Review on 🚐 Leisure LED 3 Pack RV LED Ceiling Double Dome Light Fixture - ON/OFF Switch, Natural White 4000-4500K, Interior Lighting for Car/RV/Trailer/Camper/Boat, DC 12V, 48X2835SMD by Robert Ducki

These products use a Fresnel lens over the LED that produces a ring-shaped intermittent light pattern with a slight spectral color shift at the edges of the light/dark rings. Sitting under this light is annoying, and if you're doing something that requires special attention, it will cause the viewer's color distortion in addition to uneven lighting. There are no interchangeable lenses for them. Don't buy them, get another brand/type with frosted or plain lenses.
