A ceiling light was fitted in my upstairs landing about a year ago. It was sold by B&Q (Domus I think it was called) and it has 8 x 10W LEDs that are attached to the bottom of 8 wires that hang from the metal circular enclosure that is fitted to the ceiling. The light came supplied with a round 35-105W/VA transformer and it worked without fault for about 6 months, then it suddenly started dimming randomly until it finally wouldn't turn on at all (so I'm assuming the transformer blew). It was out of guarantee as it wasn't fitted as soon as it was purchased.
I checked the light all over and couldn't see any problems. The bulbs were all correct and the wiring all in place and without any obvious fault. So I went and bought a replacement HALOLITE 35-105W/VA rectangular transformer (which fit inside the light casing perfectly) from screwfix and the light was working perfectly again... for about 3 months. Now it's started dimming and turning itself off randomly. Sometimes it will work for 15 minutes and sometimes it will illuminate for 1 second before it goes dark or dims. I'm only guessing that this is due to the transformers overload protection, but why would it be overloading when it is only outputting 80W and the transformer is capable of up to 105W? The transformer also has Short-Circuit and Thermal Protection.
I have checked the lighting circuit and there doesn't seem to be any problems with it that are obvious. The other 4 upstairs rooms lighting do not dim or have any problems whatsoever so I am sure it's just to do with this light. I could go and buy a new one, but I am very curious to know what the problem is and if it can be permanently fixed, or if it is the light that is duff then what's wrong with it?
Thoughts would be much appreciated. Cheers
