Optronics ILL24 Series LED 6 Inch Dome Light Dimensions

Need extra light over your RV kitchen sink for when you do the dishes? Or perhaps you need to upgrade the dim, old lights in your travel trailer? This dome light has cool white LEDs that give you brighter light underneath a kitchen cabinet, in a walkway, in a closet, or inside your enclosed trailer. And the sealed, polycarbonate housing and lens are waterproof so water won't leak in and damage the LEDs.


Optronics Dome Light LEDs

LEDs are more energy efficient, last longer, and burn brighter than lights with incandescent bulbs. You won't have to worry about replacing bulbs that have brittle filaments. And because LEDs draw minimal power, the light won't drain your battery, overload your circuits, or produce too much heat.


Raw Lumens vs. Effective Lumens


Optronics Dome Light Lumens

Lumens are utilized to measure the actual amount of light that you can see and use from a light source. If you need a super bright light for a workspace, you will want to go with a light that has a higher lumen count. If you want a softer glow in an RV living space, you should go with a light that has a lower lumen count.


Light sources typically have 2 different kinds of lumens: raw and effective. Raw lumens represent the natural amount of light that a manufacturer says their light fixtures can produce. Effective lumens, on the other hand, represent the usable brightness of the entire light assembly, including the drive method or any lenses or reflectors.


Surface-Mount, Bolt-On Installation is Easy


Optronics Dome Light Installed

This surface-mount dome light is incredibly easy to install as an upgrade or direct replacement of your existing light. Using the built-in bolt holes on the housing and the hardware (not included), bolt the housing onto the ceiling, wall, or cabinet. The light wires to a switch inside your RV and hooks up to ground (white wire) and power (black wire).

I bought two of these lights to replace the ones in my cargo trailer. And got three lights with the battery in the trailer. Very bright and do a great job lighting the trailer up. The customer service from etrailer was some of the best I've ever seen. I would recommend them to anyone looking for parts.



by:

I searched so many places trying to find the exact light or close to it. Found it on your site, fits perfectly and chrome trim snapped back on light. Old light burnt out right out of warranty. 2016 north woods camper, exterior led light. I’ll start my searches on your site going forward. Thanks



by:

It's a good light, but 3 wasn't going to do the job in our head to head horse trailer that we are restoring, so we are going to get 3 more for a total of 6 in an area of 7x22. Don't get me wrong, 3 would do the job for most, but dealing with hoses I'd rather have to much light then not enough. I added a photo of the "test" we did, instead of being center mounted we are going add a light on other side of center.



by:

Good light... We already bought 3, but had to go 3 more for more light, well to us, better light. Submitted photo of out head to head horse trailer we are rebuilding (lights just setup for testing), the inside area is about 7x22 (I believe my other photo is one review down).



by:

So far so good! I just ran the wires and turned them on and could not be happier with the amount of light. We put 8 lights in and 8'x16' enclosed trailer and we probably could have got away with 6 of them.



by:

Very bright light but with no glare, very good product



by:

Attached are some photos the trailer is still a work in progress but the lights are a big help



by:

I bought the LED lights as a Christmas gift for my son for his trailer. He hooked them up and now it's daylight in his trailer. It has made his workdays much brighter (pun intended). They are more impressive than I anticipated and he is thrilled.

The lights remain the best I have seen in any trailer. We have had no problems with them and they make the trailer bright as day. Thanks for caring how your product works.



by:

Product is as described and very easy to install. Installed them on a enclosed trailer for additional lighting. The trailer is used for all my kite, surf, snowboard gear, and camping. The lumens and throw of the light are incredible. Great product and highly recommended.



by:

My etrailer buying experience was perfect. I installed six of these lights in the ceiling of my 14 ft cargo trailer. They light it up completely with no shadows. Etrailer had the lights in stock, shipped them immediately and much to my delight, they upgraded my shipping selection free of charge. In a time when customer service sometimes takes a back seat, etrailer really came through. Thank you and I look forward to my next order.



by:

We have purchased many of these last the past year and find them to be of great quality. Opti-brite Round Led Dome Light - 21 Diodes.



by:

Because there is a video of almost every product etrailer sells I can make an informed decision every time I purchase a product. No other site I'm aware of offers this - I think it's fantastic. etrailer is now my go to source for replacement and upgrade parts for my trailer. Thank you etrailer for developing and maintaining an extraordinary online shopping experience



by:

