My under-cabinet LEDs in the kitchen are out due to a dead
transformer, or "driver" as they call it. It's an Ohmtronic that
lasted 4 years, which seems on the short side to me. Prising off the
plastic cover revealed a patch of soot where something had burned out.

Any recommendations on brands to get or avoid? If you've had one
working for more than a few years and know what type it is, please let
me know.

Thanks.
