Optronics ILL08 Series Opti-Brite LED Dome 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 1,400 raw lumen capacity and produces 990 effective lumens.

This light was the perfect choice for the ceiling in my enclosed car hauler. It is very bright. I used 3 on the ceiling of a 24' trailer. The only way it could be better is if it was a surface mounted light. The people at are great to work with and know their products. Thanks Kim P


Arrived promptly as ordered. 100% satisfied with each and every item that I've ordered from etrailer . I would recommend etrailer with confidence.


Mounted 2 in 24' boxtruck. Works great. Just centered two running the long way. Could use a third if u planned to work inside with roll-up door closed. 6 would be amazing but I'm very happy with two. Appear to be good quality. The joists on the ceiling of our truck are 22.5" center to center so I made small sheet metal extensions to make them longer but they work fine just a little fabrication. Went through a few cheaper options but returned them all. These actually light the box up very well and good spread of light either parralel with truck or horizontally mounted. I mounted them the long way for ease but didn't seem to make much difference in the lighting either way.


This classy looking light is very bright, and I like it a lot. I would have given it an excellent rating except for a few issues, which I was aware of when I purchased the light. The first is the lack of a built in on-off switch. My old surface mount Liteco 179 (made by the same company, but discontinued) had a small built in switch that I mounted on this unit. I had to cut into the flange to do it, and it fits, but not perfect-plus it's a cream color, not white. The second is the lack of hardware. I mean, how much can a few white screws cost? The third would be the lack of a surface mount option. You could surface mount it using longer screws, which along with the 3/4 inch gap, would be very unappealing. I think a surface mount version of this unit would be a nice option. I had to cut the fiber board above my sink, and also cut 3/4" into a portion of a cross beam that supports the cabinet. I'm sure my cat and I will be eating saw dust for the next six months. That being said, now that the job is done, it looks very nice, and gives off much more light than my old florescent fixture. I like that. I like it a lot.

This fixture continues to be the best and brightest LED I have in my RV. As stated in my initial review, it would be perfect if it incorporated an onoff switch, and there was a way to surface mount it. Its worth the price in replacement florescent bulbs alone. Im still very pleased.

I installed 5 light in a new 2020, utility trailer 4000dx
Just do we could have a place to dine n dance in between freight loads
I love these lights so I bought another trailer and more lights just to perfect the install and enjoy the trailer


I replaced the current lights in my 20FT box truck with these lights and they work Great!


Great product


Very brite just what I need


Great bright light works great in my trailer


Go them quick and easy no hassle.


We have been using these lights for our truck boxes and the drivers are very happy with them. When they do late night pick up or deliveries they say it lights up the inside of the box so much more then the spot lights we had been using. We have now moved to installing these lights into our road trailers. I have no problem with recommending these lights, they have a low profile and low voltage draw do to being LED lights. This is a good product for it's price.


I own a bread truck instead 3 of these lights in the rear of the truck about a year ago. They work absolutely amazing they are way brighter than I thought they would be and my guys love how they light up the entire back of the truck. Absolutely worth every penny!


We love the lights , our customers love them too


I am using this light for the interior of my band trailer. It lights up the neighborhood! Money well spent after wasting time and money on smaller, battery powered lighting that always fell apart from road vibrations.


I installed two of these lights inside my KUV van. My van is the high top and allows me to walk in without hitting my head. Two of these lights illuminate the interior excellent. I highly recommend these lights for your KUV.


We just got this light for our cargo van and its several magnitudes brighter than the Maxxima LED dome lights we currently have. The light is very white and the product was exactly as described.


Expensive but very nice lights. I used 3 of them to light a tall height, 24' enclosed trailer and they worked perfect. The inside of the trailer is now like a bright sunny day!


I can only rate my experience with the sales staff. I dealt with several and they were all eager to help. I run a NOP Animal Rescue and we are transforming a bus, and with etrailers help, I’ll get it done perfectly.


This light was easy to install in the back of a 16 ft box truck. It turns the night into day. Very bright!! love it


Works as advertised. Puts out a lot of light!


easy to install, perfect for what I need, like daylight in the box of the truck, Thank You!!


Exactly what I was looking for my trailer. Installed two and it made an unbelievable difference.


Very nice lights. Worked well for enclosed trailer


I've ordered these from etrailer before and they are a great product


Great product and super fast shipping. Would highly recommend to anyone looking for a great 12v interior light.
