Video Transcript for Review of Diamond Vehicle Lights - Replacement Bulbs - DI38VR

Hi there. I'm Michael with etrailer.com. Today we're going to take a quick look at these LED bulbs. These LED tower bulbs will replace or upgrade your 906 and 921 light bulbs to provide a nice cool white light for many of your applications in your RVs, trailers, boats, or vehicle. The wedge base mount is also going to allow these to be compatible with your 161, 168 and 194 type bulbs. Just with the base there, the wedge base, it will work with those, so you do want to make sure that the bulb portion will fit in whatever housing you have for those 161, 168 and 194 bases.

So, it is right about one inch tall, and our diameter, we're looking at right about a half inch in total. So, as long as that will fit in those 161, 168 and 194 fixtures, you should be fine, but it will definitely work with all of your 906 and 921 bulb applications.You can see these do have a multi-directional design, so that it will emit 360 degrees of light around the bulb. These are 12 volt bulbs. You can see there's six of them, and each bulb has 13 of these LEDs, light-emitting diodes, and they're going to give you a nice cool white light. They're a 5,500 Kelvin light.

If you're not familiar with the light scale, that is pretty close to exactly center, so it is very white, but it is slightly on the blue side. So, going off this graphic, it's about as close as any graphic can be, but they are just slightly more on the blue side than the pure white, so they're going to give you that nice cool white color.Now, if you're not familiar with LEDs, they are going to be a much better replacement than your incandescent bulbs. They're rated for about 50,000 hours because they don't have the brittle filament on the inside. They're not going to break down as much or as easily, so you're not going to have to replace them nearly as often. And not only that, they're also more efficient.

So they're going to provide brighter light with less power output. These bulbs will give you a light output of 215 lumens. They only pull 1.8 watts, comparable to an incandescent bulb that is pulling 18 watts. So, quite a bit les.On a 12 volt system, they're only going to draw 0.15 amps. So, not very much.

They're not going to draw very much power whatsoever, and they are going to give you a nice bright light. They are compatible with your dimmable features. So, if you've got a dimmable light that you're wanting replacement bulbs for, these will work well for that. They do have a built-in surge protector that's going to help safeguard the internal electronics, so it's not going to overheat or anything like that, cause a short. They do have a non-polarized design, so you're not going to have to worry about rewiring or anything like that. They will fit in with the wiring that you already have.And I do want to show you just how bright these are going to be. So, going to hook him up to a power source here, give you a little display of their brightness. So, you can see it's going to be our 215 lumens. So, nice and bright. Going to give us that 360 degree light glowing around each bulb. So, very nice little bulbs here. They are going to the last. They're going to come with a five year limited warranty. They will probably last you much longer than that, being the LEDs, but if you have any problems within that five years, you can work with the manufacturer, they'll help you out with that. But overall, I think these are going to be a great option for you if you're wanting to replace your 906 or 921 light bulbs. Just the brightness, color of the light, the LEDs being longer lasting. I think they're going to be a great option for you. So that's going to complete our look at these LED lights. Again, I'm Michael with etrailer.com. Thanks for watching.
