My 2011 Georgetown came with double bulb pancake lights on the ceiling and small round halogen bulb fixtures under the cabinets and over the couch. I replaced all of the bulbs with 48 led panels I bulk purchased from China. These panels have no voltage regulation on them and, if run on over 12V burn up quickly. To avoid problems with them, I installed a DC-DC buck regulator in each fixture that I set to 11.2V. The regulators and bulbs cost me around $5 / fixture, a reasonable cost.
When I removed the fixtures, the one that was on the most had turned the ceiling under it brown from the heat of the bulbs.
I also added an additional LED fixture in the hall, just outside the sliding bedroom door. It nicely lights the hall wardrobe that was, as delivered by FR, a black hole. I used the air conditioner duct to run power from the nearest ceiling fixture to it.
Contact the LED Dealer that was at the Goshen Frog Rally vender area,"Cabinbright" led lights! Call Joe,good guy! Convert over all your lights! Youroo!!
I replaced the bulbs in a couple of the lights that we use the most,,, I got the bulbs from a local RV dealer,,, I know they are cooler & use less power,,, but am not sure they are as bright an the old bulbs were ??? I do like the LED in the range hood !!!
WE have our Windjammer on order and haven't been able to determine what model tail-light fixtures are on there. From looking at online photos, it appears they are Peterson 457 series and in that case, take 1157 bulbs.
Hoping to try these units I located online since the placement of the LEDs would appear to mimic the location of the filament in a regular bulb and thus work well with the Lens covering the bulb/fixture.
