Review on Super Bright T10 921 922 912 LED Bulbs - Soft White Light for 12V RV Ceiling Dome Light - RV Interior Lighting for Trailer, Camper, Boat - 600 Lumens - Pack of 10 by Ulysses Fincher

I've tested them with a bulb RV already in a typical 2-light dome light, with another LED in a Cobb style configuration. The color was good, I ordered a warm white and it was a similar warmer shade along with the others. I don't like "bright white" or other high Kelvin lights, especially for my RV that I vacation in. The bluer the light, the more it prevents your body from relaxing. LEDs always have the worst color rendering (i.e. CRI, not the color of the light but how well you can see all the colors on the color wheel when using the light). ) compared to incandescent bulbs, but they were similar to others. I also compared the brightness using a foot candle measurement app on my phone left in the same spot, same distance from the light, with the same colored objects next to it for color comparison. Incandescent lights produced 36-foot candles at that exact spot. The Cobb style only produced 13. The Paddle style produced 78 in the same place. I then turned the paddle upside down for more reflection and less direct light and saw about 39-foot candles that looked like an incandescent bulb. In a 3-light chandelier fixture above a dining table, two LEDs cast the same amount of light onto the worktop, but this gets much more into the walls. I actually had to turn the oars away from the common area to avoid blinding myself when I saw them straight ahead. Globes have a slightly odd light pattern, but my wife didn't notice until I pointed it out. I haven't measured the wattage, but both LEDs use and heat up significantly less than incandescent bulbs, and if you're thinking of replacing them, do it. These LEDs are in all the lights in the living room, with the blocks just above the beds being turned upside down to diffuse the light. The Cobb headlights will be going into the storage bays as it took me too long to start returning them.
