Review on 💡 10-Pack Super Bright 921 LED Bulbs for RV, Camper, Trailer, Motorhome, Marine Boat Dome Interior Lights - Natural White 3500K by Geoff Yates

When I first opened the box, I was concerned because all the "light bulbs" were shaken out of the box (not opened), so I was afraid of damage. However, I used 18 out of 20 during installation and they all worked 100% - no crashes or dim lights. The PCBoard material for the pins is a bit tricky to install as the edges are sharp (compared to smooth glass) but they got it all installed. Some of them had to be adjusted as contacts were not being made, but with a wiggle/movement they all turned on at once. They were brighter than the bulbs they replaced, and with a few bulbs the converter fan wouldn't come on (an indication that little power was being used). I definitely recommend these for replacing incandescent bulbs - they use a lot less power and are brighter. I have used other "warm white" reading lights as they are more natural and easy on the eye. As for durability and longevity, I can't say for sure - they were only installed last week.
