Why is there a five-second Delay from the time you turn the switch on to the time the lights come on?

My lights come on instantly but my switch is right at the ballast / transformer. Can't image any line length from switch could cause a current delay. Lights are not on a 3-way circuit are they? Just thinking of some kind of reason for voltage drop / current leak. What is the environment for the ballast. I could see a delay if it was in a cold location. Assuming none of those circumstances apply I'd say you have a defective ballast.

Can i replace my 12v-20w halogen bulbs with led bulbs of equivalent brightness without changing the transfomer?

No, this is an electronic transformer ( to power halogen/ xenon bulbs), and requires a minimum load in order to operated. You need to find a LED Driver that are comparable w/ the type of bulbs you are using.

will this replace mdl corp 316-0004

I do not know, I am not an electrician. Please use the pics to research. Thanks.
