Perhaps, this is why equipping yourself with knowledge is vital. So, let’s not waste time further and explore the factors to consider while purchasing a LED bulb replacement for an RV!


Remember, when purchasing an LED replacement bulb, lumens are the first aspect that you should inspect. That’s because the lumens represent the brightness or intensity of luminosity, which we believe is the prime concern of your purchase.

According to the general rule, the greater the number of lumens, the better the emitted light would be. A standard LED replacement bulb for RV 921 has about 200 to 220 lumens.

Thus, the minimum acceptable value for lumens is 200. However, if you want super bright lights and a stronger LED replacement bulb, then you should seek values greater than this.


To some, the color of an LED is the least important factor to consider. However, the color of the LED bulb can alter the atmosphere as well as your mood. LED bulbs are available in multiple colors, such as blue, white, yellow, red, and many more.

Power Consumption

Similar to other bulbs, the 921 bulb draws energy to function. The process gets referred to as power consumption. When selecting a LED bulb for an RV, it is important to aim for low power consumption options as it will conserve energy and our resources.

Color Temperature

The color temperature of an LED bulb tells the warmness or coolness of the light. It gets measured in Kelvin.

From 2700K-3000K, the emitted light is soft and warm. From 3500-4100K, the light is neutral white. From 5000-6500K, the radiated light is cooler and resembles daylight.

Apart from being a matter of preference, the color temperature selection depends on your activities. While warm lights are suitable for homes, cooler lights are best for offices and workspaces.


At times, the poor lifespan of bulbs results in frequent replacements that can be hectic. So, if you want a long-lasting solution, then it is better to select the LED bulbs that have a longer lifespan, such as 50,000-hours.
