the light starts working again for about a week, then the same thing happens over again.
my questions are:
1) What is causing this? (A friend has suggested that since the lights were installed before a lot of building work, a lot of dust got inside the connectors to the spot lights, causing heat build up, hence the burned appearance to the cables.(
2) What should I do? - ? replace the defect ones with new units? will the same thing happen again?
3) How on earth do you remove them from the ceiling?!
any advice would be much appreciated!
