I have already got installed 12v down lighters with 1 transformer per light. The transformers are 20-60VA.
I have just purchased 3W LED lamps (mr16) to replace the 20w 12v halogen lamps. When i put the LED lamps in the fitting they came on fine for about 5 mins then started to flash then went off and dont work anymore.
I have contacted the seller and he has said that it is because the transformer is too powerfull??? and it should have a minimum of 7 3W lamps connected to 1 transformer so that there is a minimum load of 20W on the transformer!
My understanding about transformers is that they only give out what is pulled from them up to their maximum rating.
Am I right or can some one explain???
