I have been reading as much as I can about LED ucls and think I know how they work, but am still a bit confused. I get the whole wire > transformer > light connection thing, but what I am wondering is if it is possible to buy an LED light that has the transformer built in, so you can direct wire it?

We are doing most of the work on our kitchen reno, but hired an electrician to replace all the wiring (it was alum and we wanted copper). Anyway, he talked us into ucls and hardwired for them (2 runs - well 1 plus an extra light) on a non dimming switch. We initially thought we would put in Xenon, but are now considering LEDs. Is it possible to make the switch now? The wires are sitting under the cabinet, waiting for a light. Should we just get Xenons? or does a product that I am describing exist?

Thank you!
