Generally, yes.  But pull a bulb and read the number on it-- should be able to find it at any box store.

The ones I'm familiar with that have been used in rvs we've worked on in the last 40 years seem to be smaller in diameter and shorter that home units with bigger ballasts.  Most of them are made by Thin Lite.

All of the flourescent lighting tubes in my coach ('01 Monaco Exec) are 12v. I'm replacing them with LED tubes. Yeah, they are expensive... but they're also much brighter, have no ballast to burn out or burn up and they are said to last a lot longer.

Tom,

 

Are you sure the bulbs are 12 VDC?  Most 12 VDC florescent lights have ballasts so the bulbs are really not 12 VDC though the fixture is powered by 12 VDC.

 

Again, pull one out and read the numbers on it.  Likelihood is you can find it at one of the box stores.

I think they are sold as 12v tubes at Camping World.

I put new bulbs in the  florescent lights in my motorhome and they're not working.

 

I notice there is no ballast. Is this normal not to have one in the florescent light?

 Tell us what brand and model (or bulb number and quantity) and perhaps we can help you.  But, in general florescents do use ballasts.

If it is Thinlite the ballast is a circuit board hidden in the center.

The ballast is definitely under the metal cover in the center of the fixture. Failure of the ballast is common.

If you replace the tubes with LEDs you can remove the ballast and easily wire in the LED tubes which depend on a pigtail for 12v power rather than pins on the end of the tubes.

Just cut out all the spaghetti next of wires under the metal cover, except for the 12v feed from the local on-off switch. Connect the pig tails from the two LED tubes while observing polarity.

You'll find the LED tubes to be much brighter and draw significantly less current.

I'am new to FMCA. just signed up. I have a country coach allure that had 12 overhead thin-lite 15" long 12 volt fluorescent open tube fixtures. The fixtures are 12 volt but the F15t8cw lamps are the same you would use in household application. I removed these fixtures, purchased through E-bay LED Lights, I went with the warm white color. You need to be careful of color, the higher the kelvin ( color degree temp) the more blue white they are. Give off more lumens that the fluorescent, no heat and less power draw.
