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 643 raw lumen capacity and produces 354 effective lumens.

Average Customer Rating:  4.8 out of 5 stars   (171 Customer Reviews)

Compact dome light illuminates your trailer's interior with 634 raw lumens of cool white light. Durable polycarbonate lens and white trim. 6" Long, 16-gauge power lead and ground wire with tinned ends. Surface mount - hardware not included.


I installed 4 of these lights low on the wall to assist in lighting the tie down anchors and straps in my car hauler trailer. They are very bright and easy to mount with 4 screws. These 4 lights and the 3 ceiling lights that I purchased from work great in making an enclosed trailer very bright inside. The surface mount makes these lights AAA+.


The lite works excellant. It was the right size and shape as advertised and wired direct. Could not have asked for a better fit!!!! Goes along with the other five lites I put in the same trailer, one in the bathroom,one under each cabinet over the couches,one above the beds that drop down, and one under the kitchen cabinets over the sink area. LOVE them all!!!!


products were great, I love them
control was lacking. One light came to me not in a bubble wrap bag and was missing the bezel/beauty ring/ cover.
thought that should have been caught before sending. They are shipping it out in the next 24-48 hours then to wait for the mail to bring it again. disappointed a bit.
other than that, the lights are great, bright and easy to install.


Why at that price you can’t send screws?


Simple install and two of them light the full backend of my cargo trailer. cool white color is nice and to too obnoxious like the super white LED's


Very Nice, Fast shipping. I got 2 of them last year and my write up was the same. I also posted being LED that I will never have to replace them. Well this one I got only because I added 2 more feet to my Ice House and needed one more. Awesome light guys. Super fast shipping

After 1 year and countless hours and on and offs they are still very bright and working great. I would not hesitate to reccomend or buy again, but alas, they are LED so i probebly wont ever have to again.

I ordered 3 LED lights from etrailer a few months ago to change out some of the flourescent fixtures in my RV. Etrailer delivered them on time and they were easy to install and work so great I ordered 4 more. These 4 arrived promptly and I am looking forward to having great lighting throughout my RV.
I fully endorse buying from them.


I got what I ordered. I installed the unit. It works so I am a HAPPY CAMPER.

I have has no issues with your product. I will be buying more LED lights from you very soon
Douglas T - 06/02/2019


The lights work great. Hugh improvement over the old 12V dome lights that came in the trailer.


Great lights at a great price. They are very bright and the color is exactly what I wanted.


Quality products and fast shipping!


Good quality and very bright reading lights !


Bought lights for food trailer that feeds the homeless in South Florida. Your prices are great ( since we have to work on donations) Thanks. Looks like the trailer had a canopy, will be looking to you about that. Thanks again.

1 year later I'm still really happy with these lights. Super bright, low profile so they're out of the way.


Used these as replacement lights that cost $167 thru utilimaster. Had to drill a few holes but we’ll worth the savings. Thanks etrailer


These were a perfect replacement for the original lighting and installed easily


I installed one light in closet and another in existing fixture to utilize switch on fixture. Great product easy to install


website is easy to navigate and there are good descriptions and photos of the products offered. Good selection of products as well. This is probably my favorite way to order parts since I am in a rural area.


Use 2 of them IN my Ice Shack. Would not hesitate to buy again, but being its LED i probably wont have too. Very Bright.

After 1 year it is still gong strong and still very bright. would not hesitate to buy another
Bruce - 06/27/2019


This fixture gives off a lot of light. Very efficient. Looks nice too.


Great light replacement for the existing light in bedroom. Excellent price

Great products and even better service. ..


These are very bright and easy to install. They are a good value for the light output.


Arrived quickly and in excellent condition. Works just fine.

  • Interior RV Light Recommendation to Replace Liteco 179 Interior Light
    I looked up the dimensions of your Liteco 179 interior light and the closest thing we have to it would be the part # ILL06COB which will be 11 inches by 4 inches. Your current light is 19-1/2 inches by 6-1/2 inches so this would be a bit smaller but the LED lights of this kit would provide a great deal of lighting.

  • Could Two of Opti-Brite LED Dome Light # ILL06COB be Wired to One Circuit
    Yes, if you wanted to wire 2 of the Opti-Brite LED Dome Light # ILL06COB to one circuit you certainly could. Since this light is LED is draws a very low amount of amperage.

