Select the Right 921 LED Bulb RV (4 Tips)

Now, the challenging part about buying a RV light bulb would be to have the know-how in choosing the best brand with the most suitable features. With that, we’ve come up with criteria to help you pick out the best 921 led bulb RV for your vehicle.

Here are the factors to consider:

  • Brightness and Intensity

When measuring the brightness or strength of the bulb, you would use lumens to measure it. In general, the higher the lumens, the stronger the light the bulb would emit. Now, the typical number of lumens that a 921 LED bulb for RV would have is around 200 to 220 lumens. So, if you’re looking for a strong 921 LED bulb RV light, make sure the lumens fit this range.

  • Color

Another thing that you can take note of would be the color of the bulb. The cool thing about LED lights is that they come in a variety of colors for you to choose from. That’s why they make great decoration pieces. They come in blue, red, green, and the traditional white. The 921 LED bulb RV light you choose will really depend on how you want the feel of your RV’s interior to be.

  • Wattage

The beauty of LED lights is the fact that they can save you a lot of energy. While they require small wattage as compared to halogens, they give off more lumens. For instance, a typical 220 lumen LED bulb would only need a wattage of around 1.5 or 2 watts. Compare that to a typical incandescent bulb that would need around 20 watts to give off the same number of lumens. In the long run, 921 LED lights are more energy efficient.

  • Lifespan

The last thing that you need to take into consideration would be the lifespan of the bulb. This refers to how long the bulb would last before eventually burning out. LED bulbs usually have a long lifespan as compared to halogens.

The 921 LED bulbs, in particular, are extremely long lasting. The typical 921 led replacement bulb RV light can last from 40,000 to 50,000 hours depending on the brand you buy. You need to take that into consideration so that you’ll know how long you can keep it running until you have to replace it with a new bulb.
