More than 2 years now with my conversion; over 25 incandescents replaced with LEDs, all cheap, all from either Amazon or eBay, some 48-5050 panels, some 13-5050 COB style, some strips (16' 300-3528 on the awning, 16' 600-3528 inside, cut into 4' sections for under cabinet use). They are used about 1 3-day weekend per month, sometimes dry camping (12VDC), sometimes with full hookups (13.8+VDC). The strip lights actually get the most use, as they put out the most light over a large area. In fact, the strips lights are the best part of my conversion.
Results? Not one failure, no RFI, no dimming, no heat runaway.
