Video Transcript for Optronics Trailer Lights ILL39CB Review

Today we're going to be taking a look at part number ILL39CB. This is the Optronics LED Dome Light. It's going to contain 39 diodes. The LEDs are great system to have, they're going to be a great replacement for incandescent bulbs. They don't require hardly any maintenance at all. The LEDs also conserve power.

You don't have to worry about replacing the bulbs. You don't have to worry about the brittle filaments. This is an ultra bright flange mount and design. It's going to feature a clear lens, it's going to allow a lot of lights to come through. It's going to distribute the light evenly. Now, this is designed for heavy duty applications.

It's got a polycarbonate, sealed housing. Back here, it's got a nice sealant over the back part. It's going to seal everything that you see back here. Allowing the power wire and your ground wire to come through. These are going to be 16 gauge wires and they got a nice protective casing that goes around them.

That's just going to protect the wires. Going over the overall measurements real quick, it's going to give us an overall diameter of 7 inches. That is measuring edge to edge including the flange. Not including the flange it's going to be about 6 inches. That's just the actual light portion, that are again, it contains 39 diodes. It's going to have three mount locations.

We have one here, one here and one hear. The distance between the mount holes, center on center, is going to be 5 1/2 inches. That's going to be the same distance between each mounting location. It's a really nice thin light as well. It's only about a half inch in thickness. We want to go and connect it to our external power source, that way you can see what it looks like with power running to it. Then we'll also be able to turn off our overhead lights, that way you can see it in a low light setting. Just going to get our wires connected. You can see here that the 39 diodes are going to distribute a lot of light. The clear lens allows a lot of the white lights to come through. It's going to distribute it evenly. It's sending out a nice consistent, strong LED signal. That's going to do it for today's review of part number ILL39CB. This is the Optronics LED Dome Light. .

Took a gamble on this light to replace the 5-led gig light over the vanity in our Cedar Creek Cottage RV. We couldn't be more pleased with the additional white light it affords us. A pleasure to deal with etrailer.com and I'll keep them in mind for future RV-related purchases. ?????? 325262

The product was just as shown and listed. We actually used it to replace an older, larger light over our dining table in our motor home. The other light was outdated, and hung down over the table, so it drew attention to how outdated it was. This light mounted flush with the ceiling, gives out more light than the old one, and looks ten times better. Also, it still works with the dimming feature that is build into the switch, so we didn't even lose that function. Installation was really easy. I would recommend it with no reservations. 250561

Definitely worth the money. More than enough light in the trailer now. 316973

I replaced the lamp in my trailer because the lamp that came with it was quite dim. This light is bright enough to find my tools in the darkest corners! 283861

I got this installed in my Little Debbie truck and the light it puts off is outstanding. I will be buying another one for the front of my truck. 315037
