The bathroom in my bungalow is fitted with ceiling down lights but my knowledge of these is far from good. There are three lamps in the ceiling but one lamp doesn’t last long and I don’t know why. Has each light got its own transformer or does one transformer provide all three? The lamp I have used is an ECO Halogen MR16 12V 35W 38° (according to the label). I believe this to be what the other two lamps are. Also, can anyone guide me as to where to go to learn more about ceiling down lights as I was born before WW2 and am still mentally stuck on tungsten! I’d be grateful for any help or advice.