Love the lights have put them in multiple enclosed trailers to have great lighting inside them.



by:

I had ordered a replacement light for my employers trailer and so when it came time to put lights in my own trailer I knew exactly where to get them from. Great product!!



by:

This LED Light is a great light, nice and bright. Flush mounting worked great for us.



by:

Replace the lights in my enclosed trailer with these. worked great.



by:

Very bright - Bought 5 and installed them on the ceiling of a 7' x 16' enclosed trailer. I am very pleased with them.



by:

great lighting , no problems with the install or operation of these lights. I would recommend these lights



by:

For this price - the expectation is that this interior light (for enclosed trailer) will last essentially forever. Easy mount. Easy connect..



by:

Easy install, much brighter than original 8 diode installation; seems to meet all expectations. I had them installed 15 minutes after I received them, no brainer!



by:

Excellent product. Improves the quality of the light in our trailers for our drivers. Have had very good feedback from them how much it improves the lighting.



by:

This is a great product; easy to install, and illuminates as described. Delivered as promised. I liked this light so much, I just ordered 3 more.



by:

Great improvement over the incandescent lighting that was in my enclosed trailer.



by:

Well worth the money. Very bright uniform light in flat surface mount package (although I covered up a hole/recessed style).



by:

Great service. The 12 volt LED lights are excellent.

  • Recommended Interior Light for Horse Trailer
    I recommend the Peterson Interior and Compartment Light, part # 433600. If strategically mounted in your horse trailer it should provide you with plenty of light. If your trailer has a 6- or 7-way trailer connector you would want to find the 12-volt accessory wire that is on the connector and use that as the power source for part # 433600. Typically, this wire will be black and will have 12 volts of power present at the connector if your tow vehicle is turned on or not. The light comes...

  • Comparing Optronics LED Dome Lights ILL24CB and ILL39CB for Use in Ice House
    Both of the Optronics LED dome lights you referenced, 24-diode # ILL24CB and 39-diode # ILL39CB, feature sealed water-resistant housings, a lifetime warranty on their LEDs and superior electrical efficiency - using about one-tenth the power of standard incandescent lights. The advantages of the # ILL39CB are that it can work in both 12V and 24V systems and that it includes a built-in low voltage cut-off (when the battery's output drops to 11 volts) to prevent battery drain. Unless you...

    For LED Domed Utility/Multipurpose Light # ILL24CB there are 2 lumen ratings. One is the raw lumen output which is the rating in perfect conditions. For this light the raw lumen output is 585 lumen. The effective lumen output is the average condition rating; so what you can count on this light producing. The effective lumen output for this light is 453 lumen. For the Opti-Brite LED Interior Light # ILL08COB, the raw lumen output rating is 1400 lumen. The effective lumen output rating...

  • Adding 4 LED Dome Lights Causes 20 Amp Fuse to Blow In Truck
    Even using 4 of LED light # ILL24CB would only produce about 1/2 of 1 amp. The fact that the 4th light is causing fuses to blow indicates to me that there is likely a short. Although it is weird that it doesn't blow the 15 amp fuse (unless the 15 amp is a slow-blow fuse). I would go with the smallest fuse you can get that is greater than 0.5 amps. Check the wiring where the 4th light is installed including the ground and make sure there are no pinched or frayed wires touching bare metal...

  • Interior 12 Volt LED Light Recommendation for a 7 x 14 Foot Enclosed Trailer
    The LED RV Interior Light, # ILL31CB, runs off of a 12 volt DC system. It actually draws 0.107 amps at 12.8 volts. It will not work on a 110 volt AC system. This light is a surface mount light meaning the light will not be flush with the wall or ceiling once installed, it will stick out some. But part of the light from the mounting surface will need to be recessed into the wall. I would do at least 2 rows of 3 running the length of the trailer. A better option for a true surface mount...

  • Is Optronics Ultra-Thin 11 Diode LED Utility Light, Part # BUL69CB, Bright Enough for Utility Use?
    The Optronics Ultra-Thin 11 Diode LED Utility Light, Part # BUL69CB, is intended for use as a general purpose trailer utility light. Typically most clearance/marker light assemblies are amber in color and only use between 2 and 6 diodes; this utility light uses 11 diodes. Its sealed and waterproof 1-piece compact housing makes it ideal for use on the exterior of your horse trailer. LED-type lights use only a small fraction of the power required by incandescent bulbs, and this unit draws...

