I have about a million G4 halogen light fixtures on my boat. so obviously, converting to LEDs would have a big effect on my power budget
. When I first bought the boat, I bought LED units from five or six different manufacturers, from dirt cheap to very expensive. I figured I would experiment
, and then make a big order from that manufacturer who seemed to make the best product.
Well, I made a hash of it - I forgot which went where. The very expensive ones simply didn't fit - they had big heat sinks. All of the units have performed flawlessly over a couple of years of fairly intense use (I spent at least 3 months a year on board) with zero failures and no difference in light quality. The conclusion I come to is that the el cheapos are perfectly fine.
