By existing U.S. lighting definition, light colors are measured in degrees Kelvin (color temperature).

Warm white is approx 3,000 K which is close to a normal 100 watt incandescent bulb in color temperature.

Cool white is approx 4,000 K.

The color that I like is 3,500 K.

The terms "warm white, cool white, etc. really mean little".

Unfortunately color temperature in K is a lot like color in general. We all like different colors and we all like different color temperatures.

A lot of the LED's you get on e-bay for low prices are in the 6,000 K range which is getting very white and even into the bluish range. The reason the prices are so low is LED's that produce this color temperature are the cheapest. It costs more to make LED's that produce warm color temperatures.

Also, the cheaper LED's aren't electrically controlled very well. LED's are very particular on the electrical characteristics they see. The higher priced LED's contain electronics that allow them to work better and longer.

This technology is still evolving and is getting better all the time, I'm just not ready for a major expense just yet. I do have an LED replacement for my 921 outdoor fixture. I really don't care about the color, I just got tired of replacing it every couple of weeks.

These are the lights I used. And I see that now the price has dropped another $.45 cents, great bargan.

Will this replace the 921 bulb in my Jayco X23B?

Glsimms, yes these will work, but you can order them on-line for less, just spend a little time and look.

Here are the ones that I recently ordered to finish off my lights. I also ordered a few extra, just in case a few die.

Thanks for the reply and the link.

Is this what you use in your ceiling dome lights? My fixtures have 2 bulbs, did you replace both bulbs?

Thanks, Gerard

I started out only replacing one bulb in each fixture and removing the other bulb. I am now adding a second LED to the blank side. The single fixture bulbs above the sofa and sink were changed out during the first round. I added bunk end lights shortly after buying the TT, those fixtures where changed to the same LED lights.

By the end of next week EVERY bulb inside the trailer will be utilizing LED technology. I even changed the frig light (found a real cheap festoon LED unit). I also plan to change the Stove light to two LEDs as the light is not very good there. I am also going to change the outside patio area lights, only one of them can I use this same led unit. The step light will also be changed, but it takes a very small LED to fit in that fixture. In addition I added two more light fixtures inside the TT over the dinette under the upper cabinet for additional lighting; those lights will be changed out once I receive this next order.

I had intentions to procure a new switch so I could turn on each side of the dual fixtures independently and put different brightness of leds in each side. However, I have not been able to locate a dps switch that is compatible with the housing.

I purchased 10 to get started. In all I will have purchased 22 of these led boards, 20 will be installed and 2 will be spares (just in case). Then a few others leds for the step light and the frig.

The ONLY thing wrong with them is the foam adhesive. The manufacture has chosen the wrong adhesive and it will not hold up to the heat, and it will shrink up to a small ball after a short run time. I replaced the OEM foam adhesive with a heat transfer foam adhesive that I received out of the lab at work. Some people use construction adhesive to glue them onto the light fixture.

I have the same failures with the halogens in our Greyhawk. I will be changing to LEDs soon. Thanks for the info.

Realize this an older thread but I thought I'd share my experience. Originally I purchased the eBay "Chinese" 36 led arrays that came with a variety adapters. They work, the color was a bit cool white for my taste, I feel they still run hot in the fixture and the adhesive just doesn't hold up causing the array falls to the fixture lens.

Today I went back to eBay to what other options may be avaible. I found some disk type 24 led arrays that don't require the adhesive. These are shipping from a seller in new jersey, but based on the price (10 units @ $12.34) they must be coming from China. They claim to 3000k-3300k much warmer white than my current arrays, and 100Lm which is slightly less than the current ones.

I'll be sure to let other know how they turn out for me.

Clubhouse, these are some interesting lights. You may find these leds not to be bright enough at 100 Lums. My 48 LED boards are 190 lums.

My DW loves to read. With only one 48 led board over the dinette (mounted at the ceiling) my DW did not like it as it was bright enough to sit and read her books. However, they (190 lum) are bright enough for other tasks. I received my most recent order of leds right after our last trip (delayed in customs for two weeks) so I do not know if I have fixed the issues by adding a second led to the ceiling fixture.

I do know the incandescent in the new fixtures I added to the overhead cabinet (incandescent bulbs) over the dinette did help significantly in her reading time.

We changed out all our Halogen "Puck" lights to LEDs a little over a year ago.
Light output is the same and the light color is similar to Halogen bulbs they replaced.
Since we Fulltime on our Pinnacle they get used a lot of hours, had a couple of bulbs fail early on, supplier replaced all LEDs in the batch / lot.
All other LEDs have been fine with no faiilures in a little over a year.

3 month update: The lights I installed are working wonderfully. Not a single issue with them. In the past three months, we have travelled approximately 4500 miles and thru varying climates and terrain. Very pleased...
