Optronics RVILL34 LED Interior RV Light Dimensions

Raw Lumens vs. Effective Lumens

Lumens are used to measure the amount of usable light that is put out by a light source. Raw lumens represent the number of lumens that the manufacturer claims the LEDs are capable of producing. It does not include the light's drive method or the amount of light lost from the lens or reflector. Effective lumens take these factors into account and represent the number of lumens that are actually produced by the complete light assembly, not just the amount of light that the diodes are capable of producing. This light has a 920 raw lumen capacity and produces 815 effective lumens.

I am well pleased with LED light upgrade. They are bright and are very easy to install. they are great buy.


Very nice product for a very low price. I think these are the best buy in trailer lights. They're good enough that I cancelled my plans to install a couple of 4ft strip lights. Brightness - very good, a pair fully and easily light up the interior of my 8.5x20 enclosed trailer. It helps that I have gloss white walls and ceiling. For a trailer with a plywood interior, I would probably go with 3 of these on the ceiling. If you need detailed task lighting, you might consider using 4 of these (two at the ends of the trailer and two spaced out between front and back). That would give an enormous amount of light thruout the interior. Installation: very easy. The covers come off easily if you use a blunt tool and push on the cover "slots" to ease the lens off. I used the blunt handle of a trim removal tool, but a piece of wood dowl would work fine as well, Even a screwdriver might be fine if you were really careful with it. The lenses are on tight but apply firm pressure an the lens will slide loose. The lights have 8 mounting holes but you really only need to use 4. This makes it easy because you just pick the holes that are most convenient to use (I put a pair into the aluminum header rail in my trailer ceiling). Don't forget that white is ground and black is power. I grounded the lights by crimping a small ring terminal on the white lead and putting it over one of the mounting screws.

I compared these with the lights in many other trailers and no question these are the best value in trailer interior lighting. There are better lights but at more than 5x the price. Quite a few friends who saw these in my trailer have bought these to replace their existing lights.

I changed out 7 double and 5 single lights to these LED lights in our 2009 Wildwood Bunkhouse. They are excellent lights and nicely brighter than the originals (many of which were beginning to melt the lenses). I noted in the reviews of the trouble getting the lenses off for mounting. I had all 19 lenses off in less than 5 minutes. Very simple. Just used a small wooden dowel (diameter of a pencil) with the end shapped square and placed in the small notch in the lense and gave a firm tap with a small hammer. Tap one side then the other and they are off. I rigged up a stop for the light on the camper table but could have used a shallow drawer or some such.

Lights have worked out great. The battery power supply fan never turns of now, but did originally when about 4 old lights were on. I am thinking of replacing the last two, that I thought last year would not be used much.

I put four of these in a 14' trailer. They are bright! I really only need two. The clam-shells are tricky to remove until you learn to squeeze them, and then the pop right off. Highly recommended.


This has been a great replacement for art pop up. Very easy to replace the original one. Thanks

Great. Still working fine.
Kevin - 05/17/2022


This LED light corrected the problem that I had with OEM lights in my 2014 travel trailer where RFI from the lights were causing interference on broadcast television. Of course I have other lights that need replacement, but this is a solution. Attached photo is for the single head light which also had the same problem.

problem solved
David W - 11/10/2019

Still pleased with this light.
David - 12/29/2019


The factory lights didn't last 3 months in my pioneer travel trailer. I replaced them all with this light. All but 1 that continued to work...until I installed the others. As soon a I finished the last one died too. Excellent light. Easy to install and brighter than factory. etrailer is excellent as always. Makes all others look bad


Bright, but zero resistance to moisture. Trailer got humid and they went out one by one

I will have our Customer Service team reach out to you. The lights do have a limited lifetime warranty.

Easy to install and provides great light. My wife loves it. Fast shipping and great communications from George. Will continue to purchase items from

We bought a different, used trailer since this review, and it was very dark inside with the old lights. I replaced all the lights with these LEDs and it changed everything. I highly recommend this light, especially if your trailer is dark and gloomy.

The best led lights ever. Very bright, great for reading, doing puzzles, or whatever. Not the same size as your original, I bought some plastic plugs from Hobby Lobby to fill holes that exposed on my ceiling. Looks good. Easy installation snip 2 wires, scotch clip the the white @ black wires, turn on the power. Perfection

Installed in a Windjammer front closet to replace a single fixture with failing switch and the extra light plus positive switch is a great improvement.


The interior LED light was the exact light I was looking for at a great price. Thank you etrailer!

Light was a perfect match in our RV bathroom and it works great!
Stan - 12/09/2021


Works great has plenty of light.


I love it! It's better than the original light & completely covers the spot it was in. The technician had a little trouble removing the plastic cover to access the screw holes, but once that was accomplished, it was a quick installation.


As advertised. Perfect for inside our work trailer. Easy to install.


These things are awesome !!! Installed 2 of these in my 12 ft. cargo trailer. It's like daylight in there now! I liked them so much I'm ordering 7 more for my camper. If you haven't made the switch to LED lighting, it's time. They put out a lot better light, generate less heat, and use less power. I think they are well worth the money.


This is a nice dome light for a travel trailer. Once I got the lenses off installation was pretty simple, 8 screws (not included) and drill a hole for the wires. My only problem was that the lenses are real difficult to remove and replace. I was actually afraid I would break the lenses before I finally got them to release. I think that once the light is installed you will never have to remove the lenses again.


These fixtures were an exact replacement for the previous incandescent fixtures in the RV so they use the same screws and screw holes. I replaced 8 fixtures. The hardest part of the installation was removal of the lens on the new fixtures. The old lens slid off without effort but I resorted to using the blade of a butter knife to carefully pry the new lenses off. The increased brightness level of the new LED fixture is a wonderful change in the RV.


The product seems to be ok but the packaging was awful. I bought 12 double lights and 2 single. All of the lights had no covering and were thrown into the shipping box without any concern for transport damage. Thankfully there was no damage but it was obvious that the person who packed this box was not taking any pride in their job. I had to further transport the lights to a distant location and using the wadded up packing paper I was able to layer the lights using the shipping paper to separate the layers and support the lights so they would not be damaged.There was a right way to do it and it only took a little bit of time to reduce the chance that the light could be damaged. Keep in mind that I am doing everything I can to avoid [online vendor]. This kind of service is not helping


Well nice light, much brighter, and it also lists it as a Custom Fit for the 2010 Keystone Energy TT Toy Hauler and is an LED, but you will find the lights that came in that trailer are much wider than this model. You will have to move the light over to cover the front holes and kind of press the roof material back over and have a few holes on the back side. I touched them up some with a paint pen and will have to find something to patch them with.


I installed these lights right away. They replaced a more blue LED lighting system in our camper. Love the warm color and couldn’t help but show our friends how nice the light was in the camper.

Continue to enjoy the lights and the warm color of the light.
George - 09/24/2021


I installed these lights every 4 feet in my new enclosed car hauler and boy to they light things up! With no windows in the trailer and the door closed it's completely dark in there and the one tiny light supplied with the trailer was not going to do it.

Lights work great. I installed a master switch right by the door and when I enter I can light up the entire trailer. A million times better than the single light that came with the trailer.
DrPcFix - 06/11/2020


They are as advertised. Inexpensive both in price and manufacture. For their application (solar powered shed lights) they are perfect.


Had a small problem with one of the lights they sent me was corrected immediately and a new light was shipped out. You can ask for better customer service than that

George - 01/06/2022


These lights are a PERFECT fit and replacement for the incandescent ones that were original in the trailer. I can use the original screws and screw holes when doing the upgrade!
