I replaced all of the wedge style bulbs in my RV with this. Having already tried a couple of different LED bulbs, I was concerned about two things. One was the color of the light it produced because different types of white LEDs can have too much blue in the light they produce. The color temprature (in kelvin) is where you find this information. These bulbs Kelvin rating are very easy on the eyes. the second thing was how much light the put out in comparison to the standard incandesent bulb. Again, these are performing great and as far as my eyes can tell, they are very compareable to the old incandesent bulbs they replaced. Now that I do not have any incandesent bulbs in the RV, our battery will last longer and the generator will not have to be run as much to keep them charged while dry camping.
