I replaced every ceiling light and reading light in my 5th wheel with these 3 years ago. I love them, I love the color, and I love how much brighter these are than the old incandescent lights that were in my rv before. These are slightly warmer (4500 kelvin) than daylight (5k-6500 kelvin), but WAY cooler than the normal incandescent bulbs (around 2700 kelvin), which is a great compromise for my wife and me. (I prefer true daylight color, she prefers the normal ugly yellow color, but these are close enough to daylight for me.) Anyway, as for durability, I have both singles and doubles installed, about 10 each, and have traveled 10s of thousands of miles on smooth and not-smooth highways. No problems, haven't had to replace any of them and no LEDs are "out". Highest recommendation, though I don't have any other fixtures to compare them to other than the stock incandescent ones. I know newer RVs already have LED fixtures installed in them, but for older units that don't, this is a wonderful upgrade.

My only negative comment is that almost all RVs are wired black = positive and white = negative. These lights come with black and red wires. Not black and white wires. If you get these, they are wired red = positive and black = negative. Black is NOT positive on these lights. They install easily and work well. I bought two of them and am very happy that they have a choice of one or two lamps on depending on our needs. Even with two lights on, they draw less than the single incandescent light that came with the camper.
Our camper is an '06 Palomino Pony so it's not very big. But, these lights give us many options of how much light we want.

Pros:

High quality fixture and LEDs
Bright
Does NOT interfere with TV/Internet

Cons:

Was 6500k (was advertised as around 4000k which is what I wanted)
Casts light subtle light spots (as other reviewers said)
Low Frequency + Blinding = Headaches (if looked at directly for too long)

With all the faults I'm so happy to get something like this that has functional quality and is still much better than the incandescents it replaced I'm still giving it 3 stars.

Great product, I've replaced bulbs in the factory lights with LEDs. 50% of those worked, the ones that did, got just as hot as incandescent bulbs.
They, smoked, stunk and looked like they would catch on fire. These are very easy to install, 2 out of the 12 I bought needed the bulb connection tightened, but if you can't figure that out, then you shouldn't be installing them. These are very bright, zero heat, great product. A word to the wise, don't bother buying the single fixtures, these draw 1/4 of the amps, so you might as well buy doubles. One other point, look at the prices, do the math. One pack, double fixture is cheaper then the multi packs. Double fixture (6 pack) works out to 14.16 each, double fixture (3 pack) works out to $21.00 each, double fixture (1 Pack) is 11.46. Although the double fixture (6 pack) doesn't have a color temperature rating like the single and triple (4000-4500K), they should all be the same, just packaged differently, very quick shipping.

Gold Stars Natural White LED Dome Light - I recently had the factory light above the bathroom sink in my travel trailer have a switch go bad. I could have purchased an exact replacement for a few buck less, but I wanted to go with an LED light. This was just about an inch longer than my old light and I had to make some new screw holes in the ceiling, but you don't see them anyways. I really like the color of the light that this LED fixture gives off, its very bright, but not blinding at the same time. I had no problems with the installation. Simply remove the lens covers (carefully) using the supplied wire nuts attach the 2 wires (need correct polarity for the LED's to work) from this to the 2 wires from your RV, install the 8 mounting screws and replace your lens covers. Another nice feature is the dual switches, so if you don't need as much light you can turn on on side or the other or both. I also purchase a 2nd fixture for my in-laws camper above their bed (also had a switch go bad). I will be buying more of these if and when other lights in my camper decide to quit working.
