While we rarely use our outside light, but our inside lights were really hot. So hot that we couldn't sit on the couch with the light on above us. I replaced all the bulbs with flat LED panels with 48 LEDs each. All cool now, and the converter hardly makes any noise.
As far as warranty coverage, call the dealer and ask. It's possible, and if so they might be able to just send you the light so you don't have to tie up the trailer for 3 weeks waiting.
