LED Replacement Bulbs for RV 921 Buying Guide

Why Use LED Bulbs in your RV?

If you haven’t switched to LED lights in your RV, then this is definitely the right time to do so, and for several different reasons. For starters, LED bulbs offer a long service life compared to incandescent bulbs, and emit the same amount of light, while using significantly less energy. This not only makes them extremely environmentally friendly, but also greatly reduces RV battery drain, which will mean you can keep the temperature of the camping fridge down to keep the beer cool!

What to Look for in RV 921 LED Bulbs?

When shopping for the best 921 LED bulbs, you need to first stop thinking about watts to determine the brightness of the bulbs, but rather focus on the lumens.

Watts vs. Lumens

Watts are a great predictor of how bright an incandescent bulb will be, but not for LED lights, given they draw less energy.

For example, an LED bulb that emits similar brightness as a 60-watt incandescent bulb will only draw between 8 – 12-watts power. You can determine the brightness of the respected 921 LED light by the number of lumens it offers, where the higher the number, the higher the brightness level.

Color of 921 LEDs  

With incandescent bulbs, you can expect a warm yellowish hue, but another noteworthy feature of LEDs is they offer a wide range of colors. 921 RV LED lights can display an impressive color range, starting from purple to red to a wide spectrum of whites and yellows.

Choosing the right color from the many options can be a bit overwhelming, but the most preferred and commonly used colors are bright white aka daylight, and warm white or soft white.

Soft white and warm white 921 Led bulbs emit a yellowish, candle like glow similar to incandescent bulbs, whereas you can expect a whiter light with bright white or daylight labelled 921 LED lights.

Speaking of the label of 921 RV LED bulbs, it indicates several key specifications of the bulb such as the color temperature measured on the Kelvin scale. To ease your buying decision, and to avoid any confusion, the lower the color temperature number, the yellower (warmer) the light.

For example, most RV 921 replacement bulbs mentioned on this list feature a color temperature between 2500k to 3500k, which is equivalent to a soft, white light. If you want a light that’s shines extremely bright, you will have to step it up a few notches with a 5000k 921 RV light.

Energy Efficiency

One of the downsides of LED lights is that they are expensive to buy upfront just like hybrid cars, but on the brighter note are much cheaper to operate over the long term. For example, a 60-watt incandescent bulb used for approximately three hour per day will add roughly $8 to your energy bill.

Contrarily, the same 60-watt LED bulb will consumer just 8-watts of power, and add roughly a dollar to your energy bill. Since 921 LED bulbs are connected with a 12-volt electric socket in your RV, this means less battery drainage, but longer operation times.

Service Life

Another great feature of 921 RV replacement bulbs is that they aren’t just a great choice when it comes to energy efficiency, but also may be the last set of bulbs you’ll ever buy. While incandescent bulbs typically burn out after 10,0000 to 15,000 hours, most, if not all the 921 RV LED options on this list burn for 35,000 hours or more.

Difference between 912 and 921 LED Bulbs

First, they’re both LED bulbs, but 921 RV Led bulbs are easier to get your hands on than 912 LED bulbs. Further, 921 bulbs offer a choice between filament and LED’s, whereas you only have an LED option with 912 bulbs.

921 RV replacement LED bulbs also offer better energy efficiency compared to 912 LED bulbs, and use the same plug design, so you can use them in your existing and older light fixtures.

How To Install 921 Led Bulbs in Your RV?

If you’re making the switch to 921 LED bulbs in your RV, then the installation process is literally a no-brainer, so you won’t have to bring in professional help. You will need some tools though such as a chair or a step ladder depending on where you’re going to install the bulbs.

The first most important thing to do before you install the 921 LED bulb is to turn off the light switch or better off switch off the main circuit breaker of the RV. If there was an existing bulb in the socket, you should let it cool off first before touching and removing it.

Get started by removing the cover/diffuser to access the bulb, or remove the screws of the dome. Remove the old bulb by twisting it off, while pushing it in slightly, and then pull it off. Install the RV 921 LED bulbs by performing the aforementioned process in reverse order, and voila — your RV is ready to glow with the new bright lights.
