Review on 💡 GRV T10 921 194 LED Bulb (2nd Generation) Pack of 10 - Super Bright AC/DC 12V-24V for RV, Boat, Landscape, Ceiling Dome Interior Lights - Cool White, 24-5050 SMD Lamp by Adam Mazie

I am very satisfied with these lights. All of the bulbs worked as expected and I didn't find them too difficult to install (no more difficult than a standard 921 bulb). They work amazingly well, use 1/5 the wattage of incandescent bulbs and don't get hot. I did a lot of research before ordering LED bulbs and finally settled on 5050 LEDs because of their wattage, color and high customer rating. The manufacturer claims 320 lumens for these 24 LED lights and they are definitely brighter than the incandescent bulbs I replaced. I've installed them in all of my RV's main lights, two lights per light, and the result is amazing. For installations that do not require this brightness - under the counter, above the bed, in storage compartments etc. - I ordered a variant with 12-5050 LEDs. I am also very happy with them. Something to note: if you're ordering LED lights for a camper van, don't buy the 12v versions. I see a lot of Revain products being sold that specifically state they won't be used above 13v should be 14.5 volts, which will likely overheat and/or damage it.
