Video Transcript for Diamond 906/921 LED Light Bulb Review

Hello neighbors. It's Brad here at etrailer and today we're taking a look at the Diamond LED bulbs. This is gonna be a replacement for a 9-0-6 or a 9-21 bulb. It's in 5,500 K. It's dinnertime in the camper. So let's get some lights on, and get ready to eat.

Of course, we have a bulb out. And that can happen over time. Your incandescent bulbs just kind of burn out. So, we'll go ahead and we're gonna replace that bulb, but why not upgrade it if you're already gonna change it out Let's take a look at a good option for that. Now, if you've been in camper or own one, it's very common to have these typical light fixtures in them.

And if you've never pulled them apart to get a burnt bulb out, I'll show you how to do that real quick. And it's simply going to slide down and then pop out. The bulb, just pull that out. And instead of putting another incandescent in, we're actually going to be putting this LED light in. And this is the new standard in light technology for multiple reasons.

Not only will it give us a nice, bright light, it's also way more efficient than our incandescent. It also is cooler as far as temperature once it's been on for awhile and especially in a camper, these are nice because they are vibration resistant. There's no filament to get knocked loose during bumps. So, really this bulb should last a long time. In fact, up to 50,000 hours.

Now enough specs, let's see how it looks. And immediately you notice the difference between the LED and the incandescent. To see these side by side really shows the difference between the two. The incandescent bulb is a yellowish, warm kind of color, and a little outdated looking compared to the LED which gives you a nice blue whitish color, which really is pretty intense, but also you can actually feel the heat off this bulb verse this one. So, the great part about it is you're getting more light, more efficiently, that will last longer. To change this out. These bolts come in a two-pack. So, we might as well do our fixture. They also come in a six pack. So, if we really wanna update all of our lighting, we can do that pretty easily. With our covers in place, that's our finished product. If lumens are something that speak to you, it's probably because you've done shopping on LED bulbs before. Now these are 215 per bulb. So it's a decent amount of light and being 5,500 K is going to give you a nice white bluish light. There's also other temperature scales available, which can give you a spectrum of colors. But overall, these are extremely bright in a good way without being too intrusive and overall the efficiency, the lifespan, and overall just modern look, make this a really good option for when updating your light or replacing old burnt out bulbs. And that was a look at the Diamond LED replacement bulb for a 9-0-6 or a 9-21 bulb in 5,500 K. Thanks for watching..

Replaced incandescent bulb over stove. This bulb supplies much more light, with less current draw, and runs cooler. Big improvement.

After a year, light is still working great, would buy again from etrailer.

Great led bulbs, makes the trailer brighter inside.


WE have had good luck with these lights as I used them for the ceiling lights that are on the roof of the trailer , so I don't want to change these


These bulbs were the perfect replacement to the dull 921 bulbs for my camper. I dont have experience with LED bulbs and am extremely happy etrailer gave a great description which helped me choose the right replacement.
