Lights - Warmer Please

We recently traded our Safari 27FB for a 2010 31D classic. In our shake down trip we found the overhead fluorescent lights to be too "cool". According to the tube they are "8W/T5 12 Volt/Inch at 4100K"

I found a web site for warmer replacements (T5 8W Search Results | Bulbs.com) but am confused what to get. Anyone change their tubes yet?

I also found a site that compares CRI values to Degrees (CRI (Color Rendering Index) Chart) but I'm not sure it helped.

The tubes I'm looking at are vastly different in price.

Thanks

PS: I have been lurking on the this site for years. It has been quite helpful. I signed up for a subscription!

I changed mine a couple months ago for the same reason. The stock bulbs are not only cool but have low output and poor color rendition.

I had a thread on this here:

http://www.airforums.com/forums/f447...bes-68110.html

In short I got mine from alldaylighting.com. They're supposed to be Philips Ultralume 30 tubes but when they arrived they were in European packaging. I believe the tubes are the same and they certainly perform well, though there has been some flickering which I attribute to poor ballast quality. These tubes are supposed to have a CRI of 85.

You will need two F15T8 bulbs for the lavatory in addition to the 12 F8T5 bulbs everywhere else.

The Ultralume 30s blend in well with the dinette and the halogen reading lights. On full brightness, the halogen lights are a little cooler than the fluorescents, but not much.

The cheap ones will be warmer but they will not be as bright and will render colors less accurately.

The expensive ones will make more light with the same watts and will render colors almost as well as an incandescent light.

I use Philips Soft White 8 watt T5 tubes from Home Depot. They are about $5.50 or so, but available locally. The info on the back of the package is:

Light Output 450 Lumens
Energy Used 8 Watts
Life 7500 Hours
Color Rendering 85
Color Temperature 3000K

I have four spares, 3 made in China and 1 made in Japan. They all say Soft White on the tubes as well as the package.

The larger fixtures in my Excella, the one over the galley sink and the identical with which one I replaced a small one in the hall, take a 21 inch 13T5. The info on the back of the package is:

Light Output 1000 Lumens
Energy Used 13 Watts
Life 7500 Hours
Color Rendering 85
Color Temperature 3000K

I have two spares, both made in Poland. The package says Soft White, but these tubes say Ultralume.

I agree with Jammer. These make a great difference in the light quality inside the trailer. Colors are great and it feels natural, not like you are underwater or in a morgue like cool whites. Replacing the cool whites was the first thing I did when I got the Excella.

Just a nod of agreement with the above three posts.

For warm white you want 3000K color temperature.

You want color rendering index (CRI) in the 80s


The original factory equipped lamps are probably 4100K cool white. They very likely are CRI of 60.

Thanks for the answers. I found "warmer" tubes at Home Depot as mentioned above and replaced the "cool" tubes. Much better! I also "figured out" the search feature - use google - and found the previous answers that were there all along. Great site.
