Recently, I purchased a Jayco RV. One of the reasons I chose a new coach and this particular make/model were the numerous standard features that are not included on other entry-level RV models. However, I was disappointed to find that Jayco used incandescent light bulbs throughout the interior.
Why did they use technology from 1880 when the alternative uses 90% less power, generates less heat, last much longer, and is now very affordable?
Here is how I went about upgrading the interior RV light bulbs to LED lighting
Indentify the Fixture Type and Size
Best thing to do is to remove one of the bulbs and take a look. Our RV had T10 wedge sockets (for most of the lights).
Don’t forget the light in the cab and in the fridge. The fridge required a Festoon base and I didn’t do the cab lights yet. I did replace the dome and maps lights in my car and they require the Festoon style as well.
When purchasing a Festoon style LED it is important to check the size you will need before ordering. For my RV fridge I used a 42mm LED and for the car a 31mm.
Count the Number of Bulbs to Replace
When counting the number of bulbs in the RV it is important not to forget some that are hidden. Lights may be in storage compartments, bathrooms, on the exterior, and in the refrigerator.
Choose a Brightness
LEDs will have a lumen rating. I found that the 288 lumen models were good replacements for the old bulbs. However, the higher lumen models can be more expensive than low lumen units. So, I mixed it up and used 100 lumen lighting under cabinets and in storage areas where I didn’t need the bright lights. It worked out great and saved me a lot of money.
Choose a Light Color
This is where I messed up.
The higher lumen LEDs were available in both Cool and Warm style. I didn’t think much about the difference and ordered the Cool-White style. They worked great and looked good (in my opinion). My wife didn’t agree. So, I then purchased a couple Warm-White models and back to happy life.
The Cool-White is shown in the photo on the right. It looks very white.
The Warm-White is on the left and looks more yellow and closer to the previous incandescent bulbs.
Find a Place to Purchase
Retail stores are usually very expensive for these type of parts so I like to shop online. Luckily, I have a family member who is in the LED light business. He has great prices on the parts I needed and super fast shipping. The website I used is WiredCo.com
