Dimensions of Optronics LED Strip Light

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 370 raw lumen capacity and produces 342 effective lumens.

Average Customer Rating:  4.8 out of 5 stars   (26 Customer Reviews)

15-3/4" long x 1" wide x 5/8" thick. Low-profile LED strip light produces bright white light for an interior area. Durable polycarbonate housing and lens. Surface mount - hardware not included. 2-Wire design. 18 Diodes.


Good product fairly priced. Works like a charm where I needed extra light.


Nice, bright strip lights. I'd give these a four and a half Stars actually, only because the plastic housing seems a little weak. Being in a tool trailer I'm concerned they are going to be hit and perhaps break in half. Aside from that they appear to be well built and of course are very bright

Been a year and all LEDs are still functioning and bright. Ive recommended these lights several times because of their low profile and bright output.
Joseph C - 12/29/2020


Works very good. I had to add a switch for it. My bad, but the light is fine


Used it for the in cab ceiling light on my 87' chevy pickup
cause that year cab light was mounted under dash. 40 watts of led
strip is very awesome!!!


Hi, We put these on a Firetruck and each light has a diodes out already, we will be replacing them soon with another style light.

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

I bought these for my snowmobile trailer. I love the low profile the ones that come with the trailers are cheap and stick out.
I bought 3 of them. They are very bright.


This light works great! Works perfect over the horses' heads in my trailer.


Well it's been a year now since we installed 3 of these in our new cargo tool trailer and I must say they have been outstanding! Plenty of light from just one of these but with 3 in an 18' trailer it's like bright daylight inside. I'd like to say these are rugged and durable, but I can't attest to it since they were mounted on the roof supports of the 7' 6" interior of our trailer and they just don't get any abuse up there. Having said that, the frames and lenses seemed to be of good quality and robust enough to likely take at least a bit of punishment. I've had other LED lights - mostly on the exterior of a trailer - that would lose one or more of the diodes after a few short months. But these lights get quite a bit of use and after a year are all still shining brightly!
In a time where more and more "good" products seem to be moving to (let's just say) offshore production and subsequently becoming a "not-so-good" product, it's good to know there are still companies that care about making a quality product.


The lights work great in lighting up my 30-foot enclosed car trailer. Bright lights and low consumption. I run them off the on-board 12v battery which gets charged when parked. The only confusion is the color of the electrical leads on the lights. White is negative and black is positive. It would be better to have red as the positive.


The strip light is just right for my need. It was easy to install even though the location was awkward to reach. Good product. Excellent service.

Still working great!
Wendell S - 01/06/2020


My motor home's bathroom had poor factory lighting even with LED bulb upgrade. I installed the Optronics LED light and what a difference. Now I'm considering other locations in the MY.


this is a great replacement light for my trailer fluorescent light which is over $100 to replace. checked with 9 volt battery and it is nice and bright. will have to wire in a switch since there is none on the light.led's are real power savers .


LED lights work perfectly in my 30' car trailer. I power them from the rechargeable 12v battery that I use for emergency braking.




Excellent customer service. Product performed as described in video and was easy to install Shipping was lighting fast.


Great light output and looks modern. I bought something like this from IKEA for my kitchen and these put out more light, worth it defiantly.


Always had good experience when buying items from etrailer


Great product. Provides excellent coverage within trailer. Also easy installation.


High quality products and affordable.


easy to install and good lighting. Received fast too.


Great light, was shipped fast!


Arrived quickly! Thank you!


this lite is a power house of light for its small size.couldn't ask for anything better.


Just what I wanted they will work great

  • How do the Optronics LED Light Strip # ILL71CB Compare to a Fluorescent Light
    The effective lumens rating for the Optronics LED Thinline Interior Lights, # ILL71CB, is 342 lumens. It is difficult to compare the lumens output of this LED light strip to a 2 tube fluorescent light without knowing the length and wattage of the fluorescent bulbs. After doing some research, it seems that many 16 inch fluorescent bulbs are 16-watts and these bulbs have a lumens output of 1000. With this information, we could say that a 2 bulb fluorescent light that has two 16 inch, 16-watt...

    Interior LED trailer light # ILL71CB is going to be good and bright option and is designed to withstand very cold temperatures. To get a good amount of light in a 16 foot long trailer I recommend using at least 2 of this or any light. It is better to have more than enough light than not enough.

  • Attaching LED Strip Light To Dome Light In Enclosed Trailer
    If the light you choose is a 2-wire design like the Thinline Opti-Brite LED Interior Strip Light, part # ILL71CB, you will have a White wire and a Black wire. The Black wire would be attached to your 12-Volt power source, and the White wire needs to be grounded to a clean metal surface. To be able to use this light and have it controlled by the dome light you will need to attach the Black wire to the wire between the dome light switch and the dome light.

  • Wiring Two Opti-Brite LED Interior Strip Lights ILL71CB to Trailer Wiring Switch
    The Opti-Brite LED Interior Strip Light part # ILL71CB that you referenced would install like you mentioned. The black wire would go to the power wire you have for the current light and then the white to the ground you mentioned as well. Basically the power wire of both lights would run to the wire you currently have which is operated by the switch you mentioned having.

  • Would Optronics Thinline Opti-Brite Interior Strip Light Work As Lighting For a Trailer Workbench
    I believe I have the perfect solution to light your workbench! Check out the Optronics Thinline Opti-Brite LED Interior Strip Light # ILL72CB. This light measures 21-7/8 long x 1 wide x 5/8 thick inches. It has 5/32 inch mounting holes on 21-9/32 inch centers. This light has 27 diodes and puts out 513 effective lumens. This is a 12 volt, hard-wire light that has a 4 inch lead and ground wire exiting out the back in the center. You would need only four lights to cover your entire work...

  • Recommended Opti-Brite 16" LED Strip Light
    We do offer the Opti-Brite LED Interior Strip Light # ILL71CB which is our only 16" LED strip light, but it is not the exact same as the Opti-Brite LED Strip Light for RVs # ILL77CBB you were looking at. The key difference that it does not have the 45 degree wedge base that angles downward. Besides that they are both rated for interior and exterior use, are both water proof, and will both work with 12v Power systems. I included a video of the Opti-Brite # ILL71CB for you to take a look at.

  • Interior LED Trailer Light with Switch for 10 Foot Long Clamshell Snowmobile Trailer
    We have exactly what you are looking for. I recommend part # RVILL39. This is an oval interior surface mount light that has 9 LED lights and also features an on/off switch. With the included snap-on bezel this light measures 7.188 X 5.188 X 1.438 inches. The light output for this light is 230 lumens which should give you plenty of light in your trailer.

  • Troubleshooting Interior Lights Not Functioning on an Enclosed Trailer
    The interior lights of your trailer would be powered by the 12 volt accessory circuit on the 7-way of your 2004 Chevy 2500. This would be the pin in the 2:00 position. You can use a circuit tester like part # PTW2993 to test that pin to see if it is active. Most likely that circuit hasn't been activated under the hood of your truck, or the fuse/relay for that circuit is blown. Check out the help article that I attached that has a section in it about activating this circuit.

  • Recommended Interior and Exterior LED Lighting for Enclosed Box Trailer
    We've got the lighting items you need for your high school band's instrument trailer. I strongly recommend you opt for LED-type lights, rather than standard incandescent bulb lights. There are several advantages to using LED lights. LEDs use only about 1/10th the power required by incandescent lights. Their efficiency also means less waste heat, which can matter a lot in warm weather when the sun has already heated up the trailer interior. They also do not change color with age the way...