  • Why Does OptiBrite ILL06COB Not Match Wire Colors of Battery
    For the Opti-Brite LED Dome Light part # ILL06COB that you referenced the white wire is the ground and the black is power. RV interiors are typically wired with house interior wire colors and that is why the colors of your battery are different. Batteries like yours are wired more like automotive applications where the red is power and black is ground. The power draw of each of these lights is .48 amps. That would be fine to have four of these on 16 gauge wire as that would be less than...

  • Does Opti-Brite LED Dome Light # ILL06COB Come with a Switch
    You would need to wire a switch to the Opti-Brite LED Dome Light # ILL06COB that you referenced as it only has a power and ground wire.

  • Interior How Many Opti-Brite LED Dome Light # ILL06COB for Nose of Trailer
    Since the Opti-Brite LED Dome Light # ILL06COB is LED it will draw a very low amount of amperage when illuminated. Because of that it can easily be powered by your marine battery and all ran to one switch. For the nose of a trailer 4 of these would be adequate. I attached a picture that shows how bright 4 of these lights light up a trailer interior for you to check out as well.

    The Opti-Brite LED Dome Light w/ Chrome Plated Steel Base - 6-7/16" Round - 2 Diodes - Clear Lens, # ILL91CB, is able to be connected to the battery like you mentioned. Actually all of the lights will function if conneced in that way. This light only puts out 168 lumens or less than a 25 watt lightbulb. I've attached a video for you.

  • Which Opti-Brite LED Dome Light Comes with Ring to Cover Screw Holes
    The Opti-Brite LED Dome Light # ILL10CCB that you referenced does not have a plate or ring to cover the screw holes. The closest version of this light that does have this is the Opti-Brite LED Dome Light # ILL06COB which is smaller at 11 inches by 4 inches.

  • LED Horse Trailer Lighting Recommendations for Interior and Exterior
    In terms of brightness the part # ILL08COB is really hard to beat as it's going to be the brightest option we carry. We do have the part # ILL06COB which costs a bit less but is still relatively bright. About half as bright as the one you mentioned. For a bright LED flood light you'd then want the part # TLL50FB for the porch type lights you wanted to replace.

  • LED Light to Replace Stock RV Bathroom Light Fixture
    Opti-Brite LED Dome Light # ILL06COB will put out 643 raw lumens and 354 effective lumens, which equates to about a 40 watt incandescent light bulb. Depending on what you currently have, it most likely is more effective as it is one of the higher lumen ratings for an LED dome light. If you want to ensure a brighter space, you may consider the Optronics LED RV Interior Light with Switch # RVILL34 which will put out 920 lumens or 815 effective lumens. This is the equivalent of a 60 watt...

    For the interior LED light, you can use essentially any style that best suits your needs, such as the Opti-Brite LED Dome Light # ILL06COB. I have added a link below to our selection of interior LED lights as well. As for the solar panel, that really depends on your power needs, but if it's just for a battery controlling a light, something small will be fine, and I recommend the OptiMate Solar Charging System with Controller - 80 Watt Solar Panel # MA46JR. The # MA46JR is a single panel...

  • LED Dome Light 22 Inches Long x 7 Inches Wide
    The closest option we have to what you are looking for other than the # ILL10CCB you referenced is the LED RV Utility Light part # ILL06COB which measures 11" long x 4" wide. This light does however mount a little differently which you can see in the attached photo. We do not have have an LED dome light that is 22" long x 7" wide unfortunately.

  • How to Add a Battery to an Enclosed 6x12 Cargo Trailer for Powering Interior Lights.
    So the right way for you to do this will depend on how often you're going to use the lights and how many of them there are. If a trailer isn't equipped with a battery, the interior lighting is frequently tied into the running lamp circuit. Turn on the vehicle's running lights and boom, on come the lights. This is the simple way to go. You'd obviously need the truck there and plugged in to make that happen. You'd also want to run the truck from time to time so the alternator keeps the vehicle...

  • Simple Light Needed for Horse Trailer Tack Room
    The easiest thing to use/install is the NightMinder RV Task Light # NM-Motion-011. This is a battery powered light that uses 3 AAA batteries (not included). All you need to do is get rechargeable batteries to avoid purchasing batteries constantly. It would also be good to get at least 6 batteries so you can have some charging while the others are in use.