  • Interior LED Lights for a 7 x 22 Foot Area in an Enclosed Horse Trailer
    Six of the RV LED interior light # ILL31CB should provide adequate light for your trailer. More so than the incandescent bulbs in # 30-76-243. What I recommend though is to go with the LED 24 diode light # ILL24CB. The additional diodes will provide even more light than the 10 diodes in the light you referenced. I have linked a video review for you. The other option is to go with an LED flood light like # TLL48FB which has a 1200 lumen rating which would be like a vehicles headlights...

  • Voltage Required and Light Output of Optronics LED Domed Utility Light # ILL24CB
    The Optronics LED Domed Utility/Multipurpose Light you referenced, part # ILL24CB draws 0.120 amps at 12.8 volts. The lamp is designed for a 12-volt electrical system. This lamp has a light output of 76 Candela, which is equal to Lumens at a 1 foot distance.

  • Bright Interior Lights for a 20 Foot Enclosed Snowmobile Trailer
    For a 20 foot trailer, I would definitely go with multiple units of whatever light you choose. The LED light you referenced, # ILL24CB, would be a good choice if you are using more than one. A diode count of 24 combined with the white light and clear lens will be bright, but not 20-foot-trailer bright for a single light. I would do at least 4 spaced evenly apart, one for each snowmobile position in the trailer.

  • Can 2 LED Domed Utility/Multipurpose Lights Light Up a 24 Foot Box Truck
    The utility light # ILL24CB has 36 diodes so it will be on the bright side. Two of them will probably provide a decent amount of light but 3 would be better especially if light is essential. Attaching the lights to the ceiling using a high grade automotive type of double-sided tape would suffice. What I recommend is to use self-taping screws, like # 101131802, so you will not have to drill and then just seal the holes with a sealant like # 0160297. It would be best to attach screws to...

  • Bright Interior Light Recommendation for Interior of Box Truck
    My favorite interior light that I would recommend for you is the part # ILL08COB. This light is super bright and since it uses LEDs instead of incandescent bulbs it hardly draws any amperage as well. I attached a review video for you to check out as well.

  • Recommended Interior LED Lights for 24-Foot Car Hauler Trailer
    For a 24-foot enclosed car hauler trailer I recommend at least three lights on the ceiling and possibly also one or two on the trailer's side walls to give you some illumination of the car's interior and to help when you're securing it in the trailer. Optronics part # RVILL34 is an 18-LED oval surface-mount light that includes a switch, a nice feature if you'd like to be able to control the lights individually. For a large (6-inch) round light without switching you can use domed light...

  • Does the LED Domed Utility/Multipurpose Light # ILL24CB Have a Switch
    The LED Domed Utility/Multipurpose Light, # ILL24CB, does not have a built-in on/off switch. You could wire a switch in-line with the dome lights wiring using # BL0108-00. Or you can use an incandescent light that has a built-in switch like # 390S.

  • Number of Diodes on the Domed Utility Light ILL24CB
    I pulled one of the Multipurpose Utility Light, part # ILL24CB from the warehouse and manually counted the diodes. There are a total of 36 diodes in the light in three rings, one of 18, one of 12 and one of 6.

  • Interior LED Light Recommendation for an Enclosed 5 x 12 Foot V-Nose Trailer
    I would say that you would need a minimum of 6 of the Thinline Sealed LED Utility Light, # UCL65CB, to light up the inside of your enclosed trailer. Another option would be the LED Domed Utility Light, # ILL24CB. Two or three of these should provide sufficient lighting for your trailer. You would also need to wire them together, and run them to a switch, like # BL0108-00.

  • Which Optronics Utility Light is Brighter Between the # ILL24CB and the # ILL22CB
    The Optronics # ILL24CB is going to be brighter than the Optronics # ILL22CB. In the videos and photos they are of the lights installed on different trailers and mounting locations so yes, it is very hard to tell. The # ILL22CB is also being demonstrated in an all white trailer with the interior of the installation bay's lights on, which white carries light so this could explain why it appears brighter. We are limited to installation videos on customer requests so while they are not...
